Python Remove last 3 characters of a string

Question

I\'m trying to remove the last 3 characters from a string in python, I don\'t know what these characters are so I can\'t use rstrip, I also need to remove any white

Answer 1

Removing any and all whitespace:

foo = ''.join(foo.split())

Removing last three characters:

foo = foo[:-3]

Converting to capital letters:

foo = foo.upper()

All of that code in one line:

foo = ''.join(foo.split())[:-3].upper()
