Object Serialization
====================
Serializing means converting a Pyrogram object, which exists as Python class instance, to a text string that can be
easily shared and stored anywhere. Pyrogram provides two formats for serializing its objects: one good looking for
humans and another more compact for machines that is able to recover the original structures.

For Humans - str(obj)
---------------------
If you want a nicely formatted, human readable JSON representation of any object in the API you can use ``str(obj)``.
.. code-block:: python
...
async with app:
r = await app.get_chat("me")
print(str(r))
.. tip::
When using ``print()`` you don't actually need to use ``str()`` on the object because it is called automatically, we
have done that above just to show you how to explicitly convert a Pyrogram object to JSON.
For Machines - repr(obj)
------------------------
If you want to share or store objects for future references in a more compact way, you can use ``repr(obj)``. While
still pretty much readable, this format is not intended for humans. The advantage of this format is that once you
serialize your object, you can use ``eval()`` to get back the original structure; just make sure to ``import pyrogram``,
as the process requires the package to be in scope.
.. code-block:: python
import pyrogram
...
async with app:
r = await app.get_chat("me")
print(repr(r))
print(eval(repr(r)) == r) # True
.. note::
Type definitions are subject to changes between versions. You should make sure to store and load objects using the
same Pyrogram version.
