Python Installation

Python installation involves downloading and installing the Python interpreter and associated tools on your computer. You can download Python from the official Python website and select the appropriate installer for your operating system. Once the installer is downloaded, you can run it to begin the installation process. The installer will guide you through the installation process and ask you to select the installation location and any additional components you want to install. After the installation is complete, you can run Python from the command line or an integrated development environment (IDE) to start writing and running Python code. To learn more -:

Python 2 Vs. Python 3

  • Syntax: Python 2 and Python 3 have slightly different syntax. Python 3 requires parentheses around the print statement, while Python 2 does not.
  • Unicode Support: Python 3 provides better support for Unicode, whereas Python 2 requires additional modules to support Unicode.
  • Print Function: In Python 2, the print statement is used to print output, while in Python 3, the print function is used.
  • Division: In Python 2, dividing two integers results in an integer, while in Python 3, dividing two integers results in a float.
  • Library Support: Python 3 has a larger and more active community, and many libraries are now available only for Python 3.
  • Backward Compatibility: Python 3 is not backward compatible with Python 2. This means that code written in Python 2 may need to be modified to work in Python 3. Refer here to learn more.

Variables in Python

In Python, variables are used to store data values. They are created when a value is assigned to them using the assignment operator "=" and can be of any data type. Python uses dynamic typing, which means that the type of a variable is determined at runtime based on the value assigned to it. Variables can be reassigned to new values at any time, and their values can be printed or used in operations within a Python program. Read here to know more

Data Types in Python

In Python, data types refer to the types of values that can be stored in variables. The common data types in Python include integer, float, boolean, string, list, tuple, and dictionary. Each data type has its own properties and methods, and Python automatically assigns the appropriate data type based on the value assigned to a variable. For example, if a variable is assigned a whole number value, it is automatically assigned an integer data type. Similarly, if a variable is assigned a value in quotes, it is assigned a string data type. Read here to know more

OOPs Concepts in Python

OOPs in Python is a programming paradigm based on the concept of objects. It provides the features of classes, objects, methods, and attributes. Encapsulation, inheritance, and polymorphism are some of the key features of OOP in Python that allow for more organized, reusable, and maintainable code. Encapsulation hides the implementation details of a class from other parts of the program, while inheritance and polymorphism help to reduce code duplication and make the code more flexible. OOP in Python is a powerful tool that can make programming easier and more efficient by promoting modularity, reusability, and maintainability of code.

Numbers in Python

Python provides three main types of numbers: integers, floating-point numbers, and complex numbers. Integers are whole numbers with no decimal points, while floating-point numbers include decimal points or scientific notation. Complex numbers consist of real and imaginary parts. Read here to know more

Python supports all basic arithmetic operations and includes many built-in mathematical functions in its math module. It also supports various number systems, such as binary, octal, and hexadecimal.

Python is a popular choice for scientific and numerical computing because of its powerful capabilities for handling large datasets, machine learning, and artificial intelligence.

User-Defined Functions

User-defined functions are created using the "def" keyword in Python, allowing for the creation of reusable code. Functions can accept input parameters, return values, or modify global variables. Properly designed functions improve code organization and readability, reduce code duplication, and simplify debugging. Python also supports passing functions as arguments to other functions and returning functions, enabling the creation of more flexible and reusable code.

Exception Handling

Exception handling in Python allows for handling runtime errors that may occur during program execution. The try-except block catches and handles exceptions that are created when an error occurs. Multiple except blocks can be used to handle different types of exceptions. The finally block executes regardless of whether an exception occurred or not and is typically used for cleanup tasks. The raise keyword allows for manually raising exceptions for indicating error conditions or triggering specific types of exceptions. Exception handling is crucial for writing reliable and error-free Python code, and it greatly enhances the overall usability and reliability of software applications. Read to know more
