Is a Word Present in a String?: A Python Guide

How to Determine if a Word is Present within a String in Python

In Python, there are multiple methods to ascertain whether a specific word exists within a given string. One approach involves utilizing the .find() function, which returns the starting index of the first occurrence of the word. However, for simplicity and ease of implementation, a more direct method is to employ an if statement.

Using an if Statement to Check for Word Presence

The following code snippet demonstrates how to leverage an if statement to check if a word is present within a string:

mystring = "Hello, world!"
word = "world"

if word in mystring:
    print('success')

Simplifying the Code

The above code snippet can be simplified further by removing the need for an explicit check for truthiness. This can be achieved by directly printing the word:

mystring = "Hello, world!"
word = "world"

if word in mystring:
    print(word)

This will result in the word "world" being printed to the console, indicating its presence within the string.
