d=a[j]-a[i]
l.append(d)
i=i=1
l.sort()
print l[0]

this is my code please help

You are trying to find all the differences, but you just need the minimum difference. sort() is your friend.

If you solve the time limit issue, you will still get “wrong answer” though, because of all the unrequested output you are generating, including input prompts which are not needed here, and debugging print-out. Be sure to clear all that away before submitting.
