In Python’s syntax, a hash indicates the start of a comment, and all subsequent characters on the line are ignored. To quote the language reference:
A comment starts with a hash character (#) that is not part of a string literal, and ends at the end of the physical line. A comment signifies the end of the logical line unless the implicit line joining rules are invoked. Comments are ignored by the syntax; they are not tokens.
The second hash therefore has no syntactic meaning in Python itself.
However, assuming you mean this specific “Interactive Editor for Python”, one of its features is:
Matlab-style cell notation to mark code sections (by starting a line with ##).
Because the comments are not meaningful syntax, tools are free to interpret and use them how they like. Another example of this is pylint, which allows specially-formatted comments (# pylint: disable=message-name) to deactivate specific messages.
What is ## used for?
I have looked at other questions about this and the general consensus seems to be that
