This page provides an overview of Pythonista’s user interface, and also contains some useful tips and tricks to help you get the most out of it.
Pythonista is divided into three panels: The script library, the code editor, and the interactive prompt, which also contains the documentation viewer. You can switch between these panels with left and right swipe gestures.
The Script Library#
The script library shows all the scripts you’ve written and those that are included
as examples. You can either view them as a list of file names, or as code snippet previews.
The view mode can be changed by tapping the
To create a new script, tap the
+ button at the bottom of the file browser.
This will open the template picker to select the type of file, and its name.
To delete scripts, or move them to a different folder, tap the Edit button or use drag’n’drop. Deleted scripts are moved to the special Trash folder, from where you can restore or delete them forever.
The script library also shows non-Python files, e.g. data files that your scripts create or work with. For many file types, a preview can be shown, and you can also open them in a different app on your device.
You can add your own file templates by creating files in the “File Templates” folder.
Files from other apps (or cloud providers) can be accessed from the “External Files” section. Pythonista supports editing files from other apps in-place, and you can also integrate entire folders (e.g. Git repositories) from other apps (e.g. Working Copy).
The script library supports drag’n’drop for moving files (requires iOS 12+).
You can add files and folders to the “Favorites” section for quick access from the side bar.
Swipe right on a file to open it in a new tab, or to mark it as a favorite for quick access.
If you have a hardware keyboard connnected, you can navigate the script library using arrow keys (return to select).
The Interactive Prompt#
The interactive prompt is the easiest way to get started with Python. Every time you enter a line of code, it is executed immediately, so you get quick feedback and can experiment with the syntax. Even if you know (almost) nothing about Python, you’ll be able to use the prompt as a powerful calculator.
You can get to the prompt at any time with a left swipe gesture. This area is also used for text output of any scripts that you run, and for keyboard input.
When you enter code, completions are suggested automatically.
consolemodule allows you to modify the console’s output font, colors, and to clear the text output programmatically.
Tap and hold the
^button to clear the console’s history.
Tap the console’s title to switch the interpreter (2.7 or 3.x) or to copy all text from the output.
(i)button in the top-righthand corner toggles the Object Inspector. It allows you to inspect variables and their attributes visually, by browsing the object hierarchy tree. The inspector can also preview certain types of images.
Tap and hold the “Clear” button to reset global variables, imported modules, etc.
The console can be shown in a compact form directly next to the editor by tapping the “split screen” button.
If you’ve used any programming editor before, you’ll probably feel right at home in Pythonista. For the most part, the editor behaves very similar to any other text area on iOS, but there are some additional features that might not be obvious at first.
First off, the keyboard contains additional keys with special characters that are useful for programming. These additional keys also work as a gesture area: You can slide across them with your finger to move the cursor, which makes it easier to position it precisely.
For navigating in complex scripts, you can tap the name of the script at the top of the screen, to get a popup of all functions, classes, and methods. You can also rename files from this popup.
One very powerful feature of the editor is that it is programmable itself.
You can use the
editor module for replacing text, positioning the
cursor, etc. You can then add your own scripts to the action (“wrench”) menu,
so that you can run them directly from the editor when working on your code.
Tap the Edit button in the editor actions menu to add your own scripts.
Have a look at the documentation about the
module for some interesting examples.
Tap with two fingers to select an entire line.
Color values (strings, e.g.
'#ff00ff') can be edited using a visual color picker. Simply put the cursor on the color value to show a color swatch, tap it to adjust the color.
(+)button in the bottom-righthand corner (while editing) to insert colors, image, font or sound effect names. This is mostly meant for use with the
PILmodules, but may also be helpful for web development.
Use the “Highlight All” menu item after selecting a word to quickly see all places where e.g. a variable name is used in your script.
The list of functions that appears when you tap the title of a script can be filtered by simply typing. If the keyboard is not yet visible when the list is shown, you can drag down to show the filter field.
If you have an external (e.g. Bluetooth) keyboard connected to your iOS device, you can navigate almost all of Pythonista using keyboard shortcuts.
Press and hold the Cmd (
⌘) key at any time to show a list of available shortcuts. Some shortcuts are only available in certain modes, e.g. while editing code or in the console.
In most lists, Pythonista supports navigation using the arrow keys, e.g. when you press Cmd+L to show the script’s outline, you can jump to a function using the up/down keys, confirming the selection with enter.
Common keyboard shortcuts (these work in all text areas on iOS):
Command + X – Cut
Command + C – Copy
Command + V – Paste
Command + Z – Undo
Command + Shift + Z – Redo
Command + A – Select All
Some of Pythonista’s keyboard shortcuts:
Command + R – Run
Command + L – Show outline (you can navigate in the outline using the up/down arrow keys and return)
Command + D – Insert snippet
Command + J – Show/hide console panel
Command + return – Focus on editor
Command + F – Toggle search
Command + G – Show next search result
Command + Shift + G – Show previous search result
Command + K – Clear console output
App Extensions and Shortcuts#
Pythonista contains various app extensions to integrate with other apps and parts of iOS.
You can use the sharing extension for running scripts in any app that uses the standard system share sheet. The custom keyboard extension allows you to run scripts in any app with text input. Pythonista URLs can be used to automate launching scripts from other apps (e.g. the Shortcuts app).
