问题1：Missing parentheses in call to 'print'

原因:因为Python2.X和Python3.X不兼容。

我安装的是Python3.X，但是我试图运行的却是Python2.X 的代码。

所以上面的语法在python3中是错误的。在python3中，你需要将print后面的语句加括号，正确的写法：

print ("hello world")

问题2：创建项目报错，django-admin startproject sundyblog

File "c:\users\andy\appdata\local\programs\python\python35-32\lib\site-packages\django\utils\html.py", line 16, in <module>

from .html_parser import HTMLParser, HTMLParseError

File "c:\users\andy\appdata\local\programs\python\python35-32\lib\site-packages\django\utils\html_parser.py", line 12, in <module>

HTMLParseError = _html_parser.HTMLParseError

AttributeError: module 'html.parser' has no attribute 'HTMLParseError'

原因:HTMLParseError在pythons3.5已经没有了

解决方法:

方法1：将python版本回退到3.3或3.4

方法2：升级django版本

>pip3 install django==1.8 ##升级django版本

C:\Users\andy>django-admin startproject sundyblog ##再次执行，无报错
