NZEC ERROR

help

#1

why do i always gets an NZEC error in my python code

Traceback (most recent call last):
File “./prog.py”, line 2, in
EOFError: EOF when reading a line

i have tried raw input … map function to take input from a continous line… and even i looked that it is not an indefinite recursive call…
for every problem i submit on codechef i get the same error…
it gives error while taking the no.of testcases
