3start = int(input("Enter start of range: "))
4end = int(input("Enter end of range: "))

6for num in range(start, end + 1):
7    if num < 2:
8        continue
9    is_prime = True
10    for i in range(2, int(num ** 0.5) + 1):
11        if num % i == 0:
12            is_prime = False
13            break
14    if is_prime:
15        print(num)

Output

Enter start of range: 1
Enter end of range: 10
2
3
5
7

What's going on

We test each number in the range for primality by checking divisibility up to its square root.
