Escape Sequences

Escape sequences allow you to include special characters in your regex patterns. Here are some common escape sequences:

• \d: Matches any digit (equivalent to [0-9]).
• \D: Matches any non-digit character (equivalent to [^0-9]).
• \w: Matches any word character (equivalent to [a-zA-Z0-9_]).
• \W: Matches any non-word character (equivalent to [^a-zA-Z0-9_]).
• \s: Matches any whitespace character (equivalent to [ \t\n\r\f\v]).
• \S: Matches any non-whitespace character (equivalent to [^ \t\n\r\f\v]).

import re

text = "The price is $5.99 on 06/12/2024."
pattern = r"\d{2}/\d{2}/\d{4}"
matches = re.findall(pattern, text)

print(matches)  # Output: ['06/12/2024']

In the above example, the pattern \d{2}/\d{2}/\d{4} matches a date in the format "MM/DD/YYYY". The \d escape sequence matches any digit.
