• 最關鍵的 Python 代碼指標

  • STEVE DOWER

「Code metrics are a popular way to analyse the complexity of our software. For some reason, we are attracted to single-figure summaries of quality, whether it’s lines of code, cyclomatic complexity, or the Pylint score. Personally, I think using these are about as valuable as judging another person based on one of their visible or measurable characteristics.」

#7 Scikit-learn
#6 Seaborn
#5 NumPy
#4 Keras
#3 SciPy

文科生的戰鬥, 雖然沒辦法象 wuhan2020 們那樣快速組織工程師,
先於國家完成各類實用系統;

可是, 文科生經過大量海外報道的瀏覽/對比/翻譯/報道/...

能夠幫助人們經過真實世界的反應, 來更好的理解當前狀態.

並且, 一個徹底沒有技術基礎的文科團隊, 天然經過 github 完成全部協同,
實在..感動 -> github 太好用了.
