安裝python的包

• conda install package_name
• pip install package_name

更新python的包

jupyter

• 程式碼輸入到In區，在按shift + enter
• 輸出結果展現在out區

匯入約定

• puthon 社群對一些常用模組進行了命名的約定

• • import numpy as np
    import matplotlib.pyplot as plt
    import pandas as pd
    import seaborn as sns
    import statsmodels as sm
    

• • 故np.arrange 是用的是NumPy中的arrange函式

虛擬碼

• 類程式碼，事實上不是實際有效的原始碼

處理/處置/規整（munge/munging/wrangling）

• 將非結構化的或者同時又很凌亂的資料整理成結構化、清晰形式的整個過程

內省

• 直接在jupyter notebook 中的In [n]:行中打？、？？
• • ？一個列印型別，兩個列印原始碼
