Spyder is a free and open source scientific environment written in Python, for Python, and designed by and for scientists, engineers and data analysts. It features a unique combination of the advanced editing, analysis, debugging, and profiling functionality of a comprehensive development tool with the data exploration, interactive execution, deep inspection, and beautiful visualization capabilities of a scientific package. Spyder’s multi-language Editor integrates a number of powerful tools right out of the box for an easy to use, efficient editing experience. The Editor’s key features include syntax highlighting (pygments); real-time code and style analysis (pyflakes and pycodestyle); on-demand completion, calltips and go-to-definition features (rope and jedi); a function/class browser, horizontal and vertical splitting, and much more.

SASM (SimpleASM), simple Open Source crossplatform IDE for NASM, MASM, GAS, FASM assembly languages. SASM has syntax highlighting and debugger. The program works out of the box and is great for beginners to learn assembly language. SASM is translated into Russian, English, Turkish, Chinese, German, Italian, Polish, Hebrew, Spanish. In SASM you can easily develop and execute programs, written in NASM, MASM, GAS or FASM assembly languages. Enter code in form and simply run your program. In Windows SASM can execute programs in a separate window. Enter your input data in "Input" docking field. In "Output" field you can see the result of the execution of the program. Wherein all messages and compilation errors will be shown in the form on the bottom. You can save source or already compiled (exe) code of your program to file and load your programs from file.

Code faster with the IDE for today’s web languages – Python, PHP, Perl, Golang, Ruby, and more. Powerful editor with syntax highlighting, autocomplete, code refactoring, and more. Visual debugger and more to debug, inspect, and test your code. Support for Git, Mercurial, Subversion, CVS, Perforce and Bazaar. Tons of add-ons for customizing and extending features. Great tools for pair programming and collaboration. Python, PHP, Perl, Go, Ruby, Node.js, JavaScript, and more. Define your own workflow with easy file and project navigation. Backed by ActiveState, trusted by developers and enterprises.

Leo is an outlining-oriented project manager and browser. With Leo you can organize programs, web sites, URL's, pictures or any other kind of data. Leo is fully scriptable in Python. Leo is 100% pure Python. It requires the Qt gui toolkit.

Positron is a next-generation integrated development environment (IDE) created by Posit PBC (formerly RStudio Inc) specifically tailored for data science workflows in Python, R, and multi-language ecosystems. It aims to unify exploratory data analysis, production code, and data-app authoring in a single environment so that data scientists move from “question → insight → application” without switching tools. Built on the open-source Code-OSS foundation, Positron provides a familiar coding experience along with specialized panes and tooling for variable inspection, data-frame viewing, plotting previews, and interactive consoles designed for analytical work. The IDE supports notebook and script workflows, integration of data-app frameworks (such as Shiny, Streamlit, Dash), database and cloud connections, and built-in AI-assisted capabilities to help write code, explore data, and build models.

Data validation and settings management using Python type hinting. Fast and extensible, pydantic plays nicely with your linters/IDE/brain. Define how data should be in pure, canonical Python 3.6+; validate it with pydantic. id is of type int; the annotation-only declaration tells pydantic that this field is required. Strings, bytes or floats will be coerced to ints if possible; otherwise an exception will be raised. name is inferred as a string from the provided default; because it has a default, it is not required. signup_ts is a datetime field which is not required (and takes the value None if it's not supplied). pydantic will process either a unix timestamp int (e.g. 1496498400) or a string representing the date & time. friends uses python's typing system, and requires a list of integers. As with id, integer-like objects will be converted to integers.

A collection of extensions for Python's IDLE, the Python IDE built with the tkinter GUI toolkit.

DrPython is a highly customizable cross-platform ide to aid programming in Python. It was developed with teaching in mind, and has a clean, simple interface. It is written in Python, using wxPython as the gui.
