Pre-Compile the RegEx functions

[Fujio-Turner]

Log Parsing:

• Regular Expressions: If you're parsing log lines, using regex can be efficient but ensure you compile them outside of loops for performance.

import re
log_pattern = re.compile(r'^\[(.*?)\] (\w+) (.*)')

for line in log_file:
    match = log_pattern.match(line)
    if match:
        timestamp, level, message = match.groups()
        # Process log entry

• String Methods: For simple parsing, string methods like split() might be faster than regex for certain patterns.
