I'm new to writing code. Using slenium and beautifulsoup, I managed to reach the script I want among dozens of scripts on the web page. I am looking for script [17]. When these codes are executed, the script [17] gives a result as follows.
the last part of my codes
html=driver.page_source
soup=BeautifulSoup(html, "html.parser")
scripts=soup.find_all("script")
x=scripts[17]
print(x)
result, output
note: The list of dates is ahead of the script [17]. slide the bar. Dummy Data

My purpose is to extract this output into a table and save it as a csv file. How can i extract this script as i want?
all dates should be on top, all names should be on the far right, all values should be between the two.
Hisse 2012.12 2013.3 2013.4 ...
ANA 1,114,919,783.60 1,142,792,778.19 1,091,028,645.38 ...
DEN 55,200,000.00 55,920,000.00 45,960,000.00 ....

Solution
The custom-function process_scripts() will produce what you are looking for. I am using the dummy data given below (at the end). First we check that the code does what it is expected and so we create a pandas dataframe to see the output.
You could also open this Colab Jupyter Notebook and run it on Cloud for free. This will allow you to not worry about any installation or setup and simply focus on examining the solution itself.
1. Processing A Single Script
## Define CSV file-output folder-path
OUTPUT_PATH = './output'
## Process scripts
dfs = process_scripts(scripts = [s],
output_path = OUTPUT_PATH,
save_to_csv = False,
verbose = 0)
print(dfs[0].reset_index(drop=True))
Output:
Name 2012.12 ... 2019.12 2020.03
0 ANA 1,114,919,783.60 ... 3,270,000,000.87 2,347,500,000.63
1 DEN 55,200,000.00 ... 125,100,000.00 85,350,000.00
2 SIS 4,425,000,000.00 ... 11,857,500,000.00 9,315,000,000.00
3 TRK 1,692,579,200.00 ... 4,375,000,000.00 3,587,500,000.00
[4 rows x 31 columns]
2. Processing All the Scripts
You can process all your scripts using the custom-define function process_scripts(). The code is given below.
## Define CSV file-output folder-path
OUTPUT_PATH = './output'
## Process scripts
dfs = process_scripts(scripts,
output_path = OUTPUT_PATH,
save_to_csv = True,
verbose = 0)
## To clear the output dir-contents
#!rm -f $OUTPUT_PATH/*
I did this on Google Colab and it worked as expected.
3. Making Paths in OS-agnostic Manner
Making paths for windows or unix based systems could be very different. The following shows you a method to achieve that without having to worry about which OS you will run the code. I have used the os library here. However, I would suggest you to look at the Pathlib library as well.
# Define relative path for output-folder
OUTPUT_PATH = './output'
# Dynamically define absolute path
pwd = os.getcwd() # present-working-directory
OUTPUT_PATH = os.path.join(pwd, os.path.abspath(OUTPUT_PATH))
4. Code: custom function process_scripts()
Here we use the regex (regular expression) library, along with pandas for organizing the data in a tabular format and then writing to csv file. The tqdm library is used to give you a nice progressbar while processing multiple scripts. Please see the comments in the code to know what to do if you are running it not from a jupyter notebook. The os library is used for path manipulation and creation of output-directory.
#pip install -U pandas
#pip install tqdm
import pandas as pd
import re # regex
import os
from tqdm.notebook import tqdm
# Use the following line if not using a jupyter notebook
# from tqdm import tqdm
def process_scripts(scripts,
output_path='./output',
save_to_csv: bool=False,
verbose: int=0):
"""Process all scripts and return a list of dataframes and
optionally write each dataframe to a CSV file.

## Define regex patterns and compile for speed
pat_header = re.compile(r"theCols\[\d+\] = new Array\s*\([\'](\d{4}\.\d{1,2})[\'],\d+,\d+\)")
pat_line = re.compile(r"theRows\[\d+\] = new Array\s*\((.*)\).*")
pat_code = re.compile("([A-Z]{3})")

zfill_digits = len(str(len(scripts)))

## Make a dummy list of scripts
scripts = [s for _ in range(10)]
According to the provided <script> in your question, you can do something like code below to have a list of Dates for each name ANA, DEN ..:
for _ in range(1, len(aaa.split("<b>'"))-1):
s = aaa.split("<b>'")[_].split("'")
print(_)
lst = []
for i in s:
if "</B>" in i:
name = i.split('>')[1].split("<")[0]
print("{} = ".format(name), end="")
if any(j.isdigit() for j in i) and ',' in i:
lst.append(i)
print(lst)
It's just an example code, so it's not that beautiful :)
Hope this will help you.
