python报错

1.ValueError: unsupported format character 'D' (0x44) at index 16

string0 = "123456"
string = "string%s" %string0
上一句改成：string = "string%s".replace('%s',string0)

2.输出内容到命令行，中文字符是乱码

1>在输出内容后面加上.decode('utf-8')

 3.设定了输出的环境为utf8：

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

 4.python上配置代理出错

requests.exceptions.ConnectionError: SOCKSHTTPConnectionPool(host='myhost', port=80): 
Max retries exceeded with url: /my/path (Caused by NewConnectionError(
'<requests.packages.urllib3.contrib.socks.SOCKSConnection object at 0x106812bd0>: 
Failed to establish a new connection: [Errno 8] nodename nor servname provided, or not known',))

 

尝试将您的代理网址更改socks5://proxyhost:1234为socks5h://proxyhost:1234。注意extra h（它代表主机名解析）。
