python下载文件的几种常用方法

python中下载文件常用的几个模块有urllib，urllib2，requests，方法也很简单，代码如下：

# Python 2 code
import urllib
import urllib2
import requests

url = 'http://192.168.1.100/test.zip'

print "downloading with urllib"
urllib.urlretrieve(url, "code.zip")

print "downloading with urllib2"
f = urllib2.urlopen(url)
data = f.read()
with open("code2.zip", "wb") as code:
code.write(data)

print "downloading with requests"
r = requests.get(url)
with open("code3.zip", "wb") as code:
code.write(r.content)
