Answer 1

You can print a variable. decorated is a variable that contains a method (decor(func), where func=print_text). So, it is callable:

>>> type(decorated)
<class 'function'>
>>> print(decorated)
<function wrap at 0x02EDCDF8>
>>> decorated() # the same as decor(print_text)
============
Hello world!
============

Methods like this are called decorators. You can also use it like this:

@decor
def print_text():
print("Hello world!")

>>> print_text()
============
Hello world!
============
