Regular Expression in Python

Regular Expression is also called RE or RegEx, in short. It is a sequence of characters that forms a search pattern. It is used to check whether the search pattern exists in the given string. At first glance, It may seem complicated due to weird symbols like ^$.*± etc. But, It’s a powerful tool that is worth learning. At the end of the article, We will see some useful regex examples of real-world applications.

Python Module (re)

Python has a module named **re, **which lets you deal with the regular expressions. Many regex functionalities are residing in the module.

import re

Let us see some important functionalities of the re module.

re.findall()

It returns a list of all matching patterns.

re.findall(pattern, string)

For example:

re.search()

It returns a match object of the first location of the pattern in the string.

re.search(pattern, string)

When I was a wee lad, we used to play at Mad Libs for hours and hours. This was before computers, mind you, before televisions or radio or even paper! No, scratch that, we had paper. Anyway, the point is we only had Mad Libs to play, and we loved it! And now you must play!

We’ll write a program called mad.py  which reads a file given as a positional argument and finds all the placeholders noted in angle brackets like <verb>  or <adjective> . For each placeholder, we’ll prompt the user for the part of speech being requested like “Give me a verb” and “Give me an adjective.” (Notice that you’ll need to use the correct article.) Each value from the user replaces the placeholder in the text, and if the user says “drive” for “verb,” then <verb>  in the text replaces with drive . When all the placeholders have been replaced with inputs from the user, print out the new text.

Regular Expressions in Python [With Examples]: How to Implement?

While processing raw data from any source, extracting the right information is important so that meaningful insights can be obtained from the data. Sometimes it becomes difficult to take out the specific pattern from the data especially in the case of textual data.

The textual data consist of paragraphs of information collected via survey forms, scrapping websites, and other sources. The Channing of different string accessors with pandas functions or other custom functions can get the work done, but what if a more specific pattern needs to be obtained? Regular expressions do this job with ease.

What is a Regular Expression (RegEx)?

A regular expression is a representation of a set of characters for strings. It presents a generalized formula for a particular pattern in the strings which helps in segregating the right information from the pool of data. The expression usually consists of symbols or characters that help in forming the rule but, at first glance, it may seem weird and difficult to grasp. These symbols have associated meanings that are described here.

Meta-characters in RegEx

  1. ‘.’: is a wildcard, matches a single character (any character, but just once)
  2. ^: denotes start of the string
  3. $: denotes the end of the string
  4. [ ]: matches one of the sets of characters within [ ]
  5. [a-z]: matches one of the range of characters a,b,…,z
  6. [^abc] : matches a character that is not a,b or c.
  7. a|b: matches either a or b, where a and b are strings
  8. () : provides scoping for operators
  9. \ : enables escape for special characters (\t, \n, \b, .)
  10. \b: matches word boundary
  11. \d : any digit, equivalent to [0-9]
  12. \D: any non digit, equivalent to [^0-9]
  13. \s : any whitespace, equivalent to [ \t\n\r\f\v]
  14. \S : any non-whitespace, equivalent to [^\t\n\r\f\v]
  15. \w : any alphanumeric, equivalent to [a-zA-Z0-9_]
  16. \W : any non-alphanumeric, equivalent to [^a-zA-Z0-9_]
  17. ‘*’: matches zero or more occurrences
  18. ‘+’: matches one or more occurrences
  19. ‘?’: matches zero or one occurrence
  20. {n}: exactly n repetitions, n>=0
  21. {n,}: at least n repetitions
  22. {,n}: at most n repetitions
  23. {m,n}: at least m repetitions and at most n repetitions
