How to speed up this python script with multiprocessing - python

I have a script that get data from a dataframe, use those data to make a request to a website, using fuzzywuzzy module find the exact href and then runs a function to scrape odds. I would speed up this script with the multiprocessing module, it is possible?
Date HomeTeam AwayTeam
0 Monday 6 December 2021 20:00 Everton Arsenal
1 Monday 6 December 2021 17:30 Empoli Udinese
2 Monday 6 December 2021 19:45 Cagliari Torino
3 Monday 6 December 2021 20:00 Getafe Athletic Bilbao
4 Monday 6 December 2021 15:00 Real Zaragoza Eibar
5 Monday 6 December 2021 17:15 Cartagena Tenerife
6 Monday 6 December 2021 20:00 Girona Leganes
7 Monday 6 December 2021 19:45 Niort Toulouse
8 Monday 6 December 2021 19:00 Jong Ajax FC Emmen
9 Monday 6 December 2021 19:00 Jong AZ Excelsior
Script
df = pd.read_excel(path)
dates = df.Date
hometeams = df.HomeTeam
awayteams = df.AwayTeam
matches_odds = list()
for i,(a,b,c) in enumerate(zip(dates, hometeams, awayteams)):
try:
r = requests.get(f'https://www.betexplorer.com/results/soccer/?year={a.split(" ")[3]}&month={monthToNum(a.split(" ")[2])}&day={a.split(" ")[1]}')
except requests.exceptions.ConnectionError:
sleep(10)
r = requests.get(f'https://www.betexplorer.com/results/soccer/?year={a.split(" ")[3]}&month={monthToNum(a.split(" ")[2])}&day={a.split(" ")[1]}')
soup = BeautifulSoup(r.text, 'html.parser')
f = soup.find_all('td', class_="table-main__tt")
for tag in f:
match = fuzz.ratio(f'{b} - {c}', tag.find('a').text)
hour = a.split(" ")[4]
if hour.split(':')[0] == '23':
act_hour = '00' + ':' + hour.split(':')[1]
else:
act_hour = str(int(hour.split(':')[0]) + 1) + ':' + hour.split(':')[1]
if match > 70 and act_hour == tag.find('span').text:
href_id = tag.find('a')['href']
table = get_odds(href_id)
matches_odds.append(table)
print(i, ' of ', len(dates))
PS: The monthToNum function just replace the month name to his number

First, you make a function of your loop body with inputs i, a, b and c. Then, you create a multiprocessing.Pool and submit this function with the proper arguments (i, a, b, c) to the pool.
import multiprocessing
df = pd.read_excel(path)
dates = df.Date
hometeams = df.HomeTeam
awayteams = df.AwayTeam
matches_odds = list()
def fetch(data):
i, (a, b, c) = data
try:
r = requests.get(f'https://www.betexplorer.com/results/soccer/?year={a.split(" ")[3]}&month={monthToNum(a.split(" ")[2])}&day={a.split(" ")[1]}')
except requests.exceptions.ConnectionError:
sleep(10)
r = requests.get(f'https://www.betexplorer.com/results/soccer/?year={a.split(" ")[3]}&month={monthToNum(a.split(" ")[2])}&day={a.split(" ")[1]}')
soup = BeautifulSoup(r.text, 'html.parser')
f = soup.find_all('td', class_="table-main__tt")
for tag in f:
match = fuzz.ratio(f'{b} - {c}', tag.find('a').text)
hour = a.split(" ")[4]
if hour.split(':')[0] == '23':
act_hour = '00' + ':' + hour.split(':')[1]
else:
act_hour = str(int(hour.split(':')[0]) + 1) + ':' + hour.split(':')[1]
if match > 70 and act_hour == tag.find('span').text:
href_id = tag.find('a')['href']
table = get_odds(href_id)
matches_odds.append(table)
print(i, ' of ', len(dates))
if __name__ == '__main__':
num_processes = 20
with multiprocessing.Pool(num_processes) as pool:
pool.map(fetch, enumerate(zip(dates, hometeams, awayteams)))
Besides, multiprocessing is not the only way to improve the speed. Asynchronous programming can be used as well and is probably better for this scenario, although multiprocessing does the job, too - just want to mention that.
If carefully read the Python multiprocessing documentation, then it'll be obvious.

cannot scrape ratings

My issue is that I cannot use bs4 to scrape sub ratings in its reviews.
Below is an example:
So far, I have discovered where these stars are, but their codes are the same regardless of the color (i.e., green or grey)... I need to be able to identify the color to identify the ratings, not just scrape the stars. Below is my code:
url='https://www.glassdoor.com/Reviews/Walmart-Reviews-E715_P2.htm?filter.iso3Language=eng'
response = requests.get(url)
soup = BeautifulSoup(response.text, 'html.parser')
com = soup.find(class_ = "ratingNumber mr-xsm")
com1 = soup.find(class_ = "gdReview")
com1_1 = com1.find(class_ = "content")
For getting the star rating breakdown (which seems to have no numeric display or meta value), I don't think there's any very simple-and-straight-forward short method since it's done by css in a style tag connected by a class of the container element.
You could use something like soup.select('style:-soup-contains(".css-1nuumx7")') [ the css-1nuumx7 part is specific to rating mentioned above], but :-soup-contains needs html5lib parser and can be a bit slow, so it's better to figure out the data-emotion-css attribute of the style tag instead:
def getDECstars(starCont, mSoup, outOf=5, isv=False):
classList = starCont.get('class', [])
if type(classList) != list: classList = [classList]
classList = [str(c) for c in classList if str(c).startswith('css-')]
if not classList:
if isv: print('Stars container has no "css-" class')
return None
demc = classList[0].replace('css-', '', 1)
demc_sel = f'style[data-emotion-css="{demc}"]'
cssStyle = mSoup.select_one(demc_sel)
if not cssStyle:
if isv: print(f'Nothing found with selector {demc_sel}')
return None
cssStyle = cssStyle.get_text()
errMsg = ''
if '90deg,#0caa41 ' not in cssStyle: errMsg += 'No #0caa41'
if '%' not in cssStyle.split('90deg,#0caa41 ', 1)[-1][:20]:
errMsg += ' No %'
if not errMsg:
rPerc = cssStyle.split('90deg,#0caa41 ', 1)[-1]
rPerc = rPerc.split('%')[0]
try:
rPerc = float(rPerc)
if 0 <= rPerc <= 100:
if type(outOf) == int and outOf > 0: rPerc = (rPerc/100)*outOf
return float(f'{float(rPerc):.3}')
errMsg = f'{demc_sel} --> "{rPerc}" is out of range'
except: errMsg = f'{demc_sel} --> cannot convert to float "{rPerc}"'
if isv: print(f'{demc_sel} --> unexpected format {errMsg}')
return None
OR, if you don't care so much about why there's a missing rating:
def getDECstars(starCont, mSoup, outOf=5, isv=False):
try:
demc = [c for c in starCont.get('class', []) if c[:4]=='css-'][0].replace('css-', '', 1)
demc_sel = f'style[data-emotion-css="{demc}"]'
rPerc = float(mSoup.select_one(demc_sel).get_text().split('90deg,#0caa41 ', 1)[1].split('%')[0])
return float(f'{(rPerc/100)*outOf if type(outOf) == int and outOf > 0 else rPerc:.3}')
except: return None
Here's an example of how you might use it:
pcCon = 'div.px-std:has(h2 > a.reviewLink) + div.px-std'
pcDiv = f'{pcCon} div.v2__EIReviewDetailsV2__fullWidth'
refDict = {
'rating_num': 'span.ratingNumber',
'emp_status': 'div:has(> div > span.ratingNumber) + span',
'header': 'h2 > a.reviewLink',
'subheader': 'h2:has(> a.reviewLink) + span',
'pros': f'{pcDiv}:first-of-type > p.pb',
'cons': f'{pcDiv}:nth-of-type(2) > p.pb'
}
subRatSel = 'div:has(> .ratingNumber) ~ aside ul > li:has(div ~ div)'
empRevs = []
for r in soup.select('li[id^="empReview_"]'):
rDet = {'reviewId': r.get('id')}
for sr in r.select(subRatSel):
k = sr.select_one('div:first-of-type').get_text(' ').strip()
sval = getDECstars(sr.select_one('div:nth-of-type(2)'), soup)
rDet[f'[rating] {k}'] = sval
for k, sel in refDict.items():
sval = r.select_one(sel)
if sval: sval = sval.get_text(' ').strip()
rDet[k] = sval
empRevs.append(rDet)
If empRevs is viewed as a table:
reviewId
[rating] Work/Life Balance
[rating] Culture & Values
[rating] Diversity & Inclusion
[rating] Career Opportunities
[rating] Compensation and Benefits
[rating] Senior Management
rating_num

Is there a way to break from a range() function at a specific value?

I am new to programming in python and am trying to design a calendar that starts the month depending on the selected start day.
However, I don't know how to stop the print once the number of days has been exceeded(e.g breaks at days=31 when month=="January")
The printed values must be right-aligned additionally.
Here is how I first approached it:
month=input("Enter the month: ")
if month=="January" or month=="March" or month=="May" or month=="July" or month=="August" or month=="October" or month=="December":
days=31
else:
days=30
if month=="February":
days=28
Start_day=input("Enter the start day: ")
print(month)
print("Mo","Tu","We","Th","Fr","Sa","Su")
if Start_day == "Monday":
i=1
if Start_day == "Tuesday":
i=0
if Start_day == "Wednesday":
i=-1
if Start_day == "Thursday":
i=-2
if Start_day == "Friday" :
i=-3
if Start_day == "Saturday":
i=-4
if Start_day == "Sunday":
i=-5
j=1
for j in range(i,days,7):
print(str(j).rjust(2," "),str(j+1).rjust(2," "),str(j+2).rjust(2," "),str(j+3).rjust(2," "),str(j+4).rjust(2," "),str(j+5).rjust(2," "),str(j+6).rjust(2," "))
You could encode it instead as
j=1
for j in range(i,days,7):
for i in range(0,7):
if j+i>days: break
print(str(j+i).rjust(2," "),end=' ')
print('')
This would be called "breaking out of a loop" rather than "breaking from a range function." There is no way to "break from a range function."
Can I suggest overhauling this a bit to be more efficient? You can use dicts and define a custom function to handle the date formatting to prevent some repetition.
To answer your question, you can evaluate the date number during the final loop:
for j in range(i,days,7):
# add to j value via range() and adjust()
# (defined above) to prevent repetition
for k in range(7):
if j + k > 0 and j + k <= days:
print(adjust(j + k), end = ' ') # don't print new line
else:
# print spaces if the number is <1 or >days
print(' ', end = '')
# print new line for a new week
print('\n', end = '')
Full example:
# function to format dates later
def adjust(val):
return str(val).rjust(2," ")
# get inputs
month=input("Enter the month: ")
start_day=input("Enter the start day: ")
# map months to days in a dict
month_to_days={"january":31,
"march":31,
"may":31,
"july":31,
"august":31,
"october":31,
"december":31,
"february":28,
"april":30,
"june":30,
"september":30,
"october":30
}
# map weekdays to int
days_to_int={"monday":1,
"tuesday":0,
"wednesday":-1,
"thursday":-2,
"friday":-3,
"saturday":-4,
"sunday":-5
}
# get the day amount based on the entry, ignoring case
days=month_to_days[month.lower()]
# get the int based on the entry, ignoring case
i=days_to_int[start_day.lower()]
# print month and day headers
print(month)
print("Mo","Tu","We","Th","Fr","Sa","Su")
for j in range(i,days,7):
# add to j value via range() and adjust()
# (defined above) to prevent repetition
for k in range(7):
if j + k > 0 and j + k <= days:
print(adjust(j + k), end = ' ') # don't print new line
else:
# print spaces if the number is <1 or >days
print(' ', end = '')
# print new line for a new week
print('\n', end = '')
Output:
Enter the month: january
Enter the start day: monday
january
Mo Tu We Th Fr Sa Su
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30 31
>>>
Enter the month: june
Enter the start day: wednesday
june
Mo Tu We Th Fr Sa Su
1 2 3 4 5
6 7 8 9 10 11 12
13 14 15 16 17 18 19
20 21 22 23 24 25 26
27 28 29 30
Before you print after your for loop just have an if statement to check for your condition and before you print add a break statement.
Something like:
if statement:
break

How to web scrape from two websites in one script?

I am currently working on a model and need to gather information not just regarding game results
(this link https://www.hltv.org/stats/teams/matches/4991/fnatic?startDate=2019-01-01&endDate=2019-12-31)
but I would also like the script to open another link within the HTML source.. the link is available in the source and it'll take me to a page that explains each matches detailed result,
(as in who want what round, https://www.hltv.org/stats/matches/mapstatsid/89458/cr4zy-vs-fnatic?startDate=2019-01-01&endDate=2019-12-31&contextIds=4991&contextTypes=team), the main objective is I want to know who won the match (from first link) and who won the first round of each individual match (in the second link). Is this possible? This is my current script;
import requests
r = requests.get('https://www.hltv.org/stats/teams/maps/6665/Astralis')
from bs4 import BeautifulSoup
soup = BeautifulSoup(r.text, 'html.parser')
results = soup.find_all('tr')
AstralisResults = []
for result in results[1:]:
date = result.contents[1].text
event = result.contents[3].text
opponent = result.contents[7].text
Map = result.contents[9].text
Score = "'" + result.contents[11].text
WinorLoss = result.contents[13].text
AstralisResults.append((date,event,opponent,Map,Score,WinorLoss))
import pandas as pd
df5 = pd.DataFrame(AstralisResults,columns=['date','event','opponent','Map','Score','WinorLoss'])
df5.to_csv('AstralisResults.csv',index=False,encoding='utf-8')
So I would be looking for the following information:
Date | Opponent | Map | Score | Result | Round1Result |
Looks like the site blocks if you scrape too fast, so had to put in a time delay. There's ways to make this code more efficient, but overall, I think it gets what you asked for:

else:

temp_df = temp_df.merge(round_row_df, left_index=True, right_index=True)
df5 = df5.append(temp_df, sort=True).reset_index(drop=True)

'Round01Result':'Round1Result'})
df5.to_csv('AstralisResults.csv',index=False,encoding='utf-8')

My year list doesn't work on BeautifulSoup. Why?

I'm newbie learning BeautifulSoup. May someone have a look at the following code? I'd like to scrape data from a website without any success. I'd like to create a dataframe with the sum of player arrivals per year and with a column of players average age.
dataframe repeating codes:
img dataframe error
my code:
import pandas as pd
import requests
from bs4 import BeautifulSoup
anos_list = list(range(2005, 2018))
anos_lista = []
valor_contratos_lista = []
idade_média_lista = []
for ano_lista in anos_list:
url = 'https://www.transfermarkt.com/flamengo-rio-de-janeiro/transfers/verein/614/saison_id/'+ str(anos_list) + ''
page = requests.get(url, headers={'User-Agent': 'Custom5'})
soup = BeautifulSoup(page.text, 'html.parser')
tag_list = soup.tfoot.find_all('td')
valor = (tag_list[0].string)
idade = (tag_list[1].string)
ano = ano_lista
valor_contratos_lista.append(valor)
idade_media_lista.append(idade)
anos_lista.append(ano)
flamengo_df = pd.DataFrame({'Ano': ano_lista,
'Despesa com contratações':valor_contratos_lista,
'Média de idade': idade_média_lista
})
flamengo_df.to_csv('flamengo.csv', encoding = 'utf-8')`
Here's my approach:
Using Beautiful Soup + Regex:
import requests
from bs4 import BeautifulSoup
import re
import numpy as np
# Set min and max years as variables
min_year = 2005
max_year = 2019
year_range = list(range(min_year, 2019+1))
base_url = 'https://www.transfermarkt.com/flamengo-rio-de-janeiro/transfers/verein/614/saison_id/'
# Begin iterating
records = []
for year in year_range:
url = base_url+str(year)
# get the page
page = requests.get(url, headers={'User-Agent': 'Custom5'})
soup = BeautifulSoup(page.text, 'html.parser')
# I used the class of "responsive table"
tables = soup.find_all('div',{'class':'responsive-table'})
rows = tables[0].find_all('tr')
cells = [row.find_all('td', {'class':'zentriert'}) for row in rows]
# get variable names:
variables = [x.text for x in rows[0].find_all('th')]
variables_values = {x:[] for x in variables}
# get values
for row in rows:
values = [' '.join(x.text.split()) for x in row.find_all('td')]
values = [x for x in values if x!='']
if len(variables)< len(values):
values.pop(4)
values.pop(2)
for k,v in zip(variables_values.keys(), values):
variables_values[k].append(v)
num_pattern = re.compile('[0-9,]+')
to_float = lambda x: float(x) if x!='' else np.NAN
get_nums = lambda x: to_float(''.join(num_pattern.findall(x)).replace(',','.'))
# Add values to an individual record
rec = {
'Url':url,
'Year':year,
'Total Transfers':len(variables_values['Player']),
'Avg Age': np.mean([int(x) for x in variables_values['Age']]),
'Avg Cost': np.nanmean([get_nums(x) for x in variables_values['Fee'] if ('loan' not in x)]),
'Total Cost': np.nansum([get_nums(x) for x in variables_values['Fee'] if ('loan' not in x)]),
}
# Store record
records.append(rec)
Thereafter, initialize dataframe:
Of note, some of the numbers represent millions and would need to be adjusted for.
import pandas as pd

Print month using the month and day

I need to print month using the month and day. But I cannot seem to move the numbers after '1' to the next line using Python.
# This program shows example of "November" as month and "Sunday" as day.
month = input("Enter the month('January', ...,'December'): ")
day = input("Enter the start day ('Monday', ..., 'Sunday'): ")
n = 1
if month == "January" or month == "March" or month == "May" or month == "July" or month == "August" or month == "October" or month == "December":
x = 31
elif month == "February":
x = 28
else:
x = 30
print(month)
print("Mo Tu We Th Fr Sa Su")
if (day == "Sunday"):
print(" ", end='')
for i in range (1, 7):
for j in range (1, 8):
while n != x+1:
print('%2s' % n, end=' ')
n = n + 1
break
print()
Output looks like this:
November
Mo Tu We Th Fr Sa Su
1 2 3 4 5 6 7
8 9 10 11 12 13 14
15 16 17 18 19 20 21
22 23 24 25 26 27 28
29 30
Some changes.
Instead of having a nested loop, just have a single loop that prints all the dates. Then, inside that loop, make the decision about whether to end the line (if the date you just printed corresponded to a Sunday).
Also, the # of days in month look-up is a bit cleaner, and you now handle more "days" than just Sunday:
day = "Monday"
month = "March"
# Get the number of days in the months
if month in ["January", "March", "May", "July", "August", "October", "December"]:
x = 31
elif month in ["February"]:
x = 28
else:
x = 30
# Get the number of "blank spaces" we need to skip for the first week, and when to break
DAY_OFF = ['Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday', 'Sunday']
off = DAY_OFF.index(day)
print(month)
print("Mo Tu We Th Fr Sa Su")
# Print empty "cells" when the first day starts after Monday
for i in range(off):
print(" ", end=' ')
# Print days of the month
for i in range(x):
print("%2d" % (i+1), end=' ')
# If we just printed the last day of the week, print a newline
if (i + off) % 7 == 6: print()

First problem I see in your code, is: why are you using an while and a break just after start it?
It seems that you only need an if statement, not a while.
Second, you're using the same logic for any line of your calendar, that means: They start on Monday and end on Sunday.
You should change the start point of your inner for loop for your first line, depending on the day that it starts.
A simple dictionary can hold the number associated with each day of the week and for the first week you use it as the start point of the for instead of 1.
And your code will work only for Monday and Sunday as the first day of the month.
To make it works for any first day you should change the way you print spaces, changing it depending on the first day.
The code with the changes:
month = 'November'
day = 'Sunday'
x = 30
n = 1
days = { 'Mo': 1, 'Tu': 2, 'We': 3, 'Th': 4, 'Fr': 5, 'Sa': 6, 'Su': 7 }
print(" "*(days[day[:2]]-1), end='') # print 3 spaces for each day that isn't the first day of the month
start = days[day[:2]] # Set the start of the inner loop to the first day of the month
for i in range (1, 7):
for j in range (start, 8):
start = 1
if n < x+1:
print('%2s' % n, end=' ')
n = n + 1
print()
