[Python] how to take a file as input stream in Python

I have this piece of code:

t=int(input())
for i in range(t):
n,k=map(int, raw_input().split())
A=map(int, raw_input().split())
B=map(int, raw_input().split())
A.sort()
B.sort(reverse=True)
flag=True
while(i<len(A)):
if A+B<k:
flag=False
break
i+=1
if flag==True:
print "YES"
else:
print "NO"


And I want to give a text file containing the following data formatted specifically to be given input to such a program. How should I do it? here is the text:

10
8 91
18 73 55 59 37 13 1 33
