不敢臭屁自己寫的有多完美，但是秉持著對 c 的嚴謹態度，至少能維持一定的水平的產出。
雖然 python 入手容易，但是看到那些“不謹慎的成品”，並且掛上 AI 高手的名號，真的心生恐懼！

當初有人挑戰我，上傳檔案不能用 "PUT"。
我就解釋給他說，當初 HTTP 剛流行時，上傳檔案，都是用 "PUT"。但不知何時，有的 HTTP Server 是用 "POST"，也有的 HTTP Server 是用 "GET"。
說完這些這些，那位人士說我在唬爛。不過我還是要再教育他，不管是用 "PUT"、"POST" 和 "GET"，都只是 HTTP Server 方有沒有嫁接後面的處理程序，至於對錯只能在 SPEC 上說。
因為你要對接的 HTTP Server不見得你能掌控。

希望在 ubuntu 有 Python editor 且能 debug，不要求有強大的功能。
eric 安裝方便，所以選擇此 IDE。
Eric is a full featured Python editor and IDE, written in Python. It is based on the cross platform Qt UI toolkit, integrating the highly flexible Scintilla editor control. It is designed to be usable as everdays' quick and dirty editor as well as being usable as a professional project management tool integrating many advanced features Python offers the professional coder. eric includes a plug-in system, which allows easy extension of the IDE functionality with plug-ins downloadable from the net.
Current stable version is eric7 based on PyQt6 (with Qt6) and Python 3.
$ sudo apt install -y ericCreated and designed by Lanka Hsu.
