python中的常量和变量代码详解
局部和全局变量：
# name='lhf'
# def change_name():
# # global name
# name='帅了一比'
# print('change_name',name)
#
#
# change_name()
# print(name)
# name='lhf'
#
# def change_name():
# name1='帅了一比'
# name2='帅了一比'
# name3='帅了一比'
# print('change_name',name)
#
# change_name()
# globals
# NAME = "杠娘"
#
# def yangjian():
# # NAME = "史正文"
# global NAME
# NAME = "小东北"
# print('我要搞', NAME)
#
# def qupengfei():
# NAME = "基"
# print('我要搞', NAME)
#
# yangjian()
# qupengfei()
# NAME = "产品经理"
# def yangjian():
# # NAME = "史正文"
# global NAME # 已经声明，ＮＡＭＥ就是全局的的那个变量
# print('我要搞', NAME)
# NAME = "小东北" # 修改 全局的变量
# print('我要搞', NAME)
# def qupengfei():
# NAME = "基"
# print('我要搞', NAME)
# 如果函数的内容无global关键字，
# - 有声明局部变量
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# NAME = "自己"
# print('我要搞', NAME)
# qupengfei()
# - 无声明局部变量
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# NAME.append('XXOO')
# print('我要搞', NAME)
# qupengfei()
# 如果函数的内容有global关键字
# - 有声明局部变量
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# global NAME
# NAME = "自己"
# print('我要搞', NAME)
# qupengfei()
# 错误示例
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# NAME = "自己"
# global NAME
# print('我要搞', NAME)
# qupengfei()
# - 无声明局部变量
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# global NAME
# NAME = ["阿毛"]
# NAME.append('XXOO')
# print('我要搞', NAME)
# qupengfei()
######## 全局变量变量名大写
######## 局部变量变量名小写
# 优先读取局部变量，能读取全局变量，无法对全局变量重新赋值 NAME=“fff”，
# 但是对于可变类型，可以对内部元素进行操作
# 如果函数中有global关键字，变量本质上就是全局的那个变量，可读取可赋值 NAME=“fff”
# qupengfei()
# yangjian()
NAME = ["产品经理","廖波湿"]
# def yangjian():
# # NAME = "史正文"
# global NAME # 已经声明，ＮＡＭＥ就是全局的的那个变量
# print('我要搞', NAME)
# NAME = "小东北" # 修改 全局的变量
# print('我要搞', NAME)
# def qupengfei():
# # NAME = "aS"
# NAME.append('天扎龙')
# print('我要搞', NAME)
#
# qupengfei()
# NAME = ["产品经理","廖波湿"]
# def qupengfei():
# name = "自己"
# global NAME
# print('我要搞', NAME)
# qupengfei()
# NAME = '海风'
#
# def huangwei():
# name = "黄伟"
# print(name)
# def liuyang():
# name = "刘洋"
# print(name)
# def nulige():
# name = '沪指花'
# print(name)
# print(name)
# nulige()
# liuyang()
# print(name)
#
# huangwei()
# name = "刚娘"
#
# def weihou():
# name = "陈卓"
# def weiweihou():
# nonlocal name # nonlocal，指定上一级变量，如果没有就继续往上直到找到为止
# name = "冷静"
#
# weiweihou()
# print(name)
#
# print(name)
# weihou()
# print(name)
# 刚娘
# 冷静
# 刚娘
