Scans a Youtube channel for all available videos and prints the result in console and into an external file called "_list.txt" into the same directory where the script it is located.
It requires as input a Youtube channel ID in the form of: "https://www.youtube.com/channel/UCWr0mx597DnSGLFk1WfvSkQ" or "UCWr0mx597DnSGLFk1WfvSkQ".
It is using as dependency the "scrapetube" PIP module by dermasmid that can be installed by typing "pip install scrapetube" into console.
If you need only the videos IDs without the "https://www.youtube.com/watch?v=" part, comment the last but one line of code and uncomment the last line of code.
