Using global variables in a function other than the one that created them

How can I define a global variable.

For example I have Foo1 class and Foo2 class and I want to use FooVariable in this classes as a global variable.

看到这个答案在创建它们的函数中使用全局变量

If you wanted a global variable named foo , you would just have to put global foo at the top of any function in which it is used. For example,

def do_something():
    global foo
    foo = foo + 1
    print foo

Note that Python "global" variables are only global to the module they appear in, not global to the entire program (as in some languages).
