Using Comparison Operators in Python

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 help users track their physical activity. This task checks whether the user's daily step count falls within a recommended range and provides feedback on their progress.


              12345
            
daily_steps = 7500

# Step count range check
if 5000 <= daily_steps <= 10000:
    print("You're on track with your step count!")

Task

Swipe to start coding

Your task is to check whether the street temperature is in the ideal range for running. If the temperature is between 10 and 20 degrees Celsius (inclusive), print a message indicating that the conditions are optimal for running.

Use an if statement to check whether street_temperature is between 10 and 20 degrees Celsius, inclusive.
If the condition is met, assign True to running_temp; otherwise, keep it False.
Also, if hydration_goal_met is True, print a confirmation message.
