Python 2.7.8 学习笔记（003）python manuals/the python tutorial -- 2. Using the Python Interpreter

添加c:\python27到环境变量path

python -c command [arg] ..., 

python -m module [arg] ..., 

 参数传递：the argv variable in the sys module

>>>    //交互模式

用缩进表示语句块，可真不习惯

>>> the_world_is_flat = 1
>>> if the_world_is_flat:
...     print "Be careful not to fall off!"
...
Be careful not to fall off!

print语句前的缩进不可少
