[Tutor] why does this fail

[Roelof Wobben]

Hello, 

 

I have this programm :

 

def remove_letter(letter, strng):
    """
      >>> remove_letter('a', 'apple')
      'pple'
      >>> remove_letter('a', 'banana')
      'bnn'
      >>> remove_letter('z', 'banana')
      'banana'
      >>> remove_letter('i', 'Mississippi')
      'Msssspp'
    """
    antwoord=""
    for letter in strng:
        print letter, strng
        if letter in strng:
            print "false"
        else:
            print "true"
    return antwoord

 

x=remove_letter('a', 'apple')
print x 

 

But now everything is false even a in apple.

 

What is here wrong ?
