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')
