In how many different ways can you work in Python?
There are multiple ways to work in Python: Interactive mode: Allows executing Python statements and expressions one at a time, interactively, in a command-line environment like Python’s interactive shell or an Integrated Development Environment (IDE) with a Python console. Script mode: In this mode, Python code is written in a script file (with a .py…

What are the advantages disadvantages of working in interactive mode in Python?
Advantages/Disadvantages of working in interactive mode in Python: Advantages: Quick feedback: Interactive mode allows you to immediately see the results of each statement or expression, which can be helpful for testing small pieces of code or experimenting. Exploratory programming: It allows you to interactively explore libraries, test functions, and experiment with code snippets. Learning and…

What are operators? Give examples of some unary and binary operators.
Operators: Operators are symbols or keywords in a programming language that perform operations on operands (values or variables). They are used to manipulate data and perform calculations in expressions. Examples of unary operators: Unary minus/negation: – (e.g., -x) Unary plus: + (e.g., +x) Increment: ++ (e.g., x++) [Note: Python does not have a built-in increment…

What is an expression and a statement in Python?
Expression and Statement: Expression: An expression is a combination of values, variables, operators, and function calls that evaluates to a single value. It can be as simple as a variable or a complex combination of multiple operators and operands. Examples of expressions: 5 + 3 (evaluates to 8) x * 2 (evaluates to the value…

What all components can a Python program contain?
Components of a Python program: A Python program can contain the following components: Import statements: These are used to import external modules or libraries for additional functionality. Variable declarations: Variables are created to store and manipulate data. Function definitions: Functions are blocks of reusable code that perform specific tasks. Conditional statements: These statements control the…

What are variables? How are they important for a program?
Variables: Variables are named containers used to store and manipulate data in a program. They act as placeholders that hold values, which can be of different types such as numbers, strings, or objects. Variables have names assigned to them, allowing developers to refer to and modify the stored data throughout the program. Variables are important…

What are the various ways of creating a list?
There are several ways to create a list in Python: Using square brackets: [ ] Example: my_list = [1, 2, 3, 4] Using the list() constructor: Example: my_list = list([1, 2, 3, 4]) Using list comprehension: Example: my_list = [x for x in range(1, 5)] Creating an empty list and adding elements using the append()…

Write a program to calculate the mean of a given list of numbers.
def calculate_mean(numbers): total = sum(numbers) mean = total / len(numbers) return mean my_list = [1, 2, 3, 4, 5] mean_value = calculate_mean(my_list) print(“Mean:”, mean_value)

Why are lists called a mutable data type?
Lists are called mutable data types because they can be modified after they are created. This means that elements within a list can be changed, added, or removed. You can modify the value of an existing element by assigning a new value to its index, append new elements to the end of the list, insert…
