Pass a list to a function to act as multiple arguments in python

Pass a list to a function to act as multiple arguments in python

In Python, you can pass a list to a function and have its elements act as multiple arguments using the * operator in the function call. This is known as "unpacking" the list. Here's how you can do it:

def my_function(arg1, arg2, arg3): print(f"arg1: {arg1}") print(f"arg2: {arg2}") print(f"arg3: {arg3}") my_list = [1, 2, 3] # Call the function with elements of the list as separate arguments my_function(*my_list)

In this example:

  1. We define a function my_function that takes three arguments.

  2. We create a list called my_list with three elements.

  3. When calling my_function, we use the * operator before my_list to unpack its elements and pass them as separate arguments to the function.

As a result, the elements of my_list (1, 2, and 3) are passed to my_function as arg1, arg2, and arg3, respectively. When you run this code, it will print:

arg1: 1 arg2: 2 arg3: 3

This technique is useful when you have a list of values that you want to pass as arguments to a function without explicitly specifying each argument one by one.
