Python Pandas – 返回一个Index，该Index以IntervalArray中每个Interval的长度为条目

要返回一个Index，其中每个条目表示IntervalArray中每个Interval的长度，请使用 array.length 属性。

首先，导入所需的库 −

import pandas as pd

创建两个Interval对象。使用值为“both”的“closed”参数设置封闭间隔 −

interval1 = pd.Interval(50, 75, closed='both')
interval2 = pd.Interval(65, 95, closed='both')

构造一个新的IntervalArray，来自Interval对象 −

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

显示IntervalArray −

print("\n我们的IntervalArray...\n",array)

获取IntervalArray的长度。返回一个Index，该Index以IntervalArray中每个Interval的长度为条目 −

print("\n我们的IntervalArray长度...\n",array.length)

示例

以下是代码 −

import pandas as pd

# Create two Interval objects
# Closed intervals set using the "closed" parameter with value "both"
interval1 = pd.Interval(50, 75, closed='both')
interval2 = pd.Interval(65, 95, closed='both')

# display the intervals
print("Interval1...\n",interval1)
print("Interval2...\n",interval2)

# display the interval length
print("\nInterval1长度...\n",interval1.length)
print("\nInterval2长度...\n",interval2.length)

# Construct a new IntervalArray from Interval objects
array = pd.arrays.IntervalArray([interval1,interval2])

# Display the IntervalArray
print("\n我们的IntervalArray...\n",array)

# Getting the length of IntervalArray
# Returns an Index with entries denoting the length of each Interval in the IntervalArray
print("\n我们的IntervalArray长度...\n",array.length)

输出

这将产生以下代码 −

Interval1...
[50, 75]
Interval2...
[65, 95]

Interval1长度...
25

Interval2长度...
30

我们的IntervalArray...
<IntervalArray>
[[50, 75], [65, 95]]
Length: 2, dtype: interval[int64, both]

我们的IntervalArray长度...
Int64Index([25, 30], dtype='int64')
