[IOS] I made a widget that displays Qiita trends in Pythonista3. [Python]

Introduction

iPhone and iPad users, do you know an app called Pythonista3 that allows you to develop with Python on iOS devices? If you just want to run Python, I personally recommend Carnets --Jupyter. With Pythonista3, you can also develop functions that can be used from outside Abri, such as various shortcuts and widgets, and create games.

This time using such Pythonista 3 ** A widget that displays Qiita trends and opens the page in Safari when clicked ** I have created, so I would like to introduce it.

What i did

In the case of this widget, the contents of Launcher.py under ʻExample / Widget` can be used almost as it is, so based on that,

・ Ability to get trend titles and URLs from the top page of Qiita ・ A function to temporarily save the acquired information ・ A function to access Qiita again and update the information if a certain amount of time has passed since the previous acquisition of information

Added.

code

The number of columns, the number of rows in the folded state, and the font size variables are summarized after the import statement, so you can adjust the layout to your liking. It will be cramped and hard to push, but if you set the number of lines to 5 or more, you can display all daily trends (30).

			SHORTCUT = [{'lastUpdate':time.time() - 86400}]

				pickle.dump(SHORTCUT, f)
		SHORTCUTS = get_trend() if time.time() - SHORTCUT[-1]['lastUpdate'] > 1800 else SHORTCUT #1800 seconds from the last time(Half an hour)Update after the above

Summary

** Pythonista3 is good ** (I hope more packages can be used ...)
