Welcome to another Python 3.9 tutorial video, this video is about reading files.
Now we know how to write and append to files, we might want to learn how to read data from files. Doing this is simple, and is quite similar to writing files.

There are three main modes:
w - write to a file
a - append to file
r - read from file

Pickle:
What pickle does is that it “serializes” the object first before writing it to file. Pickling is a way to convert a python object (list, dict, etc.) into a character stream. The idea is that this character stream contains all the information necessary to reconstruct the object in another python script. So we will look at reading this data.
