Python for Beginners | Top 10 Python Libraries and Packages You Must Know in 2023
Hello, and welcome to this post on the top 10 Python libraries and packages that you must know in 2023.
What is Python?
Python is a powerful programming language used extensively in various domains, including data science, machine learning, web development, and more. One of the major reasons for Python's popularity is its vast collection of libraries and packages that simplify complex tasks. So, let's explore the top 10 Python libraries and packages you need to know in 2023.
What is a Python library?
A Python library is a collection of pre-written code that can be used to perform a specific set of tasks. Python libraries are designed to simplify complex tasks by providing pre-written code that can be imported and used in your programs. Python libraries can be used for a wide range of tasks such as numerical computing, data analysis, machine learning, web development, and more.
How do Python libraries work?
Python libraries work by providing pre-written code that can be imported into your Python program. When you import a Python library, you can use the functions and classes provided by the library to perform specific tasks. Python libraries can be installed using a package manager such as pip, which is a tool for installing and managing Python packages.
How to use a Python library?
To use a Python library, you first need to install it using a package manager such as pip. Once you have installed the library, you can import it into your Python program using the import statement. Here's an example:
In this example, we have imported the NumPy library and used it to create a NumPy array. We then printed the array using the print() function.
Python libraries often come with documentation that explains how to use the library, including examples and tutorials. You can also find many resources online that provide information about Python libraries and how to use them.
