python-regexHow to do an exact match with regex in Python?

To do an exact match with regex in Python, you can use the re.match() function. This function takes a regular expression pattern and a string as arguments and returns a match object if there is a match.

Example code

import re

pattern = r"Hello"
string = "Hello World"

match = re.match(pattern, string)

if match:
  print("Match found:", match.group())
else:
  print("No match found")

Output example

Match found: Hello

Code explanation

• import re: imports the re module which contains the re.match() function
• pattern = r"Hello": defines the regular expression pattern to match
• string = "Hello World": defines the string to match against
• match = re.match(pattern, string): calls the re.match() function with the pattern and string as arguments
• if match:: checks if a match was found
• print("Match found:", match.group()): prints the matched string
• else:: runs if no match was found
• print("No match found"): prints a message if no match was found
