Python Regex: The 5 Exclusive Examples

Image
 Regular expressions (regex) are powerful tools for pattern matching and text manipulation in Python. Here are five Python regex examples with explanations: 01 Matching a Simple Pattern import re text = "Hello, World!" pattern = r"Hello" result = re.search(pattern, text) if result:     print("Pattern found:", result.group()) Output: Output: Pattern found: Hello This example searches for the pattern "Hello" in the text and prints it when found. 02 Matching Multiple Patterns import re text = "The quick brown fox jumps over the lazy dog." patterns = [r"fox", r"dog"] for pattern in patterns:     if re.search(pattern, text):         print(f"Pattern '{pattern}' found.") Output: Pattern 'fox' found. Pattern 'dog' found. It searches for both "fox" and "dog" patterns in the text and prints when they are found. 03 Matching Any Digit   import re text = "The price of the

Here are ten Python projects along with code and possible solutions for your practice. 01. Palindrome Checker: Description: Write a function that checks if a given string is a palindrome (reads the same backward as forward). def is_palindrome(s):     s = s.lower().replace(" ", "")     return s == s[::-1] # Test the function print(is_palindrome("radar"))  # Output: True print(is_palindrome("hello"))  # Output: False 02. Word Frequency Counter: Description: Create a program that takes a text file as input and counts the frequency of each word in the file. def word_frequency(file_path):     with open(file_path, 'r') as file:         text = file.read().lower()         words = text.split()         word_count = {}         for word in words:             word_count[word] = word_count.get(word, 0) + 1     return word_count # Test the function file_path = 'sample.txt' word_count = word_frequency(file_path) print(word_count) 03.
