How to Check for the Presence of a Word in a String in Python Without Using the

Checking Word Presence in a String in Python

In Python, determining whether a word resides within a string can be achieved through multiple methods. While the .find() function is often employed, an alternative approach involving an if statement can be equally effective.

Consider the following syntax:

if word in mystring:
   print('success')

This code snippet utilizes the in operator to evaluate if a word exists within the string stored in mystring. If true, the message "success" is printed.

However, the code provided in the question employs the string.find() method, followed by an if statement. This approach is unnecessary because the .find() method already returns the index of the first occurrence of the word within the string, or -1 if the word is absent.

Therefore, the correct Python syntax for checking word presence in a string without the in operator would be:

if string.find(word) != -1:
    print('success')
