What is a procedure?
A block of code that performs a specific task; also known as methods or functions.
What is a parameter?
A variable listed in a procedure's definition that acts as a placeholder for input values.
What is an argument?
The actual value passed to a procedure when it is called.
What is a return value?
The result a procedure sends back after it has finished executing.
What is the purpose of the RETURN statement?
To send a value back from a procedure to the calling code and to stop the procedure's execution.
Define reusability in programming.
The ability to use a block of code (like a procedure) multiple times without rewriting it.
What is a method?
Another name for a procedure, often used in object-oriented programming.
What is a function?
Another name for a procedure, a block of organized, reusable code.
What is a local variable?
A variable defined inside a procedure, accessible only within that procedure.
What does it mean to call a procedure?
To execute the code contained within the procedure.
What does the following code output?
python
def my_procedure(x):
return x * 2
print(my_procedure(5))

What does the following code output?
python
def greet(name):
print("Hello, " + name)
greet("Alice")
print(greet("Bob"))
Hello, Alice Hello, Bob None
Identify the error in the following code:
python
def add(x, y):
print(x + y)
result = add(3, 4) + 5
print(result)
TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'. The add function prints the sum but does not return a value, so result becomes None.
What does the following code output?
python
def calculate(x, y):
z = x * y
return z
result = calculate(4, 5)
print(result + 2)

What does the following code output?
python
def my_func(a, b):
a = a + 10
return a + b
x = 5
y = 2
print(my_func(x, y))
print(x)

Identify the error in the following code:
python
def square(x):
return x * x
print(square)
The code will print the function object itself, not the result of the function. To see the result, you need to call the function with an argument, e.g., print(square(5)).
What does the following code output?
python
def greet(name):
return "Hello, " + name + "!"
message = greet("Charlie")
print(message)
Hello, Charlie!
What does the following code output?
python
def combine(str1, str2):
result = str1 + " " + str2
return result
print(combine("Open", "AI"))

Identify the error in the following code:
python
def divide(x, y):
return x / y
print(divide(10, 0))
ZeroDivisionError: division by zero. Dividing by zero is mathematically undefined and will cause a runtime error.
What does the following code output?
python
def outer_function(x):
def inner_function(y):
return x + y
return inner_function(5)
print(outer_function(10))

How are procedures applied in real-world scenarios?
Procedures are used in virtually every software application to organize code, perform specific tasks, and avoid code duplication. Examples include functions for calculating taxes, processing user input, and rendering graphics.
