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

def split(text, sep, maxsplit=-1):
    parts = []
    end = -1
    while True:
        start = end + 1
        end = text.find(sep, start)
        if (end == -1) or (maxsplit == 0):
            parts.append(text[start:])
            break
        else:
            parts.append(text[start:end])
            if maxsplit != 0: maxsplit -= 1
    return parts

print(split('192.168.15.1', '.', -1))  # ['192', '168', '15', '1']
print(split('192.168.15.1', '.', 2))  # ['192', '168', '15.1']
