Can I use default values based on previously passed positional arguments?

Question

Is it possible to use a default variable based on previously passed positional arguments?

I'm trying to do something similar:

def ex(a, b=a+1):
    return a+b

Fun fact: The `a` in `b=a+1` would be a global variable in existence at the point the function is defined, not the like named parameter `a` in the function definition. — tdelaney, Oct 25 '22 at 16:56

You can do that inside of the body, but not the signature.

def ex(a, b=None):
    if b is None:
       b=a+1
    return a+b
