6.2.4 Applying subprograms:

• Subprograms improve program organization and reduce code duplication.

  True
• Procedures do not return a value
• Using subprograms reduces code duplication
• Order the steps involved in using subprograms in a larger program.

  1️⃣ Design the subprogram

  2️⃣ Define the subprogram

  3️⃣ Call the subprogram

  4️⃣ Pass data to the subprogram

  5️⃣ Return a value (if a function)
• Match the type of subprogram with its purpose:

  Functions ↔️ Compute and return a value

  Procedures ↔️ Perform actions or modify program state
• One benefit of subprograms is reduced code duplication
• Parameters allow subprograms to operate on different data
• Functions in Python are defined using the def keyword.
• The `add` function in Python returns a value when called.


  True
• Functions in Python must always return a value after execution.


  True
• What is the key difference between a function and a procedure in Python?

  Procedures do not return values
• When calling a subprogram in Python, you pass arguments
• Match the subprogram feature with its description:

  Return Value ↔️ Yes for Functions, No for Procedures

  Purpose ↔️ Compute and return values or perform actions
• What is the primary task of a function in Python?

  Compute and return a value
• A function in Python can calculate the area of a rectangle by accepting parameters such as length and width
• When calling a subprogram with parameters, you must provide the necessary arguments.


  True
• Subprograms can accept inputs called parameters
• In Python, functions and procedures are defined using the def keyword.
• Procedures in Python do not return a value
• Subprograms reduce code duplication by allowing the same code block to be used multiple times.
• Steps to call a subprogram in Python

  1️⃣ Use the subprogram's name

  2️⃣ Provide required arguments

  3️⃣ Enclose arguments in parentheses
• Calling a procedure requires capturing its return value.

  False
• Returning values from functions allows for modular design by encapsulating functionality.


  True
• Unit testing involves verifying the correctness of each subprogram in isolation.


  True
• Arguments provide the actual values for the parameters
• What is the purpose of unit testing in programming?

  Verify subprogram correctness
• Testing edge cases involves using boundary or extreme input values.

  True
• By thoroughly testing and debugging subprograms, you can identify and fix issues early in the development
• Procedures are used to perform actions or modify program state
• Why are individual subprograms easier to test and debug?

  Smaller, manageable units
• Match the parameter type with its description:

  Required Parameters ↔️ Must be provided when called

  Default Parameters ↔️ Have default values
• Default parameters can be overridden when calling the subprogram.

  True
• Procedures in Python do not have a return statement.

  True
• When calling a subprogram, you pass arguments
• Functions in Python are subprograms that return a value after execution.
• Procedures in Python do not return a value.


  True
• Steps to define a function in Python

  1️⃣ Use the `def` keyword

  2️⃣ Specify the function name

  3️⃣ Include parameters in parentheses

  4️⃣ Add a return statement if needed
• What is an example of calling a procedure in Python?

  greet("Alice")
• What can you do with the return value of a function in Python?

  Capture and use it
• Return values in Python are used to pass data back to the caller of a function.
