stackexchange members. I'm just learning to write. I set myself a task a few days ago and today I completed its implementation. The task was to create a "backupper" (I was inspired just by my homework with "Byte of Python"): you specify from where and where the synchronization of all content will go. After that there is synchronization (copying, replacing and, if necessary, deleting). I would like to bring you my decision to defeat. As for me, it turned out, as for such a simple task, quite cumbersome. If anyone has any ideas for improving the code - making it more logical, elegant, and stripping away all the frills - I would be extremely grateful for any ideas and solutions! I apologize in advance for the stupidity.

I hope all is well with you by this moment... One way or another, I look forward to any criticism, comments, ideas in the comments.
Example 'left.json'
[
{
"1": "C:\\From_here"
}
]
Example 'right.json'
[
{
"1": "C:\\To_here"
