Python Not Reading From A Text File Correctly?

I have a code where I have an email and a password in a text file in a list, formatted like this: ['tom@gmail.com','Password1'],['harry@gmail.com','Password2]. My code reads from t

Solution 1:

You are reading text with line separators. Your lines don't look like this:

tom@gmail.com,Password1

They actually look like this:

tom@gmail.com,Password1\n

When splitting that on the comma, you get this:

line = ['tom@gmail.com', 'Password1\n']

and the test 'Password1' in line fails, but 'Password1\n' in line would succeed.

The \n is a newline character. You'd need to remove that first; you could use str.strip() to handily remove all whitespace from the start and end:

for line in file:
    line = line.strip().split(",")
    if email in line:
        print("Correct email")
    if password in line:
        print("Correct Password")

Rather than manually split, you can use the csv module to read your file:

import csv

withopen("logindata.txt", "r") as file:
    reader = csv.reader(file)
    for user, pw in reader:
        if email == user:
            print("Correct email")
        if password == pw:
            print("Correct Password")
