21 Essential Python Tools
Become familiar with Python's essential tools for software development, data analysis, and visualization.
Python programming language is one of the most popular programming languages. This is a simple, powerful, open-source project driven by an active community. Python is popular for its many uses; it can be used to build software, create web services, analyze data, and train machine learning models for free.
This post includes a list of Python tools beginners can use to start Python development. Additionally, it will help Python developers and data professionals become more productive. These tools can help you make the most of Python, no matter where you are in your Python journey.
Development Tools for Python
Python solutions are built faster and more reliably with development tools. The python package manager, Integrated Development Environment (IDE), and productive extensions are included. With these tools, testing, debugging, and deploying solutions have been made easier.
Juypter Notebook
You can experiment with code using Jupyter Notebook, a web-based IDE. There is a fair amount of interest in it among data scientists and machine learning practitioners. Instead of running the whole file, they can run and test a small set of code and view the results.
Markdown can be used to add a description and heading, and PDF and .ipynb files can be exported.
Jupyter Notebooks are created by mixing scientific computation with Python development. Data scientists today use it to create reports, data analysts use it to teach data science classes, and machine learning engineers use it to build high-performing models.
There are production-ready solutions being built on it, and cloud computing giants like Amazon are integrating it into their ecosystems as well.
Pip
To install and manage Python software, Pip uses the Python Package Index. 393,343 projects are available for you to download and install. Python’s ecosystem relies on it.
pip install <package_name>Unlike other installers, Pip does more than install software. Python environments can be created and managed, dependencies installed, and packages can be installed from third-party repositories using URLs.
python -m pip install -r requirements.txtVS Code
With Visual Studio Code, you have access to a powerful code editor that’s free, lightweight, and easy to use. All types of applications can be built, tested, deployed, and maintained without leaving the software window. Syntax highlighting, code auto-completion, language, Git, and in-line debugging are all included. Cloud deployments and pre-build systems can be accomplished with extensions.
In addition to its popularity as the world’s most popular IDE, VSCode offers a number of free extensions for improved user experience. Data scientists can run experiments on Jupyter notebooks, edit markdown files, integrate SQL server, collaborate on projects, autocomplete code, and access in-line code help with the extensions. Use extensions and run everything from VSCode software, such as a bash terminal and a browser, instead of using multiple software programs.
Python Web Scrapping
By scraping websites, data scientists and analysts can collect data from them. The hardest part of web scraping is cleaning data and converting it into a readable format. Web scraping and data cleaning tools will be discussed in this section.
Request
You can send HTTP requests easily with Requests. You can use the get JSON method of the requests API instead of manually adding authentication, arguments, and configuration query strings to your URLs. Scraping multiple-page websites with Requests is quite popular among data professionals.
Beautiful Soup
HTML and XLM data are cleaned and extracted using Beautiful Soup. By parsing HTML text, this tool allows data scientists to create structured tables or pandas dataframes from text data.
You can extract complex HTML data with just a few lines of code. Some data can be accessed with only a table tag, and you don’t need to parse the text.
Scrapy
In the world of web scraping and web crawling, Scrapy is an open-source and collaborative framework. With it, data can be extracted in a structured format from websites of multiple pages in a fast, simple, and extendable manner. Automated testing, data mining, and monitoring are among its uses.
Flask
With Flask, you can build a simple web API with just a few lines of code, much easier than with Django’s framework.
WSGI (Web Server Gateway Interface) and Jinja2 are the core components of Flask. In addition to blogging websites, social media apps, portfolio websites, machine learning applications, and analytics dashboards, it can be used to create simple and large-scale web applications.
Streamlit
Building and sharing web applications is easy with Streamlit. Data science portfolios, analytics dashboards, machine learning web applications, educational tutorials, and geospatial and computer vision applications can all be created within minutes. Like declaring variables in Python, you just need to add a widget. Defining routes, handling HTTP requests, HTML, CSS, and JavaScript are not required.
In the world of web development, it is the gateway for data scientists and analysts. For this reason, most data scientists use Streamlit to demonstrate financial reports, research, and machine learning concepts.
FastAPI
Using FastAPI, you can create high-performance web APIs. The process for building production-ready web applications is similar to Streamlit. Using the GUI interface or HTTP requests, you can access the web app after it has been deployed.
There is no waiting time, it is easy to use, and it is robust. Machine learning models are easy to deploy. Web application authentication and crisis management are also handled by it.
Pandas
Pandas is an entry point into the world of data science. In the beginning, you will learn how to read a CSV file using read_csv(). All data professionals should have access to Pandas.
Data can be loaded, cleaned, manipulated, analyzed, visualized, and saved into various file formats. It is easy to use the pandas API. CSV files, text files, Microsoft Excel, SQL databases, and HDF5 files can all be loaded and saved.
NumPy
Most modern tools are built upon NumPy, one of the most fundamental Python packages for scientific computations. The Numpy array is used by data scientists to perform mathematical calculations and manipulate data. In addition to performing logical, shape manipulation, sorting, selection, basic statics operations, and random simulations, it also provides multidimensional array objects.
You can learn how to convert complex equations into Python code with Numpy, a Python library that allows you to learn the fundamentals of mathematics in data science. In addition to creating machine learning models, it allows you to create customized statical formulas, perform scientific simulations and perform advanced data analytics.
SQLAlchemy
You can access and manage relational databases with SQLAlchemy, a Python SQL toolkit. The powerful features of SQL can be achieved using Object Relational Mapper.
Data scientists and analysts who process and analyze data in Python need this tool. In order to perform similar tasks in an effective manner, you can either use SQL scripts or an intuitive Python API.
Dask
In order to process big data or files, Dask is an essential tool. NumPy, pandas, and scikit-learn use parallel computing to perform similar tasks.
It will take at least 10 minutes to run a simple logical function on a large dataset of 4GB. Even with better machines, processing times cannot be improved. Using parallel data collection and dynamic task scheduling, Dask achieves fast results.
There are similarities between the APIs of pandas and scikit-learn. In addition to being flexible, native to Python, and scalable up to 1000 cores, it provides humans with rapid feedback and diagnostics to assist them in their work.
Matplotlib
Matplotlib is an excellent tool for visualizing data. It is covered in many introductions to data visualization.
A fully customizable static, animated, and interactive visualization can be created with Matplotlib. A 3D, multilevel, and detailed visualization can be plotted using this intuitive tool. In the gallery, you can find hundreds of examples of different visualizations.
Seaborn
For creating attractive statistical graphics, Seaborn uses Matplotlib’s high-level interface. In a similar way to Matplotlib, you can create interactive visualizations by typing a single line of code.
When you are new to data visualization, it works wonders because it is highly adaptable. Matplotlib allows you to customize graphs by adding new axes, editing titles, or even changing colors. Depending on your needs, seaborn may calculate everything for you and display the distplot, violin plot, residual plot, implot, joint plot, and boxplot for you.
