pandas 的2名字来源是 pannel data

安装python的包

• conda install package_name
• pip install package_name

更新python的包

• conda update package_name
• pip install --upgraade package_name

我觉得conda好用多了，能用conda绝对不用原生

jupyter

• 代码输入到In区，在按shift + enter
• 输出结果展现在out区

导入约定

• puthon 社区对一些常用模块进行了命名的约定

• • 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函数

伪代码

• 类代码，事实上不是实际有效的源代码

处理/处置/规整（munge/munging/wrangling）

• 将非结构化的或者同时又很凌乱的数据整理成结构化、清晰形式的整个过程

内省

• 直接在jupyter notebook 中的In [n]:行中打？、？？
• • ？一个打印类型，两个打印源代码
