I have two variables that I know are equal but my if statement does not recognise this?

This is my code:

bookings = ['blue,red', 'green,orange', 'yellow, purple']

number = 0

b = 0

c = 1



file_test = open('test_1.txt' , 'wt')



results_song = 



for item in bookings:

   words = bookings[number].split(',')

   results_song.append(words[0])

   results_song.append(words[1])



   number = number + 1



results_song_str = 'n'.join(results_song)

print(results_song_str)



file_test.write(results_song_str)



file_test.close()



file_test = open('test_1.txt' , 'r')



line = file_test.readlines()





for item in bookings:



    line_1 = line[b]

    line_2 = line[c]

    answer = input('If first word is then what is the second word')



    if answer == line_2:

       print('correct')

    else:

       print('wrong')



    b = b + 2

    c = c + 2

However the code will not recognise that answer is equal to line_2. I cannot figure out why this is happening. I have checked that c is the correct number and that line_2 is the same as answer. But I did notice that when I ran the code while printing answer and line_2 that this would return:

red



red

but I never put a new line feature in here.

Any help would be much appreciated as I need to use this code for a school assignment.

before your if statement, print(repr(answer), repr(line_2)), I suspect there is some whitespace not taken into account

[Minor Issue] In your first for loop, you're not using item, it becomes redundant. Use it instead of bookings[number].
