[Solved] How do I join a list and then delete the last character?

by


If I understand what you’re trying to do correctly, you can just do this:

def littery(lst):
    return ''.join(lst)[:-1]

>>> littery(['Andy', 'Warhol'])
'AndyWarho'

Or if you want to take the last element off of each element of lst, you could do this:

def littery(lst):
    return ''.join(word[:-1] for word in lst)
>>> littery(['Andy', 'Warhol'])
'AndWarho'

Or if you don’t want to build a list in the call, you can do this:

def littery(*lst):
    return ''.join(lst)[:-1]

>>> littery('Andy', 'Warhol')
'AndyWarho'

Or if you want to do it another way, you can do this:

def littery(*lst):
    return ''.join(lst[:-1] + [lst[-1][:-1]])

Or if you might need the slice again at some point:

last = slice(-1)
def littery(*lst):
    return ''.join(lst)[last]
