Python Pandas - 将IntervalArray中每个区间的左端点作为索引返回
要将IntervalArray中每个区间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)
显示区间:
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 # Create two Interval objects interval1 = pd.Interval(10, 25) interval2 = pd.Interval(15, 70) # display the intervals print("Interval1...\n",interval1) print("Interval2...\n",interval2) # Construct a new IntervalArray from Interval objects array = pd.arrays.IntervalArray([interval1,interval2]) # Display the IntervalArray print("\nOur IntervalArray...\n",array) # Getting the length of IntervalArray # Returns an Index with entries denoting the length of each Interval in the IntervalArray print("\nOur IntervalArray length...\n",array.length) # get the left endpoints print("\nThe left endpoints of each Interval in the IntervalArray as an Index...\n", array.left)
输出
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')
