This script can be further improved. Here is a recommendation:

• While we can define regex patterns as seen at the start of the script, we can make our lives easier using regular expression management libraries instead. One example is the grok library, which is used to create variable names for patterns. This allows us to organize and extend patterns with ease, as we can express them by name instead of a string value. This library is used by other platforms, such as the ELK stack, for management and implementation of regular expressions.
