pandas数据分析基础例子

import numpy as np
import pandas as pd

print(np.arange(10, 100, 10)) #[10 20 30 40 50 60 70 80 90]
print(np.arange(101, 110)) #[101 102 103 104 105 106 107 108 109]

s = pd.Series(
    np.arange(10, 100, 10),
    index=np.arange(101, 110),
    dtype="float"
)

print(s)
"""
101    10.0
