How do you know when to use : and when to use ; ?

Answer 1

I have never used ";"
":" is used when indenting, however.

Answer 2

: you use after if and loop statements. Also after derining functions

I have seen : used when there's a block of code to be written below a statement like if x < y : or else: or class tree: it identifies a block of code below them. ; is used in other languages like c after statements of code
