Conditional Logic Operators

Today, we'll explore how to use if-else statements with math comparison operators to make decisions in your code. This skill is crucial for music analytics, where you often need to compare values and execute different actions based on the results.

In Python, if-else statements allow you to execute certain blocks of code based on whether a condition is true or false. Think of it like a musician deciding the next note based on the current melody. The basic structure involves checking a condition and executing code accordingly:

python

Comparison operators are used to compare two values. Here are the most common ones:

  • == (equal to)

  • != (not equal to)

  • > (greater than)

  • < (less than)

  • >= (greater than or equal to)

  • <= (less than or equal to)

Imagine you're analyzing a music track and want to determine if it is a hit, a flop, or average based on its popularity score. You can use these operators to make that decision:


              
12345678

            
popularity_score = 85

if popularity_score > 80:
    print("This track is a hit!")
elif popularity_score < 50:
    print("This track is a flop.")
else:
    print("This track is average.")

You can also combine multiple conditions using logical operators like and and or to create more complex decision-making logic. For example, if you want to check if a track is both a hit and has a high energy level:


              
12345

            
popularity_score = 85
energy_level = 90

if popularity_score > 80 and energy_level > 85:
    print("This track is a high-energy hit!")
copy

Complete the categorize_length function that classifies tracks based on their duration into categories: 'Short', 'Medium', or 'Long'. This classification is useful for organizing and displaying track information in a clear and concise manner.

Inputs:

  • ms: An integer representing the duration of the track in milliseconds.

Steps:

  • Classify Duration: Use if-elif-else statements to determine the category of the track based on its duration:
    • Return "Short" if the duration is less than 180000 milliseconds (i.e., less than 3 minutes).
    • Return "Medium" if the duration is between 180000 and 300000 milliseconds (3 to 5 minutes).
    • Return "Long" if the duration is greater than 300000 milliseconds.
