Question

How do I write a one-line (excluding function definition) python function make_filter(limit), which takes in an integer limit, and returns a function that takes in a list of strings, and returns a copy of the list with all strings shorter than limit characters removed. make_filter must be exactly one line of Python code, not including the function signature line ( def make_filter(limit): )

example:

>>> filter5 = make_filter(5)

>>> filter5(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa', 'aaaaaa'])

['aaaaa', 'aaaaaa']

>>> filter2 = make_filter(2)

>>> filter2(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa', 'aaaaaa'])

['aa', 'aaa', 'aaaa', 'aaaaa', 'aaaaaa']

Python 3 thank you.

Program Code:

def make_filter(limit):
    def fun(l):
        return [i for i in l if len(i) >= limit]
    return fun


filter5 = make_filter(5)
result=filter5(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa', 'aaaaaa'])
print(result)


filter2=make_filter(2)
result=filter2(['', 'a', 'aa', 'aaa', 'aaaa', 'aaaaa', 'aaaaaa'])
print(result)
