Python allows you to pass multiple arguments to a function.
Python
To assign a value to a global variable in a function, the global variable must be first declared in the function.
True
The value assigned to a global constant can be changed in the mainline logic.
False
One reason not to use global variables is that it makes a program hard to debug.
