Ten minutes cording

I challenged Ten minutes cording. This site,

１０分でコーディング｜プログラミングに自信があるやつこい！！

"If you had exceeded ten minutes to write it. You can not program very"

But, I had taken about fifty minutes...
I feel to need it what more learn about Algorithm. And more faster typing.

Wrote by python.

# -*- coding: utf-8 -*-

def card(play,num):
    lis = []
    stat = 0
    end = len(num) / play
    for i in range(play):
        lis.append(num[stat:stat + end])
        stat = stat + end
    return lis

if __name__=='__main__':
  print card(3,"123123123")
