Question

I have one simple question about throwing exeptions in re.match function

Is there a way to ‘match’ function threw an exception? Maybe some flag. If this is not possible maybe there is some other function in RE library which throw an exception when the list will be empty for example.

Example:

verify_link=re.match(".*"+str(country).lower()+"."+str(city).lower()+".*",link)

This example in some cases returns None

I am looking for a method that would throw Exception, not None
I can do this by ‘if’ statement, but mayby there is any other way

Answer 1

There is no such function(s) in Python re module. See the doc:

exception re.error

Exception raised when a string passed to one of the functions here is
not a valid regular expression (for
example, it might contain unmatched
parentheses) or when some other error
occurs during compilation or matching.
It is never an error if a string
contains no match for a pattern.
