Not sure what to title this, but look at the example below:
def example():
""" Good """
pass
If I were to print example.__doc__, it would display " Good ". Is it possible to create additional 'variables' like this for other purposes?

One interesting feature of Python is that functions are considered as first-class objects, allowing you to assign variables to them. For more insights on function attributes, refer to PEP-232.
def foo():
pass
foo.abc = 'abc'
print(foo.abc)
# 'abc'
You have the option to set the attribute within the function definition itself, but it will only take effect once the function has been executed at least once, as illustrated in the following example.
def foo():
foo.abc = 'abc'
print(foo.abc)
# This will raise an AttributeError as the attribute has not yet been assigned.
foo()
print(foo.abc)
# 'abc'
Another approach is to utilize a decorator for adding function attributes without requiring the function to be called first. Here's a demonstration:
def add_abc(func):
# Adds an attribute to a defined function.
func.abc = 'abc'
return func
@add_abc
def my_function():
pass
print(my_function.abc)
# 'abc'
