Question

How do you match only equal numbers of the same character (up to 3) on each side of a string in python?

For example, let’s say I am trying to match equal signs

=abc= or ==abc== or ===abc===

but not

=abc== or ==abc=

etc.

I figured out how to do each individual case, but can’t seem to get all of them.

(={1}(?=abc={1}))abc(={1})

as | of the same character

((={1}(?=abc={1}))|(={2}(?=abc={2})))abc(={1}|={2})

doesn’t seem to work.

Use the following regex:

^(=+)abc\1$

Edit:

If you are talking about only max three =

^(={1,3})abc\1$
