python regex character classes

Regular expressions (regex) in Python provide a powerful way to search, match, and manipulate text using patterns. Character classes in regex allow you to match a set of characters, providing flexibility and conciseness in your patterns. In this tutorial, we'll explore Python regex character classes with code examples.
Character classes are enclosed in square brackets ([]) and represent a set of characters to match. For example, [abc] will match any single character 'a', 'b', or 'c'.
In this example, the regex [abc] is used to find all occurrences of 'a', 'b', or 'c' in the given text.
You can specify a range of characters using a hyphen (-) inside the square brackets. For example, [0-9] matches any digit.
Here, the regex [0-9] matches any digit in the text.
You can negate a character class by placing a caret (^) at the beginning. For example, [^0-9] matches any character that is not a digit.
In this example, the regex [^0-9] matches any character that is not a digit.
Python regex provides shorthand for common character classes:
Here, the regex \d\w\S matches a digit, followed by a word character, and then a non-whitespace character.
Character classes in Python regex provide a powerful way to specify sets of characters in your patterns. Experiment with different character classes and combinations to create precise and flexible matching patterns for your text processing needs.
