Python program that read stdin and put it in array line by line

read_stdin_lines.py

import sys


def main():
    stdin_lines = []
    for line in sys.stdin:
        if line.strip() != "":
            stdin_lines.append(line.strip())

    # ... My code here ...
    
if __name__ == '__main__':
    main()

# Note, HackerRank on the other hand uses the style below:

n = int(input())
for i in range(n):
    a, b = input().strip().split(' ')
    print (int(a) + int(b))
