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












3















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.

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

Debugging by printing

for item in bookings:

    line_1 = line[b]

    line_2 = line[c]



    print("Your Answer:", repr(answer))

    print("Actual Answer:", repr(line_2))



    # ...


gives



Your Answer: 'red'

Actual Answer: 'redn'


Aha! A sneaky newline character! Seems like when the program was reading text from the file and splitting the lines, it saved the newline character for you. How sweetly annoying. : |



To remove it, you can use the str.replace() method



# ...



for _ in range(len(bookings)):   # I took the freedom to modify the loop conditions



    line_1 = line[b].replace('n','')

    line_2 = line[c].replace('n','')



    # ...


or change the way lines are read from the file, manually splitting the lines using the str.split() method



# ...



with open('test_1.txt' , 'r') as file_test:

    line = file_test.read().split('n')



for _ in range(len(bookings)):

    line_1 = line[b]

    line_2 = line[c]
