print 'python模块操作'

#导入一个模块，通过模块.方法使用
import demo7
demo7.plus(100)

#将模块的某部分添加到当前模块字典中，使用时无需声明所属模块
from demo7 import plus
plus(100)

#将math模块的所有内容加入当前模块
from math import *
print abs(-100)

#列出模块中所有内容的列表
print dir()

ok = 'ok'
def getDict():
    key = 'name'
    print globals()#得到函数中可访问的全局变量
    print locals()#得到函数中可访问的局部变量
getDict()

#重新加载模块（模块的可执行代码会再次执行）
reload(demo7)

输出：
