Comparison Operators

Now, let's get into the details of what you can actually include within those conditions.

Comparison operators are useful for assessing the values of variables. Their result is always a boolean value, which can be either True or False.

You can compare complex mathematical expressions, elements of different data structures, strings, and even boolean values. As we already know how to compare numbers from previous chapters, let's explore other types of comparisons:

Example 1: Comparing strings to determine workout types


              12345
            
favorite_activity = "Yoga"
current_activity = "Running"

if favorite_activity != current_activity:
    print("This is not your favorite activity, but keep going!")

This checks if two strings are not equal (exact match, case sensitive).

Example 2: Comparing boolean values to check activity completion


              12345
            
# Check if the user completed their morning routine
morning_run_completed = True

if morning_run_completed:
    print("Great job on completing your morning run!")

This example evaluates whether a specific activity was completed (in this case, a morning run). Instead of writing if morning_run_completed == True, we use if morning_run_completed because the value of morning_run_completed is already a boolean (True or False). Writing == True is redundant and less concise. Python allows such simplifications to make the code cleaner and easier to read.

Example 3: Checking if a number falls within a range

Your app can even provide weather-based recommendations. This example checks if the street temperature is ideal for running and gives timely suggestions to users.


              1234
            
street_temperature = 15

if 10 <= street_temperature <= 20:
    print("Best conditions for running now!")

You are building a basic fitness tracker. Your task is to write code that checks various conditions and provides personalized feedback based on the user's activities. This will test your understanding of comparison operators.

Check if the user's steps are in the range of 5,000 to 10,000 and print: "You're on track with your step count!" (use less than or equal operator).
Add a boolean variable hydration_goal_met and use it to check if the hydration goal was met. Print a congratulatory message if true.
