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')
