How to read an array of integers from single line of input in python3

Edit: After using Python for almost 4 years, just stumbled back on this answer and realized that the accepted answer is a much better solution.

Same can be achieved using list comprehensions:
Here is example on ideone:

arr = [int(i) for i in input().split()]

If you are using Python 2, you should use raw_input() instead.

Use map:

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

Just adding, in Python 2.x you don't need the to call list(), since map() already returns a list, but in Python 3.x "many processes that iterate over iterables return iterators themselves".

This input must be added with () i.e. parenthesis pairs to encounter the error. This works for both 3.x and 2.x Python

You can get a good reference from the following program

# The following command can take n number of inputs 
n,k=map(int, input().split(' '))
a=list(map(int,input().split(' ')))
count=0
for each in a:
    if each >= a[k-1] and each !=0:
        count+=1
print(count)
