PY Euler sieve

Big Data with python? Speed ​​moving

Enter 1e7 then suddenly came out of python Euler screen, tune for a long time

A solution after a few seconds,PY really rapidly

PY can never learned as a student to read the VB program, anyway, almost isolated language [fog

Code

import os
import ssl
import urllib
import time
import re
import urllib

def getPrime(n):
    v=[0 for i in range(n+1)]
    p=[]
    for i in range(2,n):
        if v[i]==0:
            p.append(i)
#            print(i)
        for j in p:
            if i*j>n:
                break
            v[i*j]=1
            if i%j==0:
                break
    return p


while 1:
    n=input()
    try:
        n=int(n)
    except:
        break
    f=open('F:\\PY\\List.txt','w')
    for i in getPrime(n):
        f.write(str(i)+' ')
    f.close()

So, the same principles, the same wording, PY why slow so good?
