What are the basic data types in Python?

• int, float, str, bool, array, dict

• int, float, str, bool, list, tuple, set, dict

• int, float, str, boolean, list

• char, float, array, dict

How do you declare a variable in Python?

• variable_name : value

• declare variable_name as value

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

• value = variable_name

What is the difference between a list and a tuple?

• A list is mutable; a tuple is immutable.

• A list can only contain numbers; a tuple can contain any data type.

• A list is defined by square brackets; a tuple is defined by curly braces.

• A list is faster than a tuple for data retrieval.

How do you convert a string to an integer in Python?

• Use eval('string') to get an integer from a string.

• Apply float('string') for conversion to integer.

• Use str('string') to convert a string to an integer.

• Use int('string') to convert a string to an integer.

What is a control structure in programming?

• A control structure is a programming construct that controls the flow of execution in a program.

• A control structure is a type of variable in programming.

• A control structure is a method for storing data in a program.

• A control structure is a way to define functions in programming.

Explain the use of 'if' statements in Python.

• 'if' statements are only for looping through lists in Python.

• 'if' statements in Python are used for conditional execution of code blocks.

• 'if' statements are used to define functions in Python.

• 'if' statements are used to declare variables in Python.

What is a loop, and how is it used in Python?

• Loops in Python are used to define variables.

• A loop in Python is a function that executes only once.

• A loop in Python is a type of data structure.

• A loop in Python is a construct that allows code to be executed repeatedly, using 'for' and 'while' statements.

What is the purpose of the 'for' loop in Python?

• To iterate over a sequence or iterable object.

• To handle exceptions in Python.

• To create a new variable in Python.

• To define a function in Python.

How do you define a function in Python?

• function_name{parameters}

• function_name(parameters) =>

• function_name: parameters

• def function_name(parameters):

What is the difference between a function and a method?

• A method can be called without an object, while a function requires an object.

• A function is independent, while a method is associated with an object.

• Functions and methods are the same and can be used interchangeably.

• A function is always part of a class, while a method can exist independently.
