python学习教程36-生成一个dataFrame包含三列

import pandas as pd
import numpy as  np

data_range = pd.date_range(start='2021-01-01', periods=1000)

data ={
    'norm': np.random.normal(loc=0, scale=1, size=1000),
    'uniform': np.random.uniform(low=0, high=1, size=1000),
    'binomial':np.random.binomial(n=1, p=0.2, size=1000)
}

df = pd.Dataframe(data=data, index=data_range)
print(df)

 打印输出：
