here x is a local variable, it is visible just in the function of fun(). It has no relationship with the x variable outside. ''' x=10 deffun(): x=10000 print(x) fun() print(x) # In[] ''' result: UnboundLocalError: local variable 'x' referenced before assignment you can do ...
A global variable in Python is a variable defined at the module level, accessible throughout the program. Accessing and modifying global variables inside Python functions can be achieved using the global keyword or the globals() function. Python handles name conflicts by searching scopes from local...
