Python… the most popular and favorite programming language in the world for programmers of all age groups. If you are a beginner this language is strongly recommended to learn first. Well, In programming, we all know the importance of code editor and IDEs to write our program and to execute it but choosing the best code editor or IDE is always a confusing question. Understand that the best code editor or IDE depends on so many things such as programming language, project type, project size, OS support and considering a lot of other features. If we talk about Python so this language is also not an exception.
We are going to discuss the code editor or IDEs for Python to use in 2020. This information is going to be based on the opinion given by experienced developers, public web data, some previous surveys like Python Developers Survey 2018 Results / Editors and IDEs and the most important person Guido van Rossum (Python Creator). Firstly understand that IDE and code editor both are different things.
- Text/Code Editor: Code editors are the lightweight tool that allows you to write and edit the code with some features such as syntax highlighting and code formatting. It provided fewer features than IDE.
- Integrated Development Environment (IDE): IDEs are full-fledged environment which provide all the essential tools needed for software development. It just doesn’t handle the code (for example, write, edit, syntax highlighting and auto-completion) but also provides other features such as debugging, execution, testing, and code formatting that helps programmers.
Let’s start with some overview of the best code editor based on certain terms…
What is Your Level?
- Beginner — IDLE (or Online Python Editors) is perfect choice for the first steps in python language. PyCharm is also good but takes the help of some experienced person while using this.
- Intermediate — PyCharm, Sublime, Atom, Vs Code.
- Advanced — PyCharm, Vim, Emacs, Sublime, Atom, Vs Code.
What’s Your End Goal?
- Web development — PyCharm Professional, VS Code
- Data Science — Spyder, Jupyter Notebook, PyCharm Professional
- Scripting — Sublime, Atom, PyCharm Community, Eclipse + PyDev
- QA — Sublime, Atom, PyCharm Community, Jupyter Notebook
What is Your Environment/OS?
- Linux, macOS — PyCharm, Sublime, Atom, Vim, Jupyter
- Windows — Sublime, VS Code, Eclipse + PyDev, PyCharm
- Multiple/mixed OS — PyCharm, Sublime, Atom
Which Hardware Do You Have?
- Bad — IDLE, Atom, Sublime, Online Editor
- Good — PyCharm, VS Code, Eclipse + PyDev
Note: We have considered limited terms but it also depends on budget, git integration, teamwork, previous programming knowledge.
