python Pandas - 将 IntervalArray 中每个 Interval 的左端点作为索引返回

要将IntervalArray中每个Interval的左端点作为索引返回，请使用array.left属性。

首先，导入所需的库-

import pandas as pd

创建两个Interval对象-

nterval1 = pd.Interval(10, 25) interval2 = pd.Interval(15, 70)

显示间隔-

print("Interval1...\n",interval1) print("Interval2...\n",interval2)

从Interval对象构造一个新的IntervalArray-

array = pd.arrays.IntervalArray([interval1,interval2])

获取左端点-

print("\nThe left endpoints of each Interval in the IntervalArray as an Index...\n", array.left)

示例

以下是代码-

import pandas as pd #创建两个Interval对象 interval1 = pd.Interval(10, 25) interval2 = pd.Interval(15, 70) #显示间隔 print("Interval1...\n",interval1) print("Interval2...\n",interval2) #从Interval对象构造一个新的IntervalArray array = pd.arrays.IntervalArray([interval1,interval2]) #显示间隔数组 print("\nOur IntervalArray...\n",array) #获取IntervalArray的长度 #返回一个索引，其中的条目表示IntervalArray中每个Interval的长度 print("\nOur IntervalArray length...\n",array.length) #获取左端点 print("\nThe left endpoints of each Interval in the IntervalArray as an Index...\n", array.left)输出结果

这将产生以下代码-

Interval1... (10, 25] Interval2... (15, 70] Our IntervalArray... <IntervalArray> [(10, 25], (15, 70]] Length: 2, dtype: interval[int64, right] Our IntervalArray length... Int64Index([15, 55], dtype=int64) The left endpoints of each Interval in the IntervalArray as an Index... Int64Index([10, 15], dtype=int64)
