RPA for Python 🐍

v1.45 | Use Cases | API Reference | About & Credits | Run on Cloud | PyCon Video | Telegram Chat

This tool was previously known as TagUI for Python. More details on the name change, which is backward compatible so existing scripts written with import tagui as t and t.function() will still work.

RPA for Python demo in Jupyter notebook

To install this Python package for RPA (robotic process automation) -

pip install rpa

To use it in Jupyter notebook, Python script or interactive shell -

import rpa as r

Notes on different operating systems and optional visual automation mode -

  • 🏳️‍🌈 Windows - if visual automation is cranky, try setting your display zoom level to recommended % or 100%
  • 🍎 macOS - Catalina update introduces tighter app security, see solutions for PhantomJS and Java popups
  • 🐧 Linux - visual automation mode requires special setup on Linux, see how to install OpenCV and Tesseract

Use Cases

RPA for Python's simple and powerful API makes robotic process automation fun! You can use it to quickly automate away repetitive time-consuming tasks on websites, desktop applications, or the command line.

WEB AUTOMATION 🕸️

r.init()
r.url('https://www.google.com')
r.type('//*[@name="q"]', 'decentralization[enter]')
print(r.read('result-stats'))
r.snap('page', 'results.png')
r.close()

VISUAL AUTOMATION 🙈

r.init(visual_automation = True)
r.dclick('outlook_icon.png')
r.click('new_mail.png')
...
r.type('message_box.png', 'message')
r.click('send_button.png')
r.close()

OCR AUTOMATION 🧿

r.init(visual_automation = True, chrome_browser = False)
print(r.read('pdf_window.png'))
print(r.read('image_preview.png'))
r.hover('anchor_element.png')
print(r.read(r.mouse_x(), r.mouse_y(), r.mouse_x() + 400, r.mouse_y() + 200))
r.close()

KEYBOARD AUTOMATION 🎹

r.init(visual_automation = True, chrome_browser = False)
r.keyboard('[cmd][space]')
r.keyboard('safari[enter]')
r.keyboard('[cmd]t')
r.keyboard('mortal kombat[enter]')
r.wait(2.5)
r.snap('page.png', 'results.png')
r.close()

MOUSE AUTOMATION 🐭

r.init(visual_automation = True)
r.type(600, 300, 'open source')
r.click(900, 300)
r.snap('page.png', 'results.png')
r.hover('button_to_drag.png')
r.mouse('down')
r.hover(r.mouse_x() + 300, r.mouse_y())
r.mouse('up')
r.close()

TELEGRAM NOTIFICATION ☎️

r.telegram('1234567890', 'ID can be string or number, r.init() is not required')
r.telegram(1234567890, 'Hello World. Olá Mundo. नमस्ते दुनिया. 안녕하세요 세계. 世界,你好。')
r.telegram(1234567890, 'Use backslash n for new line\nThis is line 2 of the message')
r.telegram(1234567890, 'Sent using my VPS server endpoint https://tebel.org/rpapybot')
r.telegram(1234567890, 'Sent using your own hosted endpoint', 'https://your_endpoint')

GENERAL NOTES

See sample Python script, the RPA Challenge solution, and RedMart groceries example. To send a Telegram app notification, simply look up @rpapybot to allow receiving messages. To automate Chrome browser invisibly, use headless mode. To run 10X faster instead of normal human speed, use turbo mode (read the caveats!).

You can even run on your phone browser using this Colab notebook (eg datascraping with up to 5 Colab sessions). By design this package has enterprise security and you can install, update and use it without the internet. You can fully control error handling if you wish to, eg snapshot of missing element or posting to custom API endpoint.

For fine-grained control on web browser file download location, use download_location(). For overriding parent folder location to install and invoke TagUI (forked version optimised for this package), use tagui_location().

ELEMENT IDENTIFIERS

An element identifier helps to tell RPA for Python exactly which element on the user interface you want to interact with. For example, //*[@id='email'] is an XPath pointing to the webpage element having the id attribute 'email'.

  • 🌐 For web automation, the web element identifier can be XPath selector, CSS selector, or the following attributes - id, name, class, title, aria-label, text(), href, in decreasing order of priority. Recommend writing XPath manually or simply using attributes. There is automatic waiting for an element to appear before timeout happens, and error is returned that the element cannot be found. To change the default timeout of 10 seconds, use timeout() function. PS - if you are going to use a Chrome extension for XPaths, use SelectorsHub.

  • 📸 An element identifier can also be a .png or .bmp image snapshot representing the UI element (can be on desktop applications, terminal window or web browser). If the image file specified does not exist, OCR will be used to search for that text on the screen to act on the UI element containing the text, eg r.click('Submit Form.png'). Transparency (0% opacity) is supported in .png images. x, y coordinates of elements on the screen can be used as well. Notes for visually automating 2 monitors, macOS Retina display issue and solution.

  • 📄 A further image identifier example is a png image of a window (PDF viewer, MS Word, textbox etc) with the center content of the image set as transparent. This allows using read() and snap() to perform OCR and save snapshots of application windows, containers, frames, textboxes with varying content. See this image example of a PDF frame with content removed to be transparent. For read() and snap(), x1, y1, x2, y2 coordinates pair can be used to define the region of interest on the screen to perform OCR or capture snapshot.

CORE FUNCTIONS

Function Parameters Purpose
init() visual_automation = False, chrome_browser = True start TagUI, auto-setup on first run
close() close TagUI, Chrome browser, SikuliX
pack() for deploying package without internet
update() for updating package without internet
debug() True or False print & log debug info to rpa_python.log

by default RPA for Python runs at normal human speed, to run 10X faster use init(turbo_mode = True)

About & Credits

TagUI is a leading open-source RPA software 🤖 with tens of thousands of users. It was created in 2016-2017 when I left DBS Bank as a test automation engineer, to embark on a one-year sabbatical to Eastern Europe. Most of its code base was written in Novi Sad Serbia. My wife and I also spent a couple of months in Budapest Hungary, as well as Chiang Mai Thailand for visa runs. In 2018, I joined AI Singapore to continue development of TagUI.

Over a few months in 2019, I took on a daddy role full-time, taking care of my newborn baby girl and wife 🤠🤱. In between nannying, I used my time pockets to create this Python package built on TagUI. I hope that RPA for Python and ML frameworks would be good friends, and pip install rpa would make life easier for Python users. I am maintaining the package in my personal time and I'm happy that tens of thousands of people use it now.

At only ~1k lines of code, it would make my day to see developers of other languages port this project over to their favourite programming language. See ample comments in this single-file package, and its intuitive architecture. Work is now under way by other open-source folks to create TagUI packages for C# .NET and Go languages.
