❮ DataFrame 参考


示例

返回每一列的最小值

import pandas as pd

data = [[10, 18, 11], [13, 15, 8], [9, 20, 3]]

df = pd.DataFrame(data)

print(df.min())
亲自试一试 »

定义和用法

min() 方法返回一个包含每一列最小值的 Series。

通过指定列轴 (axis='columns'), max() 方法会按列搜索并返回每一行的最小值。


语法

dataframe.min(axis, skipna, level, numeric_only, kwargs)

参数

axisskipnalevelnumeric_only 参数是 关键字参数

参数 描述
axis 0
1
'index'
'columns'
可选,检查哪个轴,默认为 0。
skip_na True
False
可选,默认为 True。如果结果不应跳过 NULL 值,则设置为 False。
level 数字
级别名称
可选,默认为 None。指定要沿其检查的级别(在分层多索引中)。
numeric_only None
True
False
可选。指定是否仅检查数值。默认为 None。
kwargs   可选,关键字参数。这些参数没有效果,但可能会被 NumPy 函数接受。

 返回值

一个包含最小值的 Series

如果指定了 level 参数,则此方法将返回一个 DataFrame 对象。

此函数不会更改原始 DataFrame 对象。
