Introduction to Python for Machine Learning
In the 21st century, most of the applications developed by companies are somehow built using Artificial Intelligence, Machine Learning, or Deep Learning that uses Python Machine Learning library. Usually, AI projects are distinct from conventional projects in the software industry. Variations in development approaches lie in the application framework, the necessary skills needed for the AI-based application, and the need for in-depth analysis.
Hence, one of the important factors involved in developing AI-based applications is the use of a suitable programming language. We should employ a programming language that is efficient in making the applications stable and extensible. For this, companies use the Python programming language as it offers a lot of libraries and packages for the development task, and hence, it is widely used for working on AI-based projects.
Benefits of Using Python
Here are a few of the benefits of using Python:
- Simple and compatible: Python provides descriptive and interactive code. Although complicated algorithms and adaptable workflows are behind Artificial Intelligence and Machine Learning, the simplicity of the Python Machine Learning library and framework enables application developers to develop reliable systems.
- Platform-independent: One aspect adding to the success of Python is that it is a language that is independent of the platform on which it is being operated. There are various platforms that support Python, such as Windows, macOS, and Linux. For the most commonly used software, Python language code can be used to build discrete executable programs. This ensures that Python programs can be quickly deployed, and we can use them without having a Python interpreter on operating systems.
- Large community: According to a survey by Stack Overflow, it is one of the top 10 programming languages used by various software industries. Also, Python is one of the most searched programming languages than any other. It is considered the best language for Web Development as well. It has a large community of developers that can help the newbies starting with Python programming to learn and grow with experienced developers.
Now, as we have discussed Python and its benefits, let’s look at the top 10 Python libraries for Machine Learning.

Python Libraries List
The following is the list of some of the most commonly used Python libraries:
Pandas library in Python
One of the widely used Python’s Machine Learning libraries is Pandas. Pandas is the best Python library that is majorly used for data manipulation. It uses handy and descriptive data structures such as DataFrames to create programs for implementing functions. Developed on top of NumPy, it is a quick and easier-to-use library.
Pandas provide data reading and writing capabilities using various sources such as Excel, HDFS, and many more. If you are planning on a use case for a real-world Machine Learning model, then, sooner or later, you would use Pandas for implementing it. Below are the advantages and disadvantages of using Pandas.
- It has descriptive, quick, and compliant data structures.
- It supports operations such as grouping, integrating, iterating, re-indexing, and representing data.
- The Pandas library is very flexible for usage in association with other libraries.
- It contains inherent data manipulation functionalities that can be implemented using minimal commands.
- It can be implemented in a large variety of areas, especially related to business and education, due to its optimized performance.
- It is based on Matplotlib, which means that an inexperienced programmer needs to be acquainted with both libraries to understand which one will be better to solve a specific business problem.
- Pandas is much less suitable for quantitative modeling and n-dimensional arrays. In such scenarios, where we need to work on quantitative/statistical modeling, we can use Numpy or SciPy.
Further, we will look around Matplotlib, which is another Python ML library.
Matplotlib library in Python
Matplotlib is a library used for data visualization. It is a sub-part of SciPy. It deals with NumPy structures and high-level models such as Pandas. It is considered as one of the essential libraries for machine learning in python for performing data visualization.

- Matplotlib has a strong dependency on NumPy and other such libraries for the SciPy stack.
- It has a high learning curve as the use of Matplotlib takes quite a lot of knowledge and application from the learners’ end.
- There can be confusion for developers because Matplotlib provides two distinct frameworks: Object-oriented and MATLAB.
- Matplotlib is a library used for data visualization. It is not suitable for data analysis. To get both data visualization and analysis, we will have to integrate it with other libraries.

- NumPy is highly dependent on non-Pythonic entities. It uses the functionalities of Cython and other libraries that use C/C++.
- Its high productivity comes at a price.
- The data types are hardware-native and not Python-native, so it costs heavily when we want to translate NumPy entities back to Python-equivalent entities and vice versa.
