Year 3 - Term III CAT Basic Code Blocks

What is a variable in programming?

• A variable in programming is a symbolic name given to a value that can be changed during the program's execution.

• A variable in programming is a comment within the code

• A variable in programming is a type of function

• A variable in programming is a fixed value that cannot be changed

How do you declare a variable in Python?

• value : variable_name

• variable_name = value

• value = variable_name

• variable_name : value

What is the purpose of loops in programming?

• To slow down the program

• To confuse the programmer

• To make the code more complicated

• To execute a block of code repeatedly until a certain condition is met.

Give an example of a 'for' loop in Python.

• for item in sequence:

• for index in list(range(5)):

• for x in range(1, 5):

• for i in range(10):

What are functions used for in programming?

• Functions are used to predict the weather in programming

• Functions are used to play music in programming

• Functions are used to order food in programming

• Functions are used to encapsulate a set of instructions that can be reused multiple times throughout the code.

Define a function in Python that takes two parameters and returns their sum.

• def add(a, b): return a + b

• def sum(a, b): return a - b

• def multiply(a, b): return a * b

• def sum_two(a, b): return a + b

When do we use conditional statements in programming?

• We use conditional statements in programming when we want to execute different blocks of code based on certain conditions.

• Conditional statements are only used for decoration in code

• Conditional statements are used to confuse other programmers

• Conditional statements are used to slow down program execution

Provide an example of an 'if-else' statement in Python.

• if x < 5: print('x is less than 5')

• if x == 5: print('x is equal to 5')

• if x > 5: print('x is greater than 5') else: print('x is less than or equal to 5')

• if x != 5: print('x is not equal to 5')

What are the different data types in Python?

• integer, float, string, boolean, list, tuple, dictionary, set, None

• dict

• str

• array

• int

Explain the concept of operators in programming.

• Operators are used to create comments in code

• Operators are only used for printing output

• Operators are not necessary in programming

• Operators in programming are symbols that represent an operation or action to be performed on one or more operands. They are used to manipulate data and perform calculations.
