1. Ch 6 problem 10

2. Modify our firstprimes method discussed in class (included below) to print
out all the prime numbers less than or equal to the input parameter, num.

def firstprimes(num):
    """Prints out the first num primes"""
    count = 0  # the number of primes we've printed out
    current = 1  # the current number we're checking
        
    while count < num:
        if isprime(current):
            print current
            count += 1
        
        current += 1
