Скачать или смотреть Match on specific words in a text file using regex using python

Regular expressions, or regex, are a powerful tool for pattern matching and text processing in Python. In this tutorial, we will explore how to match specific words in a text file using regex in Python. We will cover the following topics:
First, you need to import the re module, which provides the functionality for working with regular expressions in Python.
Before you can match specific words in a text file, you need to read the content of the file. You can do this using Python's built-in file handling.
Regex patterns allow you to describe the specific words you want to match. Here are some common regex components:
Let's say we want to find all occurrences of the word "apple" in our text file. Here's how you can use regex to achieve that:
In this example, we use the re.findall() function to find all occurrences of the word "apple" in the text file. The \b characters are word boundaries, ensuring that we match whole words and not substrings. We also use re.IGNORECASE to make the matching case-insensitive.
Replace "sample.txt" with the path to your text file, and "apple" with the word you want to search for.
This tutorial demonstrates how to match specific words in a text file using regex in Python. With this knowledge, you can adapt the code to match other words or more complex patterns in your text files.
