Data Types Strings, integers, and floating-point numbers are just a few of the built-in data types available in Python. In Python, the type of value a variable holds is referred to as a data type.

There are a few pre-built data types in Python:

Numbers: This includes floating-point numbers like 3.14 and 1.23, as well as integers like 1, 2, and 3. A sequence of characters, such as "hello" and "world," is called a string. Single or double quotes can be used to enclose strings. Lists: A collection of items that can be arranged in any order. Items are separated by commas in lists, and square brackets are used to write them. Tuples: Similar to a list, a tuple cannot be changed because its items cannot be changed. Round brackets are used to write plurals, and commas are used to separate items. Dictionary: Key-value pairs are the foundation of a dictionary. Curly braces are used to write dictionaries, and colons are used to separate values and keys in Boolean: True or False, there is no such thing as a Boolean data type: The null value or none is represented by the special constant None. The built-in type() function can be used to determine a variable's data type.

Operators Python provides support for a variety of logical and mathematical operators, including +, -, *, /, and %. Operators are special symbols in Python that carry out particular operations on one or more operands (the values or variables being operated on).

It is used to execute various codes based on particular conditions with conditional statements. The if-else statement is the most prevalent type of conditional statement. The following is the basic syntax for an if-else statement:

condition if:

The code that will be executed if the condition is met; otherwise:

code to be executed if the condition is false In the if statement, the word "condition" refers to a Boolean expression that can be True or False. The code in the if block will be executed if the condition is true; otherwise, the code in the else block will be executed.

There are two types of loops in Python: while loops and for loops You can run a block of code repeatedly with these. A block of code can be repeatedly executed using loops in Python. Loops come in one of two varieties: while loops and for loops

Functions A function is a block of Python code that can be used again and again in your program. Functions are useful for dividing a complicated program into smaller, easier-to-manage pieces.

A function's basic syntax is as follows:

def parameter_name of function:

the code that will be executed Here, the function's name is function_name, and the input values that are supplied to the function are referred to as "parameters." When the function is called, the code inside it is executed.

Libraries A library is a collection of code that has already been written and can be used for a variety of tasks. Without having to write your own code, you can add functionality to your program using libraries.

There are numerous Python libraries available; some of the most well-known include:

NumPy: a Python library for manipulating numerical data. It gives you tools for working with mathematical functions, matrices, and arrays. Pandas: a Python library for working with data. It offers tools for manipulating, analyzing, and displaying data. Matplotlib: a Python library for making visualizations. It gives you tools to make graphs, plots, and other kinds of graphics. Scikit-learn: a Python library for machine learning. It has tools for regression, classification, clustering, and more. TensorFlow: a Python library for the creation and training of machine learning models. Deep learning, computer vision, natural language processing, and other applications make extensive use of it. OpenCV: a Python library for computer vision. It has tools for feature extraction and detection, image and video processing, and more. In Python, you must first install a library before you can import it into your program and begin using its classes and functions. Pip, Python's package installer, can be used to install a library. The library can be imported and utilized immediately after installation. (Python Classes in Ahmednagar)

Classes and Objects In Python, an object is an instance of a class and a class is a blueprint for creating objects. Classes are a means of modeling real-world concepts and combining data and behavior. Classes and objects are used to represent real-world concepts in object-oriented programming (OOP), a programming paradigm that organizes code in a way that is simple to understand, maintain, and extend.

Here are some basic concepts in Python for beginners – A variable is a container for storing a value in Python. By assigning a value to a variable with the "=" operator, you can create a variable. Any data type, including strings, integers, and floating-point numbers, can be used to represent the value. A variable can be used throughout your program once it has a value.
