Python - 返回 Pandas 索引的最大值

要返回 Pandas 索引的最大值，请使用 index.max() 方法。首先，导入所需的库 -

import pandas as pd

创建 Pandas 索引

index = pd.Index([10, 20, 70, 40, 90, 50, 25, 30])

显示 Pandas 索引 −

print("Pandas Index...\n",index)

获取最大值 −

print("\nMaximum value..\n", index.max())

示例

以下为代码 −

import pandas as pd

# Creating Pandas index
index = pd.Index([10, 20, 70, 40, 90, 50, 25, 30])

# Display the Pandas index
print("Pandas Index...\n",index)

# Return the number of elements in the Index
print("\nNumber of elements in the index...\n",index.size)

# Return the dtype of the data
print("\nThe dtype object...\n",index.dtype)

# get the maximum value
print("\nMaximum value..\n", index.max())

输出

将产生以下输出 −

Pandas Index...
Int64Index([10, 20, 70, 40, 90, 50, 25, 30], dtype='int64')

Number of elements in the index...
8

The dtype object...
int64

Maximum value..
90
