I am facing a problem that I can’t be able to take input in any of python
program even it is submitted previously by other user successfully.
code :
T = int(input())
for tc in range(T):
(a, b) = map(int, input().split(’ '))
ans = a + b
print(ans)

while using custom input ,it is running successfully but in test cases, It
is showing following error:-
Runtime Error :
NZEC

Error:
Traceback (most recent call last):
File “./prog.py”, line 5, in
EOFError: EOF when reading a line

My codechef coding test is on 25th july 2019 in my institute,but due to
this problem my practice is totally stopped. Please help me to resolve this
issue.Screenshot_20190723_101021

You can use This

for t in range (int(input())):
   a,b = map(int,input().split())
