使用函数：

def min_max_series(series):
    return (series - series.min()) / (series.max() - series.min())

传入一个pandas.Series数据即可

案例

import pandas as pd


def min_max_series(series):
    return (series - series.min()) / (series.max() - series.min())


print(min_max_series(pd.Series([1, 2, 3, 4, 5, 3.3, 4.2])))
