How to get the value in a string using regex?

@jasen 

To get a specific value from a string using regular expression (regex) in Python, you can use the re module. Here is an example of how you can extract a specific value from a string using regex:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12
13
14
15
16
17

import re

# Sample string
input_string = "The price of the item is $50.99"

# Define the regex pattern to match the value
pattern = r'$([d.]+)'

# Search for the pattern in the string
match = re.search(pattern, input_string)

# If a match is found, extract the value
if match:
    value = match.group(1)
    print("Extracted value:", value)
else:
    print("Value not found")

In this example, the regex pattern r'$([d.]+)' is used to match any sequence of digits or decimals following a dollar sign in the input string. The extracted value is then printed if a match is found. You can customize the regex pattern according to the specific format of the value you want to extract.
