Which is an example of a function header in Python?

left (40)

def drawto)

Left

def

The answer is "def".

Explanation:

In python, a function starts with the def keyword. It allows you to learn, to create and write modular Python programs using user-defined functions and it is also known as function header. It is an objective, recyclable code block, which can be called from every location in a program anytime. and other options are not correct that can be described as follows:

left (40), It is used in function calls, where left is a function name, and in the parenthesis, we pass a value in the function, that is equal to 40. def drawto), In this option, a def keyword is used to declaration function, that is "drawto" is used but there is no parenthesis is used that's why it is not correct. The left option is not correct, because it may be a variable name, a function name, etc.

That would be def.
