python :Function to return length of each element in list gives error

Please let me know the reason for the error in the code below.

def lenli(ab):

    results=[]
    for a in ab:
        results.append(len(a))
    return results

shows an error 

TypeError                                 Traceback (most recent call last)
<ipython-input-69-8e23c7ef98a0> in <module>()
----> 1 lenli[ab]

TypeError: 'function' object has no attribute '__getitem__'

thanks sindia

The problem is not in the code you've shown, but in the code that calls it. Functions are called with parentheses, (), not square brackets.

You are calling your function wrong. Square brackets [] are the shorthand for __getitem__ (which lenli does not have). Parentheses () are the shorthand for __call__, which you want.

In short: type lenli(ab).
