What is the difference between a list and a tuple in Python?

• Lists can contain only numbers while tuples can contain any data type.

• Tuples are faster than lists because they use more memory.

• Lists are defined using parentheses while tuples are defined using square brackets.

• The main difference is that lists are mutable and tuples are immutable.

How can you import a module in Python?

• Use the 'require' statement, e.g., 'require(module_name)'

• Import modules using 'load module_name'

• You can import a module by typing 'include module_name'

• Use the 'import' statement, e.g., 'import module_name'.

What is the purpose of the 'return' statement in a function?

• To exit a function and return a value to the caller.

• To pause the function execution temporarily.

• To define a function's parameters.

• To create a loop within the function.

Explain the concept of mutable and immutable data types in Python.

• Both mutable and immutable data types in Python are represented by the same data structures.

• Immutable data types in Python include sets and arrays, while mutable data types include tuples and strings.

• Mutable data types in Python include lists and dictionaries, while immutable data types include tuples and strings.

• Mutable data types include strings and tuples, while immutable data types include lists and dictionaries.

How do you create a dictionary in Python?

• Use square brackets with key-value pairs, e.g., ['key': 'value'].

• Create a dictionary using parentheses, e.g., ('key', 'value').

• Define a dictionary by listing keys and values in a single string, e.g., 'key: value'

• Use curly braces with key-value pairs, e.g., {'key': 'value'}.

What is a lambda function in Python?

• A lambda function is a function that can only take one argument.

• A lambda function is an anonymous function defined with the 'lambda' keyword.

• A lambda function is a type of loop in Python.

• A lambda function is a built-in function that returns a value.

How can you handle exceptions in Python?

• Use print statements to debug errors.

• Ignore exceptions and continue execution.

• Always restart the program when an error occurs.

• Use try-except blocks to handle exceptions.

What is the significance of the '__name__' variable in a Python script?

• The '__name__' variable stores the version of Python being used.

• The '__name__' variable helps determine if a Python script is being run directly or imported as a module.

• The '__name__' variable is used to define global variables in a script.

• The '__name__' variable is a built-in function that returns the script's file path.
