Python Control Flow and Statements

Which keywords are used for control flow in Python?

The indentation system is not important in Python.

What is the purpose of an if statement?

In Python, control flow utilizes the keywords _____ and _____ for alternative conditions.

Match the following control flow components with their descriptions:

What keyword is used to start a conditional statement in Python?

What is the purpose of the 'elif' keyword in Python?

What does the 'else' keyword do in a conditional statement?

The indentation in Python is optional for control flow statements.

In Python, the syntax of an if statement ends with a ___

Which of the following keywords are used in Python for control flow?

Control Flow

Python uses keywords like if, elif, and else to control the flow of logic in code.
This allows specific code to execute only when a condition is met.
Example: If a dog is hungry, then feed the dog.

Indentation

The indentation system is crucial to Python and helps distinguish it from other programming languages.
Colon (:) is used to indicate the start of a code block.
The code that follows the colon must be indented to work.

if Statement

Example:

if some_condition:
    # execute some code

if-else Statement

Example:

if some_condition:
    # execute some code
else:
    # do something else

if-elif-else Statement

Example:

if some_condition:
     # execute some code
elif some_other_condition:
     # do something different
else:
     # do something else

Lecture 4: Python Statements Part 1

Control Flow is used to execute code under specific conditions
if, elif, else statements are used to control code flow based on specific conditions
Colon (:) and indentation are crucial parts of Python syntax, separating code blocks
Indentation is the use of whitespace (отступы) to clearly define code blocks
if statement executes code if a specific condition is met. Syntax:

if some_condition:
    # execute some code

else statement executes code if the condition in the if statement is not met. Syntax:

if some_condition:
    # execute some code
else:
    # do something else

elif statement allows for multiple conditions to be checked. Syntax:

if some_condition:
    # execute some code
elif some_other_condition:
    # do something different
else:
    # do something else

This quiz covers key concepts of control flow in Python, including the use of if, elif, and else statements. You will also learn about the importance of indentation and how it distinguishes Python from other programming languages. Test your understanding of these foundational programming concepts!
