Using dict with parameter

Question

Is it possible to use a function with a dict argument which has other argument like p2 in it?

def f(l, p2, p = {"t": p2}):
    print(l)

f(12, 13)

Traceback (most recent call last): File "", line 1, in NameError: name 'p2' is not defined — Karen William, Jun 15 '22 at 12:09
Hi Karen, dont be sorry for asking questions, its what SO is for. That being said what are you trying to do? why not define `p` in the function. You need to explain what you are trying to do, what you expect output to be, and what the problem is. — Craicerjack, Jun 15 '22 at 12:11

No. The dict {"t": p2} is created at function definition, at which time p2 is not bound to anything.

What you can do is

def f(l, p2, p=None):
    if p is None:
        p = {'t': p2}

    # rest of code
