Python Basic Syntax and Data Types: A Comprehensive Overview

Basic Syntax and Data Types:

Variables and Data Types (int, float, str, bool, etc.)

• What are variables in Python? Rules for naming variables in Python.

Explain how Python variables are declared and assigned values.

Describe the naming conventions and restrictions for variable names.

• What are the built-in data types in Python?

Python provides several built-in data types to represent different kinds of data.

• Differentiate between mutable and immutable data types in Python.

Give examples of mutable and immutable data types.

• What is dynamic typing in Python?

Explain how Python handles variable types dynamically at runtime.

• How do you convert one data type to another in Python?

Demonstrate explicit type conversions (casting) and implicit type conversions.

• Explain the difference between the int and float data types.

Describe how Python handles integers and floating-point numbers, including precision and operations.

• What is the maximum and minimum value for an int, float, and string data type in Python?

Explain the limits of data types on different platforms.

• How do you create a string in Python?

Create strings using single quotes, double quotes, and triple quotes.

• How do escape characters work in Python strings? Provide some examples.

Describe how escape characters are used to include special characters in strings.

• How do you concatenate strings in Python?

Show various methods for combining strings.

• How does Python handle string interpolation?

Describe string interpolation and how to achieve it using f-strings or the .format() method.

• What is the best way to check whether a string contains a specific substring in Python?

Check for substrings in a string using different approaches.

• What are Boolean values used for in Python?

Describe the significance of Boolean values (True and False) in control flow.

• How to convert a string containing a numerical value to an actual number?

Illustrate the process of converting a string to an int or float data type.

• How do you handle user input in Python, and what data type is the input?

Demonstrate how to obtain user input and how Python interprets it by default.

• What is the NoneType data type, and what does it represent?

Explain the purpose of the NoneType data type and its significance in Python.

• What is the difference between == and is in Python?

Clarify the distinction between equality (==) and identity (is) comparisons.

• How do you check the type of a variable in Python?

Provide methods to determine the data type of a variable during runtime.
