How Can I Pass a Variable Number of Arguments to Python Functions?

Passing Variable Arguments to Functions in Python

Unlike in languages such as C or C, functions in Python traditionally accept a fixed number of arguments. However, you can achieve something similar to variable argument lists using the *args syntax.

Non-Keyword Arguments: Using *args

For non-keyword arguments, you can utilize *args as the argument placeholder. This allows you to accept any number of arguments as a tuple.

def manyArgs(*args):
  print("I was called with", len(args), "arguments:", args)

>>> manyArgs(1)
I was called with 1 arguments: (1,)
>>> manyArgs(1, 2, 3)
I was called with 3 arguments: (1, 2, 3)
Copy after login

As demonstrated in the example, Python unpacks the arguments into a tuple, conveniently available for processing.

Keyword Arguments: Separate Actual Arguments

For keyword arguments, you need to accept them as separate actual arguments. For instance, the following function accepts two keyword arguments, x and y, followed by variable non-keyword arguments via *args:

def myFunc(x, y, *args):
  pass
Copy after login

This approach allows you to combine fixed and variable arguments in a single function signature.
