🧹 Clean code refactor

[josehenriqueroveda]

Please refactor the code to follow these good practices:

• [x] Set directories names within the project to lowercase
• [x] In DNS_Tools/modules fix the name inputpy.py to just input.py
• [x] Consider only Python 3 in your project
• [x] Remove obvious comments from code and use docstrings in functions
• [ ] Change the name of the functions to more explanatory names
• [x] Keep all variables names in English and lowercase
• [ ] Make the script executable via the command line with dynamic parameters, for example (--file for the name of the .txt file)

In the task Change the name of the functions to more explanatory names take a look at How to write meaningful variable names

And for the last task, to make it an CLI application, you can use the Typer lib.
