在函数内部使用global关键字声明变量为全局变量。 在函数外部可以直接使用该变量。 下面是一个示例代码: AI检测代码解析 defset_global_variable():globalmy_variable my_variable="Hello, world!"defuse_global_variable():print(my_variable)set_global_variable()use_global_variable() 1. 2. 3. 4. 5. 6. ...
AI检测代码解析 # 定义全局变量global_var=10# 在函数中使用全局变量defuse_global_var():globalglobal_varprint("Global variable:",global_var)# 调用函数use_global_var() 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 总结 通过以上步骤,我们可以规范地定义和使用Python全局变量。首先,在程序的任意位置定义全...
Inside a function, you can’t access a global variable directly if you’ve defined local variables with the same name anywhere in the function.If you want to modify a global variable inside a function, then you need to explicitly tell Python to use the global variable rather than creating ...
Normally, when you create a variable inside a function, that variable is local, and can only be used inside that function. To create a global variable inside a function, you can use theglobalkeyword. Example If you use theglobalkeyword, the variable belongs to the global scope: ...

use_global() x =10 会报错 NameError: name'x'is not defined 优先级 函数中,有同名的全局变量和局部变量时, 优先使用局部变量。 示例如下 defuse_who(): x =5print(x) x =10use_who() 输出如下 5 3 修改全局变量 在函数外,修改全局变量很简单, ...
We cannot use a local variable outside of the function it is assigned in. If we try to do so, we’ll receive aNameErrorin return. Let’s review another example where we use the same variable name for a global variable and a local variable: ...
