How to read first set of numbers between strings using regex?

To read the first set of numbers between strings using regex, you can use a regular expression pattern to match the numbers. Here is an example of how you can do this in Python:

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

import re

# Sample string
text = "The first set of numbers is 12345 and the second set is 67890"

# Define a regular expression pattern to match the first set of numbers
pattern = r'(d+)'

# Use the re.findall() function to find all matches of the pattern in the text
matches = re.findall(pattern, text)

# Get the first match (which corresponds to the first set of numbers)
if matches:
    first_set = matches[0]
    print("First set of numbers:", first_set)

In this example, the regular expression pattern (d+) is used to match any sequence of digits between word boundaries. The re.findall() function is then used to find all matches of this pattern in the input text. The first match is then extracted and printed as the first set of numbers.

You can modify the regular expression pattern to suit the specific format of the input text or the requirement of your task.
