Jupyter 測試網頁上提供了經典的 Jupyter Notebook 與新版的 JupyterLab 兩種介面 :
其中 JupyterLab 是 Notebook 的下一代產品, 除了將原有 Notebook 的功能整合在一起外還加進了更多新功能, 參考 :
# Jupyterlab：超強的下一代Jupyter Notebook
# Python 學習筆記 : 安裝 SymPy 套件
# Jupyter Notebook 介紹 ＆安裝方式
# [Day02]使用 Jupyter notebook來寫python
# Jupyter Notebook 使用技巧彙整：建置不同程式語言的核心
JupyterLab 說明文件參考 GitHub :
# https://github.com/jupyterlab/jupyterlab
除了使用方便的線上版外, 也可以在本機中安裝 JupyterLab 以避免網路不通時無法使用了. 安裝方式很簡單, 就是直接用 pip3 安裝 jupyterlab 套件 :
pip3 install jupyterlab
D:\>pip3 install jupyterlab

可見 JupyterLab 的相依模組很多, 但其實主程式不大, 全部加起來應該沒超過 20MB.
安裝好後在命令列下輸入 jupyter lab (有空格) 即可 :

它會以網址 http://localhost:8888/lab 開啟預設瀏覽器網頁, 可用 Notebook 或 JupyterLab :
點選右邊的 JupyterLab 進去再點選 Python 3 :
輸入 Sympy 的積分式 :
果然繪製出美美的積分式了.
