How to get specific text from a string in regex?

To get specific text from a string using regex, you can use capture groups. Capture groups allow you to specify parts of the regex pattern that you want to extract from the string.

Here is an example of how you can extract a specific text from a string using regex and capture groups in Python:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15

import re

# Define the regex pattern with a capture group
pattern = r'hello (w+)'

# Define the input string
text = "hello world"

# Use the re.search() function to find the match
match = re.search(pattern, text)

# Extract the specific text using the group() method
if match:
    specific_text = match.group(1)
    print(specific_text)  # Output: world

In this example, the regex pattern hello (w+) is used to match the text "hello" followed by a word. The capture group (w+) matches and captures the word that follows "hello". The group(1) method is then used to extract the specific text captured by the capture group.
