Understanding Python Control Structures

What is the purpose of the 'if' statement in Python?

• To import modules into a Python script.

• To create a loop that iterates over a list.

• To execute code conditionally based on a boolean expression.

• To define a function in Python.

How do you write a basic 'if' statement in Python?

• if (condition) do_something;

• if condition: do_something

• if condition do_something:

• if (condition) { do_something }

What will be the output of the following code: 'if 5 > 3: print("True")'?

• print('True')

• True

• 5 > 3

• False

Explain the use of 'elif' in an 'if' statement.

• The 'elif' statement allows for multiple conditions to be checked in an 'if' statement, providing an alternative path if the initial 'if' condition is false.

• 'elif' can only be used once in an 'if' statement.

• The 'elif' statement is a synonym for 'else' in Python.

• The 'elif' statement is used to terminate an 'if' statement early.

What is the syntax for a 'while' loop in Python?

• while condition: # code to execute

• while (condition) { code }

• for condition in range: code

• repeat until condition: code

How does a 'while' loop differ from a 'for' loop?

• A 'for' loop requires a condition to be checked after each iteration, while a 'while' loop does not.

• A 'while' loop checks the condition before each iteration, while a 'for' loop is used for a known number of iterations with initialization and increment in one line.

• A 'while' loop can only be used with numeric data types, while a 'for' loop can handle any data type.

• A 'for' loop checks the condition before each iteration, while a 'while' loop is used for a known number of iterations.

What will happen if the condition in a 'while' loop is always true?

• The program will enter an infinite loop.

• The loop will run a fixed number of times.

• The program will skip the loop entirely.

• The program will terminate immediately.

Write a simple 'while' loop that counts from 1 to 5.

• counter = 1 while counter < 5: print(counter) counter += 1

• counter = 1 while counter <= 5: print(counter) counter += 1

• counter = 0 while counter < 5: print(counter) counter += 1

• counter = 1 for i in range(1, 6): print(i)

What is the syntax for a 'for' loop in Python?

• for variable in sequence:

• for variable in (sequence)

• for (variable : sequence)

• for variable in sequence[]

How can you iterate over a list using a 'for' loop?

• for item in my_list: print(item)

• for item in my_list: item.print()

• for item in range(len(my_list)): print(my_list[item])

• for item in my_list: print(item, end='')
