Basics of Python Programming

What is a data type in Python?

• A data type in Python is a classification that defines the type of value a variable can hold.

• A data type in Python is a method for executing functions.

• A data type in Python is a way to store files on disk.

• A data type in Python is a framework for building applications.

Name the four basic data types in Python.

• int, float, list, set

• int, float, str, bool

• char, double, list, dict

• str, bool, tuple, array

What keyword is used to define a function in Python?

• def

• method

• procedure

• function

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

• To define a function in Python.

• To execute code conditionally based on a boolean expression.

• To import modules into a Python script.

• To create a loop that iterates over a list.

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 using parentheses, e.g., my_list = (1, 2, 3).

• You create a list in Python using angle brackets, e.g., my_list = <1, 2, 3>.

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

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

• Tuples are created using square brackets, while lists use parentheses.

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

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

• Lists are faster than tuples in all operations.

What keyword is used to start a loop in Python?

• iterate

• loop

• for, while

• repeat

What does the 'break' statement do in a loop?

• The 'break' statement pauses a loop.

• The 'break' statement restarts the loop from the beginning.

• The 'break' statement exits a loop.

• The 'break' statement skips the current iteration of a loop.

How do you read input from the user in Python?

• Use the 'read()' function.

• Use the 'get_input()' function.

• Use the 'scan()' function.

• Use the 'input()' function.

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

• The purpose of the 'return' statement is to provide a value from a function to its caller.

• To define the function's parameters.

• To create a loop within the function.

• To end the function execution immediately.
