The above would display the following output in the Python shell. It is also possible to use a global and local variable with the same name simultaneously. Built-in function globals() returns a dictionary object of all global variables and their respective values. Using the name of the variabl...
python 中的变量作用域(variable scope) 一般来说,python 中包含如下四种变量作用域 local:函数本地作用域 enclosed:闭包作用域 global:全局作用域 built-in:内建类型作用域 当python 解析器遇到某一个变量时,它就会以如下优先级确定这个变量定义在哪里。我们可以看出,这遵循了一种 “自发现位置开始由内到外” 的...
In Python, a variable declared outside of the function or in global scope is known as a global variable. This means that a global variable can be accessed inside or outside of the function. Let's see an example of how a global variable is created in Python. ...
