In Python, you can pass a global variable to a function by explicitly including it as an argument in the function's parameter list. While global variables are accessible within functions, modifying them directly inside a function requires the use of the global keyword.

Here's an example to illustrate how to pass a global variable to a function:

Define a global variable

global_variable = 10

Function that takes a global variable as an argument

def modify_global_variable(value):
global global_variable
global_variable = value
print("Inside the function:", global_variable)

Display the global variable before calling the function

print("Before function call:", global_variable)

Call the function and pass the global variable

modify_global_variable(20)

Display the global variable after calling the function

print("After function call:", global_variable)
