To find first N prime numbers in python

Question

I am new to the programming world. I was just writing this code in python to generate N prime numbers. User should input the value for N which is the total number of prime n

Answer 1

This might help:

import sys
from time import time
def prime(N):
    M=100
    l=[]
    while len(l) < N:
        for i in range(M-100,M):    
            num = filter(lambda y :i % y == 0,(y for y in range(2 ,(i/2)))) 
            if not num and i not in [0,1,4]:
                l.append(i)
        M +=100
    return l[:N]


def dotime(func, n):
    print func.__name__
    start = time()
    print sorted(list(func(n))),len(list(func(n)))
    print 'Time in seconds: ' + str(time() - start)


if __name__ == "__main__":
    dotime(prime, int(sys.argv[1]))
