Python re.search()

The .search() method returns the first match of a character pattern anywhere in a given string.

Syntax

re.search(<pattern>, string, <optional args>)

A <pattern> is a regular expression that can include any of the following:

• A string: Jane
• A character class code: /w, /s , /d
• A regex symbol: $, |, ^

There are optional arguments that include the following:

• A starting index value (pos): 3
• An index value to end the search (endpos): 40
• Flags: IGNORECASE, VERBOSE, DOTALL

Note: .search() will only return the first match (as a match object) within the string; alternatively, the .findall() method matches every occurrence (and returns a list of matches).

Example

All content that appears within parentheses is matched with the .search() method in the example below:

import re

result = re.search(r"\(.*\)", "the coordinates (lat:48,lon:-120)")
# Backslashes designate a symbol as part of the pattern

print(result)
