Python Pandas IntervalIndex - 检查包含点的区间是否为空

要检查包含点的区间是否为空，请使用Pandas中的IntervalIndex.is_empty属性。

首先，导入所需的库-

import pandas as pd

创建间隔索引-

interval = pd.IntervalIndex.from_arrays([0, 1], [1, 2], closed=right)

显示间隔-

print("IntervalIndex...\n",interval)

检查包含点的区间是否为空-

print("\nIs the interval empty?\n",interval.is_empty)

示例

以下是代码-

import pandas as pd #创建间隔索引 interval = pd.IntervalIndex.from_arrays([0, 1], [1, 2], closed=right) #显示间隔 print("IntervalIndex...\n",interval) #显示间隔 length print("\nIntervalIndex length...\n",interval.length) #检查包含点的区间是否为空 print("\nIs the interval empty?\n",interval.is_empty)输出结果

这将产生以下输出-

IntervalIndex... IntervalIndex([(0, 1], (1, 2]], dtype=interval[int64, right]) IntervalIndex length... Int64Index([1, 1], dtype=int64) Is the interval empty? [False False]
