Solving split string in python without the use of split() function

Question

Faced an interview question in Python that was as follow?

ex: 
input = (\'192.168.15.1\', \'.\', -1) ===> output = (192, 168, 15, 1)
input = (\'192.168.15         


        

Answer 1

Simple and recursive.

def split_str(s,c,i):
    if i == 0:
        return [s]
    else:
        head, _, rest = s.partition(c)
        if rest:
            return [head] + split_str(rest, c, i - 1)
        return [head]
