如何使全局变量与 Python 中的 Pycharm 一起使用？

Question

Pycharm global variables do not seem to work. Any suggestions?

def func():
   global a 
   print(a)

'a' is not defined I get.

But, this works fine in Python notebook. Of course I checked and 'a' is in globals() in both python notebook and pycharm. Any tips to resolve this, or if not optimal alternatives will suffice

I cannot modify the function to take a as an argument, but it needs to be of a specific structure for another package.

Answer 1

That's because the variable a is not defined. Try with:

 def func():
   global a 
   a = 1 #for example
   print(a)

The output will be:

>>> 1

Answer 2

Maybe you don't have it in that file. Have it imported from wherever it was declared and then do the same as you already did.
