• You declare a variable in Python by using the syntax: variable_name = value.

• declare variable_name as value

• value = variable_name

What is the purpose of an if statement?

• To declare a function that returns a value.

• To create a loop that runs multiple times.

• To define a variable in a program.

Explain the use of for loops in Python.

• For loops in Python are used to iterate over sequences or iterables, executing a block of code for each item.

• For loops are used to define functions in Python.

• For loops are used to create classes in Python.

• For loops can only iterate over numbers in Python.

What is a function in Python?

• A function in Python is a reusable block of code defined using the 'def' keyword.

• A function in Python is a type of variable.

How do you import a module in Python?

What is exception handling in Python?

• Exception handling is only for syntax errors.

• Exception handling in Python is a way to manage errors using 'try' and 'except' blocks.

• Exception handling requires the use of 'if' statements.

• Exception handling is a method to optimize code performance.

How do you create a list comprehension?

• Use the syntax: (expression, item for iterable)

• Create a list by using a loop and append method

• List comprehensions are created with curly braces {}

• Use the syntax: [expression for item in iterable if condition].

What is a dictionary comprehension?

• A way to create sets from lists in one line.

• A dictionary comprehension is a syntactic construct for creating dictionaries from iterable data in a single line.

• A function that converts strings to integers.

• A method for sorting lists in Python.

How can you handle multiple exceptions in Python?

• Catch all exceptions using 'except:' without specifying types.

• Use 'except (ExceptionType1, ExceptionType2) as e:' to catch multiple exceptions in one block.

• Use 'try-except-finally' to handle exceptions.

• Use 'if-else' statements to manage exceptions.
