Python REGEX How to extract particular numbers from variable
Download this code from https://codegive.com
Regular expressions (regex) in Python provide a powerful way to search for and extract specific patterns from strings. In this tutorial, you'll learn how to use Python's re module to extract particular numbers from a variable using regex.
Make sure you have Python installed on your system. Python comes with the re module by default, so no additional installations are needed.
Import the re module:
Start by importing the re module, which provides support for working with regular expressions in Python.
Define the String Containing Numbers:
Create a string variable containing the text from which you want to extract specific numbers.
Create a Regex Pattern:
Define a regex pattern that matches the specific numbers you want to extract. For example, to extract all integers and floating-point numbers, the pattern might look like this:
Use re.findall() to Extract Numbers:
Apply the regex pattern using the re.findall() function to extract all matches from the text.
Display the Extracted Numbers:
Iterate through the extracted numbers list to display the matched numbers.
Here's the complete code combining all the steps described above:
This example demonstrates how to extract integers and floating-point numbers from a string using a regular expression pattern in Python.
Feel free to modify the regex pattern to match different number formats or adjust the text to test different scenarios for extracting specific numbers based on your requirements.
