Integers (int) in Python Integers (int) in Python are whole numbers without any decimal points. They can be positive, negative, or zero, and are represented as objects of variable size, meaning they can be as large as the memory of the computer allows. Characteristics of Integers Unlimited Size In Python, integers have unlimited size, which […]

Defining Specific Data Types In Python, you can define and work with specific data types beyond the built-in types. This includes creating custom data types using classes and utilizing more advanced data structures. Here, we’ll cover defining custom data types, using type hints, and working with complex data structures. Defining Custom Data Types Custom data

Defining Data Types In Python, although the language is dynamically typed, meaning you don’t need to explicitly declare the type of a variable, you can influence the data type of variables by initializing them with specific values or using type conversion functions. You can also use type annotations to document the expected types in functions

Obtaining the Data Type In Python, you often need to check or confirm the data type of a variable. This can be crucial for debugging, ensuring data consistency, or performing type-specific operations. Python provides several built-in functions to help you determine the data type of a variable. Using the type() Function The type() function is

Built-in Data Types Python provides several built-in data types that are essential for handling various kinds of data. These types are fundamental to programming in Python and include numeric types, sequence types, collection types, associative types, and special types. Numeric Types int (Integer) Description: Represents whole numbers without any decimal point. Can be positive, negative,

Introduction to Data Types What is a Data Type? Data types define the nature of values that variables can hold and the operations that can be performed on these values. In other words, a data type determines how Python interprets and manipulates values. Classification of Data Types In Python, data types can be classified into

Exercises Declaration and Display Exercise: Declare a variable x with the value 10 and display it. Solution: x = 10 print(x) Initialization and Type Exercise: Initialize a variable name with your first name and display its type. Solution: name = “John” print(type(name)) Arithmetic Operations Exercise: Declare two variables a and b with the values 5

The global Keyword Introduction In Python, the global keyword is used inside a function to indicate that a variable refers to a global variable rather than a local one. Without this keyword, any assignment to a variable inside a function creates a new local variable, and does not affect the global variable with the same

Course: Global Variables in Python Introduction In Python, variables can have different scopes, meaning the sections of code where they are accessible. A global variable is defined at the module level (i.e., outside of any function or class) and is accessible from any point in the module after its definition. However, functions and methods can
