def fact(x):     f=1     while x>0:         f=f*x         x-=1     return f t=int(raw_input('')) while t>0:     n=int(raw_input(''))     r=int(raw_input(''))     ans=fact(n)/(fact(r)*fact(n-r))     print str(ans) + "\n"      t-=1

n , r entered on same line.

100 10

your program expects them entered on 2 separate lines.

100 10
