numpy 和 Pandas 似乎超級火紅的，好多python 的實體書都有安插詳細的教學，似乎應該找時間學一下。
對 Pandas 覺得不太熟練？最好的方式就是找練習題來複習課程中所學到的觀念，參考看看這個 github 開源專案:

Pandas Exercises
Fed up with a ton of tutorials but no easy way to find exercises I decided to create a repo just with exercises to practice pandas. Don’t get me wrong, tutorials are great resources, but to learn is to do. So unless you practice you won’t learn.
There will be three different types of files:
1. Exercise instructions
2. Solutions without code
3. Solutions with code and comments
My suggestion is that you learn a topic in a tutorial or video and then do exercises. Learn one more topic and do exercises. If you got the answer wrong, don’t go directly to the solution with code.
Suggestions and collaborations are more than welcome. Please open an issue or make a PR. 🙂
