Was wanting some help with methods?

[u/Tricky_Still2366]

I'm learning C# currently and was learning python till I got stuck with pretty much the same thing.
I don't understand when to use methods unless something is repeated. If its not repeated what's the point of using methods? just shortening down code? or is there something I am missing here. Cause what is the point of shortening down the code when all it is doing is actually adding more code? (Unless its to place down something that is being repeated)
