在最后一个print语句中,我们证明了主块中的x的值确实没有受到影响 global语句 如果你想要为一个定义在函数外的变量赋值,那么你就得告诉Python这个变量名不是局部的, 而是 全局 的。我们使用global语句完成这一功能。没有global语句,是不可能为定义在函数外 的变量赋值的,使用global语句可以清楚地表明变量是在外面的...

Why does this work? Because this will define the variable inside the function's scope. It will no longer go to the surrounding (global) scope to look up the variables value but will create a local variable that stores the value of x at that point in time.funcs = [] for x in range...
1.通过Global内变量__name__进行判断2.当以python mod.py运行脚本时__name__变量为__main__字符串3.当以模块导入时__name__为模块名称字符串 包将不同模块文件放在不同文件夹内,包文件夹下面需要有__init__.py文件用以声明该文件为Python包。使用时需要从包内导入模块后调用模块中变量和函数。 常用系统...
