I wanna make a "Hello, (name)." function into Python by trying to make the printf function in C.

I want to turn it from this:

name = input("What's your name? ")
print(f"Hello, {name}.")

Into this:

name = input("What's your name? ")
printf("Hello, %s.", name")

I started off the function like this and I knew it wasn't going to work because of the second argument:

def printf(text, ...):
    print(text)

How can I make a properly working printf function like this?
