When I do some code tests, there are some comments below the solution function like this:
"""
:type x: int
:rtype: int
"""
x is my only input, so what does rtype stand for?

rtype: Return type. The type() function either returns the type of the object or returns a new type object based on the arguments passed.,If you need to check the type of an object, it is better to use the Python isinstance() function instead.
A Python docstring is a string used to document a Python module, class, function or method, so programmers can understand what it does without having to read the details of the implementation. Also, it is a common practice to generate online (html) documentation automatically from docstrings.
To avoid confusion:
type: Type of a parameter.
vartype: Type of a variable.
rtype: Return type.
It's the abbreviation for "return type".
See the Sphinx documentation for more information on field names and examples.
