Explain what you believe this operation is doing, show us the input and
the output.
The best I can make out of that is that it is looking for single quote
characters within whatever "a" is, and replacing them with nothing.
Something much more understandable, without invoking a regular expression
library (especially when neither the search nor the replacement terms are
regular expressions) with simple string operations...
stripped = "".join(quoted.split("'"))
Whether that's easier to understand it very much in the eye of the
beholder.
As it's just a simple replacement, I would've thought that the 'obvious'
solution would be:
a = a.replace("'", "")
