Pyzo is a small, open source, cross-platform, Python IDE focused on interactivity and introspection. It’s a good environment for developers focused on scientific computing. Its practical design is aimed at simplicity and efficiency.
Pyzo consists of two main components, the editor and the shell, and uses a set of pluggable tools to help the programmer in various ways. Some example tools are source structure, project manager, interactive help, and a workspace.
The software is written in (pure) Python 3 and uses the Qt GUI toolkit. Binaries are provided for all major operating system which makes it quick to get started.
Pyzo uses code and concepts that are inspired by IPython, Pype, and Spyder.
Key Features
- Introspection information is queried from the active shell, and from the source code (by continuously parsing the file in a separate thread).
- Auto completion for any object in the active Python session and all __builtins__.
- Optional auto completion for Python keywords.
- Auto completion for functions, classes, and class attributes defined in the current file in the editor (taking inheritance into account, even if a super class is defined in the shell).
- Shows signature of functions (from the shell or from the source) using a call-tip.
- Interactive help for all objects in the active Python session by moving up/down the auto completion list, by double-clicking on a name, or by filling in the name directly.
- Interactive help show the docstrings of properties (rather than of the returned object).
- Allows various ways to interactively run code.
- Using an intuitive shortcut editor, a shortcut can be created for any item in the menu.
- Choose between different Qt themes.
- Full Unicode support in both editor and shell.
- Editor:
- Supports auto indentation.
- Automatically determines the indentation width when loading a file.
- Matlab-style cell system to mark code sections (by starting a line with ‘##’).
- Syntax highlighting for Python, Cython, C, and more to come.
- Supports commenting and uncommenting selected lines.
- Drag-‘n-drop files or directories to open them.
- Find/Replace (also supports regular expressions).
- The line ending style can be changed.
- Optionally use tabs, or insert tabs as spaces.
- Indentation guides.
- View whitespace / line endings.
- Zooming.
- Undo / redo.
- Highlighting of current line.
- Long line indicator.
- Choice of multiple fonts, Pyzo comes with two attractive fonts.
- Breakpoints for debugging.
- Various handy tools included, plus the ability to make your own.
- File browser – list all files in your projects by bookmarking the directories of your projects. Easy switching between projects.
- History viewer.
- Interactive help – displays help information interactively (on selection and scrolling through an autocompletion list).
- Logger – a logger shell that displays Pyzo’s log messages and can be used for development or for changing advanced settings.
- Source structure – lists the structure of the source in a tree widget. It can list classes, functions (and methods), import statements, cells, and todo items.
- Web browser.
- Workspace – lists all variables (also in debug mode).
- Export to PDF.
- Syntax parsing: Python, Python 2, Python 3, Plain, C, sexpr, cpython, and wat.
