Trying to add object onto text file - python

I am trying to upload a bunch of objects onto a text file in an organized manner but I keep on getting an error. I am not sure about objects and how to arrange them so they appear in the text document.
class Customer:
def __init__(self, name, date, address, hkid, acc):
self.name = name
self.date = date
self.address = address
self.hkid = hkid
self.acc = acc
customer1 = Customer ("Sarah Parker","1/1/2000","Hong Kong, Tai Koo,Tai Koo Shing Block 22,Floor 10, Flat 1", "X1343434","2222")
customer2 = Customer ("Joe Momo","7/11/2002","Hong Kong, Tai Koo, Tai Koo Shing, Block 22, Floor 10, Flat 5", "C2327934","1234")
customer3 = Customer ("Brent Gamez","7/20/2002","Hong Kong, Tung Chung, Yun Tung, Block 33, Floor 10, Flat 9", "C1357434","2234")
customer4 = Customer ("Jose Gamez","7/20/2002","Hong Kong, Tung Chung, Yun Tung, Block 33, Floor 10, Flat 9", "C1357434","2234")
customer5 =Customer ("Viraj Ghuman","7/20/2002","Hong Kong, Heng Fa Chuen, 100 Shing Tai Road, Block 22, Floor 20, Flat 1", "C6969689","100000")
allCustom = [customer1, customer2, customer3, customer4, customer5]
def UpdateFile ():
global allCustom
OutFile = open("CustomInfo.txt","w")
for i in range (len(allCustom)):
for c in range (i):
OutFile.write(allCustom[i["\n","Name:",c.name,"\n"]])
OutFile.write(allCustom[i["Birth Date:",c.date,"\n"]])
OutFile.write(allCustom[i["Address:",c.address,"\n"]])
OutFile.write(allCustom[i["HKID:",c.hkid,"\n"]])
OutFile.write(allCustom[i["Account value:", c.acc,"\n"]])
OutFile.close()


i and c are integer list indexes. You can't use c.name because it's not a Customer object. And you can't index i[...] because it's not a container.
You don't need nested loops, just one loop over all the customers. Your loop iterates i from 0 to 4. On the first iteration it iterates 0 times, on the second iteration it processes c == 0, on the third iteration it processes c == 0 and c == 1, and so on.
Then you can use a formatting operator to put the attributes into the strings that you're writing to the file (I've used f-strings below, but you can also use the % operator or the .format() method).
def updateFile():
global allCustom;
with open("CustomInfo.txt", "w") as OutFile:
for c in allCustom:
OutFile.write(f"\nName:{c.name}\n")
OutFile.write(f"Birth Date:{c.date}\n")
OutFile.write(f"Address:{c.address}\n")
OutFile.write(f"HKID:{c.hkid}\n")
OutFile.write(f"Account value:{c.acc}\n")


You don't need two loops to get each object info. Maybe this is what you are looking for.
def UpdateFile():
global allCustom
Outfile = open("CustomInfo.txt", "w")
for i in allCustom:
Outfile.write(f'\nName: {i.name}\n')
...
Outfile.close()

How do I perform a search on a text file from a users input

The question I am trying to answer is
Query if a book title is available and present option of (a) increasing stock level or (b) decreasing the stock level, due to a sale. If the stock level is decreased to zero indicate to the user that the book is currently out of stock.
This is the text file
#Listing showing sample book details
#AUTHOR, TITLE, FORMAT, PUBLISHER, COST?, STOCK, GENRE
P.G. Wodehouse, Right Ho Jeeves, hb, Penguin, 10.99, 5, fiction
A. Pais, Subtle is the Lord, pb, OUP, 12.99, 2, biography
A. Calaprice, The Quotable Einstein, pb, PUP, 7.99, 6, science
M. Faraday, The Chemical History of a Candle, pb, Cherokee, 5.99, 1, science
C. Smith, Energy and Empire, hb, CUP, 60, 1, science
J. Herschel, Popular Lectures, hb, CUP, 25, 1, science
C.S. Lewis, The Screwtape Letters, pb, Fount, 6.99, 16, religion
J.R.R. Tolkein, The Hobbit, pb, Harper Collins, 7.99, 12, fiction
C.S. Lewis, The Four Loves, pb, Fount, 6.99, 7, religion
E. Heisenberg, Inner Exile, hb, Birkhauser, 24.95, 1, biography
G.G. Stokes, Natural Theology, hb, Black, 30, 1, religion
And this is the code i have so far
def Task5():
again = 'y'
while again == 'y':
desc = input('Enter the title of the book you would like to search for: ')
for bookrecord in book_list:
if desc in book_list:
print('Book found')
else:
print('Book not found')
break
again = input('\nWould you like to search again(press y for yes)').lower()
i already have a function which reads from the text file:
book_list = []
def readbook():
infile = open('book_data_file.txt')
for row in infile:
start = 0 # used to start at the beginning of each line
string_builder = []
if not(row.startswith('#')):
for index in range(len(row)):
if row[index] ==',' or index ==len(row)-1:
string_builder.append(row[start:index])
start = index+1
book_list.append(string_builder)
infile.close()
Any one have an idea on how i complete this task? :)

Get the titles from the book_list variable.
titles = [data[1].strip() for data in book_list]
Remove any white-space from the desc variable.
desc = desc.strip()
For instance If I'm searching for Popular Lectures book, but If I type Popular Lectures then I couldn't find it in the book_list Therefore you should remove the white characters from the input.
If the book is avail, then get the book name and stock value from the book_list
info = [(title, int(book_list[idx][5].strip())) for idx, title in enumerate(titles) if desc in title][0]
bk_nm, stock = info
Print the current situation
if stock == 0:
print("{} is currently not avail".format(bk_nm))
else:
print("{} is avail w/ stock {}".format(bk_nm, stock))
Example:
Enter the title of the book you would like to search for: Popular Lectures
Popular Lectures is avail w/ stock 1
Would you like to search again(press y for yes)y
Enter the title of the book you would like to search for: Chemical
The Chemical History of a Candle is avail w/ stock 1
Would you like to search again(press y for yes)n
Code:
book_list = []
def task5():
titles = [data[1].strip() for data in book_list]
again = 'y'
while again == 'y':
desc = input('Enter the title of the book you would like to search for: ')
desc = desc.strip() # Remove any white space
stock = [int(book_list[idx][5].strip()) for idx, title in enumerate(titles) if desc in title][0]
if stock == 0:
print("{} is currently not avail".format(desc))
else:
print("{} is avail w/ stock {}".format(desc, stock))
again = input('\nWould you like to search again(press y for yes)').lower()
def read_txt():
infile = open('book_data_file.txt')
for row in infile:
start = 0 # used to start at the beginning of each line
string_builder = []
if not (row.startswith('#')):
for index in range(len(row)):
if row[index] == ',' or index == len(row) - 1:
string_builder.append(row[start:index])
start = index + 1
book_list.append(string_builder)
infile.close()
if __name__ == '__main__':
read_txt()

Python Classes and Object assignment

I need to write a program that does the following:
First, find the County that has the highest turnout, i.e. the highest percentage of the
population who voted, using the objects’ population and voters attributes
Then, return a tuple containing the name of the County with the highest turnout and the
percentage of the population who voted, in that order; the percentage should be
represented as a number between 0 and 1.
I took a crack at it, but am getting the following error:
Error on line 19:
allegheny = County("allegheny", 1000490, 645469)
TypeError: object() takes no parameters
Here is what I've done so far. Thank you so much for your help.

Search in List; Display names based on search input

I have sought different articles here about searching data from a list, but nothing seems to be working right or is appropriate in what I am supposed to implement.
I have this pre-created module with over 500 list (they are strings, yes, but is considered as list when called into function; see code below) of names, city, email, etc. The following are just a chunk of it.

"""
a = empRecords.strip().split(";")
And I have the following code for searching:
import empData as x
def seecity():
empCitylist = list()
for ct in x.a:
empCt = ct.strip().split(",")
empCitylist.append(empCt)
t = sorted(empCitylist, key=lambda x: x[3])
for c in t:
city = (c[3])
print(city)
live_city = input("Enter city: ")
for cy in city:
if live_city in cy:
print(c[1])
# print("Name: "+ c[1] + ",", c[0], "| Current City: " + c[3])
Forgive my idiotic approach as I am new to Python. However, what I am trying to do is user will input the city, then the results should display the employee's last name, first name who are living in that city (I dunno if I made sense lol)
By the way, the code I used above doesn't return any answers. It just loops to the input.
Thank you for helping. Lovelots. <3
PS: the format of the empData is: first name, last name, address, city, country, birthday, zip, phone, and email

You can use the csv module to read easily a file with comma separated values
import csv
with open('test.csv', newline='') as csvfile:
records = list(csv.reader(csvfile))
def search(data, elem, index):
out = list()
for row in data:
if row[index] == elem:
out.append(row)
return out
#test
print(search(records, 'Orlando', 3))

Based on your original code, you can do it like this:
# Make list of list records, sorted by city
t = sorted((ct.strip().split(",") for ct in x.a), key=lambda x: x[3])
# List cities
print("Cities in DB:")
for c in t:
city = (c[3])
print("-", city)
# Define search function
def seecity():
live_city = input("Enter city: ")
for c in t:
if live_city == c[3]:
print("Name: "+ c[1] + ",", c[0], "| Current City: " + c[3])
seecity()
Then, after you understand what's going on, do as #Hoxha Alban suggested, and use the csv module.

The beauty of python lies in list comprehension.

Error when creating dictionaries from text files

I've been working on a function which will update two dictionaries (similar authors, and awards they've won) from an open text file. The text file looks something like this:
Brabudy, Ray
Hugo Award
Nebula Award
Saturn Award
Ellison, Harlan
Heinlein, Robert
Asimov, Isaac
Clarke, Arthur
Ellison, Harlan
Nebula Award
Hugo Award
Locus Award
Stephenson, Neil
Vonnegut, Kurt
Morgan, Richard
Adams, Douglas
And so on. The first name is an authors name (last name first, first name last), followed by awards they may have won, and then authors who are similar to them. This is what I've got so far:
def load_author_dicts(text_file, similar_authors, awards_authors):
name_of_author = True
awards = False
similar = False
for line in text_file:
if name_of_author:
author = line.split(', ')
nameA = author[1].strip() + ' ' + author[0].strip()
name_of_author = False
awards = True
continue
if awards:
if ',' in line:
awards = False
similar = True
else:
if nameA in awards_authors:
listawards = awards_authors[nameA]
listawards.append(line.strip())
else:
listawards = []
listawards.append(line.strip()
awards_authors[nameA] = listawards
if similar:
if line == '\n':
similar = False
name_of_author = True
else:
sim_author = line.split(', ')
nameS = sim_author[1].strip() + ' ' + sim_author[0].strip()
if nameA in similar_authors:
similar_list = similar_authors[nameA]
similar_list.append(nameS)
else:
similar_list = []
similar_list.append(nameS)
similar_authors[nameA] = similar_list
continue
This works great! However, if the text file contains an entry with just a name (i.e. no awards, and no similar authors), it screws the whole thing up, generating an IndexError: list index out of range at this part Zname = sim_author[1].strip()+" "+sim_author[0].strip() )
How can I fix this? Maybe with a 'try, except function' in that area?
Also, I wouldn't mind getting rid of those continue functions, I wasn't sure how else to keep it going. I'm still pretty new to this, so any help would be much appreciated! I keep trying stuff and it changes another section I didn't want changed, so I figured I'd ask the experts.

How about doing it this way, just to get the data in, then manipulate the dictionary any ways you want.
test.txt contains your data
Brabudy, Ray
Hugo Award
Nebula Award
Saturn Award
Ellison, Harlan
Heinlein, Robert
Asimov, Isaac
Clarke, Arthur
Ellison, Harlan
Nebula Award
Hugo Award
Locus Award
Stephenson, Neil
Vonnegut, Kurt
Morgan, Richard
Adams, Douglas
And my code to parse it.
award_parse.py
data = {}
name = ""
awards = []
f = open("test.txt")
for l in f:
# make sure the line is not blank don't process blank lines
if not l.strip() == "":
# if this is a name and we're not already working on an author then set the author
# otherwise treat this as a new author and set the existing author to a key in the dictionary
if "," in l and len(name) == 0:
name = l.strip()
elif "," in l and len(name) > 0:
# check to see if recipient is already in list, add to end of existing list if he/she already
# exists.
if not name.strip() in data:
data[name] = awards
else:
data[name].extend(awards)
name = l.strip()
awards = []
# process any lines that are not blank, and do not have a ,
else:
awards.append(l.strip())
f.close()
for k, v in data.items():
print("%s got the following awards: %s" % (k,v))

Split a file into a list

This is what I have so far:
EX1 = open('ex1.txt')
EX1READ = EX1.read()
X1READ.splitlines(0)
['jk43:23 Marfield Lane:Plainview:NY:10023',
'axe99:315 W. 115th Street, Apt. 11B:New York:NY:10027',
'jab44:23 Rivington Street, Apt. 3R:New York:NY:10002',
'ap172:19 Boxer Rd.:New York:NY:10005',
'jb23:115 Karas Dr.:Jersey City:NJ:07127',
'jb29:119 Xylon Dr.:Jersey City:NJ:07127',
'ak9:234 Main Street:Philadelphia:PA:08990']
I'd like to be able to just grab the userId from this list and print it alphabetized. Any hints would be great.

userIds = []
EX1 = open('ex1.txt')
X1READ = EX1.readlines()
for line in X1READ:
useridname = line.split(" ")[0].split(":")[0];
userid = line.split(" ")[0].split(":")[1]
userIds.append([useridname, userid])
I'm sure there are more Pythonic ways to do this, but my method will return an list of lists, where each child list in the parent list is formatted like this:
["jk43", "23"]
So to get the first user id and id number, you'd do this:
firstUserId = userIds[0][0] + ": " + userIds[0][1]
Which would output
"jk43: 23"
To sort the list of IDs, you'd do something like this:
userIds = sorted(userIds, key = id: id[0])

Assuming the part before the first ":" is the userID you could do it in a more pythonic way like that:
with open("ex1.txt") as f:
lines = f.readlines()
userIDs = [l.split(":",1)[0] for l in lines]
print "\n".join(sorted(userIDs))

This does it:
IDs=[]
with open('ex1.txt', 'rb') as f:
for line in f:
IDs.append(line.split(':')[0])
print sorted(IDs)
Prints:
['ak9', 'ap172', 'axe99', 'jab44', 'jb23', 'jb29', 'jk43']
If your user id's like jk43:23 use IDs.append(line.split(' ')[0]) and that prints:
['ak9:234', 'ap172:19', 'axe99:315', 'jab44:23', 'jb23:115', 'jb29:119', 'jk43:23']
If your user ids are the number only, use IDs.append(int(line.split(' ')[0].split(':')[1])) which prints:
[19, 23, 23, 115, 119, 234, 315]
