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)
withopen("code3.zip","wb") as code:
    code.write(r.content)
