Once you’ve defined a global variable, you can use it from within the module itself or from within other modules in your code. You can also use global variables in your functions. However, those cases can get a bit confusing because of differences between accessing and modifying global ...
I know I should avoid using global variables in the first place due to confusion like this, but if I were to use them, is the following a valid way to go about using them? (I am trying to call the global copy of a variable created in a separate function.) AI检测代码解析 x = som...
