Python Pandas - 如果索引单调递增（仅相等或递增）值，则返回

要返回索引是否单调递增（仅相等或递增）的值，请使用index.is_monotonic_increasing属性。

首先，导入所需的库-

import pandas as pd

创建索引-

index = pd.Index([10, 20, 20, 30, 40])

显示索引-

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

检查索引是否单调递增-

print("\nIs the Pandas index monotonic increasing?\n",index.is_monotonic_increasing)

示例

以下是代码-

import pandas as pd #创建索引 index = pd.Index([10, 20, 20, 30, 40]) #显示索引 print("Pandas Index...\n",index) #返回一个表示索引中数据的数组 print("\nArray...\n",index.values) #检查索引是否单调递增 print("\nIs the Pandas index monotonic increasing?\n",index.is_monotonic_increasing)输出结果

这将产生以下代码-

Pandas Index... Int64Index([10, 20, 20, 30, 40], dtype=int64) Array... [10 20 20 30 40] Is the Pandas index monotonic increasing? True
