Program 22

                                             Program 22

Write a function called primes that is given a number n and returns a list of the first n primes. Let the default value of n be 100.

def printPrime(n=100):
    l=[]
    x=2
    while(len(l)<n):    
        for i in range(2,int(x**0.5)+1):
            if(x%i==0):
                break
        else:
            l.append(x)
        x=x+1
    return(l)
n=int(input("enter the number of prime numbers:")) 
s=printPrime(n)
print("List of first",n,"primes:",s)
j=printPrime()
print("List of first 100 primes:",j)

      OUTPUT:
