a good explanation

[mik3]

wow!...thanks for both replies..and yes you are right, he comes from a
world of C and java...i have successfully "brainwashed" him to try out
coding in python...haha.
So he has written his first program in python and i have roughly toook
a glance at it and saw what he did.. i pointed out his "mistakes" but
couldn't convince him otherwise. Anyway , i am going to show him your
replies..
thanks again.
