Python : Filtering Dictionary Keys by Value

Video 124: In this tutorial, we delve into the task of filtering dictionary keys by value. We are given a dictionary of key:value pairs and the value the user is searching for. Our objective is to filter only the keys whose corresponding value matches the user-provided value. This is a simple question designed to assess your ability to traverse a dictionary. We can tackle this task in two different ways: *** Approach 1: Simple looping option *** In this approach, we use a step-by-step process to iterate through the dictionary. We filter out the keys whose value matches the user's query. If a match is found, we add the key to the output variable and return the result. *** Approach 2: Using List Comprehension process *** This approach streamlines the process by employing list comprehension. It condenses the filtering operation into a single step. For a comprehensive understanding and hands-on demonstration, be sure to watch the entire video.
