python pass global variable to function

Certainly! In Python, you can pass global variables to a function by either directly referencing them within the function or by explicitly passing them as arguments. Let's go through both methods with code examples.
In this example, the function_using_global_variable directly references the global variable global_var without passing it as an argument. When you run this script, the function will print the value of the global variable.
In this example, the function_using_argument takes a global variable (global_var) as an argument. When you call the function and pass the global variable as an argument, it behaves similarly to the first method, providing access to the global variable within the function.
While it's possible to directly reference global variables within functions, it's generally considered better practice to pass variables explicitly as arguments. This makes the code more modular and easier to understand.
If you need to modify the global variable within the function, you need to use the global keyword inside the function. For example:
This tutorial covers the basics of passing global variables to functions in Python. Depending on your specific use case, you can choose the method that best fits your needs.
