How to traverse all folders and files within a folder dynamically in Python 3

I had this requirement where I need to be able to look into a folder and pick up any configuration files for my Python 3 application. In order to achieve that, I first set an exploratory task to get the Python 3 code for traversing all folders and files within a folder.

For this exploratory task, I had created a script that will traverse the folders and files that are contained within a folder and print out their full paths.

How to save and load objects to and from file in C#

Persistency is almost always a requirement for applications that are meant for serious usage. Perhaps we want the data that our C# program had harvested or generated to be available everytime it runs. Or for that load of data that we are unable to send to a server to be remembered, so that we can try sending at a later time.

Because most of the data that is held by a C# application at runtime is in the form of objects, it is convenient to be able to save and load objects to file directly. Such capability is dubbed object serialization, and like many other programming languages, C# has the facilities to perform object serialization for developers.

How to read from file in C#

The ability to read from file gives our C# programs the ability to act on data given by other programs, which may be written in different programming languages.

Such a ability is also helpful in allowing humans to configure how our C# program will behave at runtime.

Since being able to read from file is so helpful in C#, I want to remember how I can do that with this post.
