Need help to make an empty function

Question

I want to make a function pi(d), where "d" tells how many decimals pi should return. If "d" is bigger than 15, it should include 15 decimals. If "d" is empty(pi(d)), pi should include 2 decimals. I have tried:

import math

def pi(x):
    if x>15:
        print(math.pi)
    elif x=="":
        print(round(math.pi, 2))
    else:
        print(round(math.pi, x))

What is wrong?

By empty, do you mean *omitted*, as in `pi()`? It might help if you include the complete text of your assignment in your question. — Mark Plotnick, Sep 23 '19 at 12:15

i mean omitted

So, you mean: How do I create a Python function with optional arguments?

In your case:

def pi(x=2):
    if x>15:
        print(math.pi)
    else:
        print(round(math.pi, x))

pi()
