how to take in input of every other line-CodePudding

say there was an input like so:

I tried

n = int(input())

for i in range(n):
  n, m = map(int, input().split())

but since there is a space in between it doesn't work.

CodePudding user response：

Maybe use splitlines() instead of split()

CodePudding user response：

it's probably much easier to

take inputs until the input is empty instead of asking how many there will be in advance
use a comprehension map() to collect the values (though your map works fine for me! map(int, line.split()))

collection = []
while True:
    line = input()
    if not line.strip():
        break
    collection.append([int(x) for x in line.split()])
