How to get a specific field from a text file using python

I have a text file named login.txt has the following data:

{'Username':'hazem', 'Password':'000'}
{'Username':'john', 'Password':'123'}

And I have a function has two parameters Username and Password

Once I pass the parameters as example john and 123

I want to check if the username and password is right or not from the text file.

But I don’t know exactly how to read the key value pairs data from a text file.

Thanks in advance.

>Solution :

Use a combination of iterating over the files + ast.literal_eval.

For example:

import ast

file_location = 'SomeFileLocation\text_file.txt'
# Open File and iterate over lines
with open(file_location, 'r+') as f:
    for single_line in f:
        dict_to_check = ast.literal_eval(single_line)
        user_name = dict_to_check['Username']
        password = dict_to_check['Password']
