How Can I Use Unicode Property Matching in Python Regular Expressions?

Unicode Property Matching in Python Regular Expressions: A Comprehensive Guide

Unicode properties, such as character category and type, offer a powerful way to perform advanced text matching in regular expressions. While Python's default re module does not currently support explicit Unicode property matching, the regex module provides a solution.

Unicode Property Matching with the regex Module

The regex module, an alternative to Python's standard re module, enables Unicode property matching using the p{} syntax. This syntax allows you to specify a Unicode property within braces to match any character with that property.

For example, to match any lowercase letter, you can use the expression p{Ll}. Similarly, p{Zs} matches any space separator character.

Here is a complete list of supported Unicode property categories:

  • Alphabetic: p{Alpha}
  • Decimal digit: p{Digit}
  • Hexadecimal digit: p{XDigit}
  • Control character: p{Cntrl}
  • Punctuation: p{Punct}
  • Mark: p{Mark}
  • Symbol: p{Symbol}
  • Letter: p{Letter}
  • Number: p{Number}
  • Separator: p{Separator}
  • Space: p{Space}
  • Lowercase letter: p{Ll}
  • Uppercase letter: p{Lu}
