Timelimt error again

#1

can this code be reduced to less time complexity
t=int(input())
for x in range(1,t+1):
n1, n2 = map(int,input().split())

for y in range(n1,n2+1):  
    if y==1:
        continue
    i=2
    while i*i<=y:
        if y%i==0:
            break;
        i=i+1
        
    else:
        print(y,end=" ")
print()

Your code is already optimised .
But still you wont be able to pass the second test case since it was made for languages such as c/c++ which are much faster than python.
So you wont be able to submit this code in python.
