Earlier I was taking range starting from 2 to half of the value. Now that I am taking from 2 to value. Still, it is showing It’s wrong. Could someone please tell me where I am making mistake?

You have not accounted for the test case where the value of N = 1 which should return false since 1 is not a prime number.
Also, your logic is quite confusing, you can simplify it like my code:

def isPrime(n): 
  
    # The case you forgot to add
    if n == 1: 
        return False
  
    for i in range(2, n): 
        if n % i == 0: 
            return False; 
  
    return True

t = int(input())

for _ in range(t):
    n = int(input())
    if(isPrime(n)):
        print("yes")
    else:
        print('no')
