How can I list a string in .txt to .csv format using Python?

Question

Here inside of my.txt file are bunch of strings:

I'm trying to trim those sha1 and description then put it in a .csv file like this here in output:

How can I get those string using if(after "\\" and before "->") then place it in csv, it's very hard and I can't think of an easier way.

Answer 1

import csv

INPUTFILE = 'input.txt'
OUTPUTFILE = 'output.csv'
PREFIX = '\\'
DELIMITER = '->'

def read_text_file(inputfile):
    data = []
    with open(inputfile, 'r') as f:
        lines = f.readlines()

    for line in lines:
        line = line.rstrip('\n')
        if not line == '':
            line = line.split(PREFIX, 1)[-1]
            parts = line.split(DELIMITER)
            data.append(parts)

    return data

def write_csv_file(data, outputfile):
    with open(outputfile, 'wb') as csvfile:
        csvwriter = csv.writer(csvfile, delimiter=',', quotechar='"',
                                quoting=csv.QUOTE_ALL)
        for row in data:
            csvwriter.writerow(row)

def main():
    data = read_text_file(INPUTFILE)
    write_csv_file(data, OUTPUTFILE)

if __name__ == '__main__':
    main()
