What are the regular expressions in Python?
Regular Expression Syntax. A regular expression (or RE) specifies a set of strings that matches it; the functions in this module let you check if a particular string matches a given regular expression (or if a given regular expression matches a particular string, which comes down to the same thing).
How do you write regular expressions in Python?
Python has a module named re to work with RegEx. Here's an example: import re pattern = '^a...s$' test_string = 'abyss' result = re.match(pattern, test_string) if result: print("Search successful.") else: print("Search unsuccessful.")
A regular expression is a special sequence of characters that helps you match or find other strings or sets of strings, using a specialized syntax held in a pattern. Regular expressions are widely used in the UNIX world.
The Python module re provides full support for Perl-like regular expressions in Python. The re module raises the exception re. error if an error occurs while compiling or using a regular expression.
We would cover two important functions, which would be used to handle regular expressions. But a small thing first: There are various characters, which would have special meaning when they are used in the regular expression. To avoid any confusion while dealing with regular expressions, we would use Raw Strings as an expression.
