Python Regular Expression

[mweberr]

Hi, very helpful pipeline to evaluate assemblies. I have problems with understanding your wildcard contraint.
Can you please help ?
[^/\\\\] - A set of characters no slash and no backslash (escaped)

But why is it necessary to have two escaped backslashes in Python Regular Expression ?

Best, Michael

afair: In the regex itself you need to write \\ to denote the literal backslash character. And in the python string that describes the regex you also need to do that. Then you end up with \\\\ for a single backslash.
