You can solve this using a while loop to repeatedly find and remove the target substring until it no longer exists in the word. : This method returns the starting index of

: The while True ensures the code keeps searching until every instance is gone, which is necessary if the letter appears multiple times (e.g., removing "na" from "banana"). Alternative (Standard Python) Copied to clipboard You can solve this using

While the CodeHS exercise often requires the manual loop approach above, the simplest way to do this in standard Python is using the .replace() method:

The prompt likely refers to from the CodeHS Python curriculum. This exercise requires you to write a function that removes every instance of a specific "letter" (or substring) from a given word. Correct Python Implementation
