You can use Python's  find() method to search through a string for a pattern. The general syntax is shown below.

The input string that we'd considering to search through is denoted by the placeholder this_string. The pattern that we'd subsequent to to search for is given by the placeholder this_pattern.

In the above example, we tried searching for "Python" in "my_string". The find() method returned 18, the starting index of the pattern "Python".

In that case, you can add an optional upheaval in the method call that specifies how many occurrences of the pattern you'd later than to replace.

In the syntax shown above, n_occurrences ensures that isolated the first n occurrences of the pattern are replaced in the returned string.

As the replace() method returns a string, we see the \n characters in the output. For the \n character to introduce line breaks, we can print out the string as shown below:

Now, we target replacing a substring "JavaScript" that doesn't exist in my_string. Therefore, the returned string is same as my_string.
