pandas学习笔记

一、基础语法

基础语法参考菜鸟教程：https://www.runoob.com/pandas/pandas-tutorial.html

二、实用案例

2.1 通过pd.DataFrame的plot方法快速绘制曲线

# jupyter
import pandas as pd
import matplotlib
from matplotlib import pyplot as plt
import numpy as np

matplotlib.use('TkAgg')

data = {
    'timestamp': [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
    'a': np.random.rand(10),
    'b': np.random.rand(10),
    'c': np.random.rand(10),
    'd': np.random.rand(10),
    'e': np.random.rand(10)
}

pf = pd.DataFrame(data)

%matplotlib inline
pf.plot(x='timestamp', y=['a', 'b', 'c', 'd', 'e'])
