NZEC in CANDY III

[coder05]

import fractions
t_int=int(input())
for num in range(1,t_int+1):
    x=0
    n=int(input())
    for num in range(n):
        a_str=input()
        a=int(a_str)
        x=x+a
    x=x/n
    a=fractions.Fraction(x)
    if ((a.denominator==1)):
        print('YES')
    else:
        print('NO')

Getting NZEC with this code .. plz help anyone

Doesn't input read a whole line? How does it handle blank lines like the one in the input? Would n then be zero? This would cause divide by zero which would return an NZEC.

Yeah... now i added another line of input so that it accepts empty lines.. but now it shows WA ...
whats wrong now!!

Do you really need to use a fraction? Can't you think of a simpler way to perform that function? You have num assigned in two different spots, does python understand that?

[coder05]

yeah.. num assigned n two different places does not interfere... nyways... the result does not change even after changing one of the num

Focus on the first part of my previous post.
