Reading a line of integers in Python [duplicate]

Question

I am beginner in Python and I am solving a question at CodeChef where I have to read a line of space separated integers. This is what I am doing:

def main():

  t=int(raw_input())    #reading test-cases

  while t!=0:
    n, k=raw_input().split()    #reading a line of two space separated integers
    n, r=int(n), int(r)    #converting them into int
    list=[]
    #reading a line of space separated integers and putting them into a list
    list[-1:101]=raw_input().split()   

Now I to convert each element in the list to integer. Is there some better way to to do this? Please suggest an online resource where I can play with Python and learn tips and tricks!

Answer 1

In Python 2, you could write:

numbers = map(int, raw_input().split())

This reads a line, splits it at white spaces, and applies int() to every element of the result.

If you were using Python 3, the equivalent expression would be:

numbers = list(map(int, input().split()))

or

numbers = [int(n) for n in input().split()]

Answer 2

map(int, list) should solve your problem
