Aug 1, 2024 · Scikit-learn: It is a famous Python library to work with complex data. Scikit-learn is an open-source library that supports machine learning. It supports variously supervised and unsupervised algorithms like linear regression, classification, clustering, etc. This library works in association with Numpy and SciPy.
An example of both a module and a package is a directory full of other modules and subdirectories. It isn’t easy to distinguish between a box and a library in Python. Using a Python library is convenient to include reused code into your projects and programs. Libraries in Python are much more general than those in languages like C++ or C.
- NumPy. NumPy is one of the most widely-used Python libraries. It contains functionality for fast and efficient numerical computations, but its strength lies in working with arrays.
- pandas. The pandas library has become the backbone of data analysis in Python; it’s a must-know for those of you wanting to learn how to work with data.
- matplotlib. Producing nice visualizations quickly and easily is a key skill for many Python projects. Although there are many libraries for producing different kinds of plots in Python, matplotlib should be your first stop.
- os. This one isn’t as glamorous as some of the other Python libraries on this list. However, it comes in handy when you need to interact with the operating system from within your Python program.
A module may contain variables, functions, classes etc. Let's see an example, Let us create a module. Type the following and save it as example.py. # Python Module addition def add(a, b): result = a + b. return result. Here, we have defined a function add() inside a module named example.

May 3, 2024 · This statement allows you to use the defined functions, classes, and variables from the external library in your program. The syntax for importing a library is: import library_name. Here, library_name is the name of the library you want to import. Once you import the library, you can access its functions and classes using the dot notation.

Mar 5, 2024 · A library in Python contains modules that include functions, methods, and types that help you to perform many actions without writing your own code. For example, if you need to handle dates and times in your program, you can use the datetime library in Python which has all the functions related to date and time. To use a library, you typically ...
