How to escape strings for re.finditer?

[Weatherby,Gerard]

Regex is fine if it works for you. The critiques – “difficult to read” –are subjective. Unless the code is in a section that has been profiled to be a bottleneck, I don’t sweat performance at this level.

For me, using code that has already been written and vetted is the preferred approach to writing new code I have to test and maintain. I use an online regex tester, https://pythex.org, to get the syntax write before copying pasting it into my code.

Using str.startswith is a cool idea in this case.  But is it better than regex for performance or reliability?  Regex syntax is not a model of simplicity, but in my simple case it's not too difficult.
