How do you create a list in Python?

• You create a list in Python using curly braces, e.g., my_list = {1, 2, 3}.

• You create a list in Python by using the list() function, e.g., my_list = list(1, 2, 3).

• You create a list in Python using square brackets, e.g., my_list = [1, 2, 3].

• You create a list in Python using parentheses, e.g., my_list = (1, 2, 3).

What is the purpose of an if statement in Python?

• To execute code conditionally based on a boolean expression.

• To repeat code multiple times.

• To create a loop for iteration.

• To define a function in Python.

Explain the use of for loops in Python.

• For loops in Python are primarily used for error handling.

• For loops can only iterate over numbers in Python.

• For loops in Python are used to define functions.

• For loops in Python allow iteration over sequences and execute a block of code for each item.

What is a function in Python and how is it defined?

• A function in Python is defined using the 'func' keyword.

• A function in Python is defined using the 'def' keyword, followed by the function name and parentheses.

• A function in Python is defined by writing the function name followed by a colon.

• Functions in Python are created with the 'create' keyword.

How can you import a module in Python?

• You can import a module by copying its code directly into your script.

• Use the 'require' statement to load the module.

• Modules can only be imported from the current directory.

• Use the 'import' statement followed by the module name.

What is the purpose of the open() function in file handling?

• To open a file and return a file object for file handling operations.

• To create a new file without opening it.

• To delete a file from the system.

• To read the contents of a file into memory.

How do you read a file line by line in Python?

• Use 'with open(filename, 'r') as file: for line in file: process(line)'.

• Use 'open(filename, 'w') as file: file.write(line)'

• Use 'file.read_lines(filename)'

• Use 'open(filename) as file: for line in file: read(line)'

What is exception handling in Python?

• Errors in Python cannot be caught or handled.

• Exception handling in Python is done using 'if' statements.

• Exception handling in Python is done using 'try' and 'except' blocks to catch and handle errors.

• Python uses 'try' and 'finally' blocks exclusively for exception handling.

How do you raise an exception in Python?

• raise ExceptionType('Error message')

• raise ExceptionType()

• raise 'Error message'

• throw ExceptionType('Error message')
