Raspberry Pi Code Editor All In One

We’ve chosen Python as the first programming language our Code Editor supports because it is popular in schools, CoderDojos, and Code Clubs.
Many educators and young people like Python because they see it as similar to the English language.

Python is also widely used by professional programmers and usually tops at least one of the industry-standard indexes that ranks programming languages.

We will be adding support for web development languages (HTML/CSS/JavaScript) to the Editor in the near future.

我们选择 Python 作为代码编辑器支持的第一种编程语言，因为它在学校、CoderDojos 和代码俱乐部中很流行。
许多教育工作者和年轻人喜欢 Python，因为他们认为它类似于英语。

Python 也被专业程序员广泛使用，并且通常至少在一项对编程语言进行排名的行业标准指数中名列前茅。

我们将在不久的将来向编辑器添加对 Web 开发语言 (HTML/CSS/JavaScript) 的支持。

beta

Code Editor is in beta
What does beta mean?
Beta means that we are not quite finished yet, and some things might not look or work as well as we’d like. However, it also means you are one of the first people to use our new Code Editor!

What next?
We'll soon be asking for your feedback, so we can work on making it better for you, and other digital makers.

`GPIO` module bug

ust the standard library and P5 for now

目前只有标准库和 P5

https://pypi.org/project/p5/

ImportError: No module named RPi on line 4 of main.py

# shell 获取时间戳 ✅
# SH_DATE=$(TZ=':Asia/Shanghai' date '+%Y-%m-%d %T');
# datetime = $(date '+%Y-%m-%d %T')

# Python 获取时间戳 ✅

# 转换为指定的格式

GPIO.cleanup()

print('结束闪烁 👌🏻')
