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:

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:
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:
popularity_score = 85 energy_level = 90 if popularity_score > 80 and energy_level > 85: print("This track is a high-energy hit!")

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
and300000
milliseconds (3 to 5 minutes). - Return "Long" if the duration is greater than
300000
milliseconds.
- Return "Short" if the duration is less than
