Python Pandas - 将IntervalArray中每个区间的中间点作为索引返回


要将IntervalArray中每个区间的中间点作为索引返回,可以使用**array.mid**属性。首先,

首先,导入所需的库:

import pandas as pd

创建两个区间对象。使用值为“both”的“closed”参数设置闭区间:

interval1 = pd.Interval(50, 75, closed='both')
interval2 = pd.Interval(65, 90, closed='both')

显示区间:

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

从区间对象构造一个新的IntervalArray:

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

将IntervalArray中每个区间的中间点作为索引:

print("\nThe midpoint of each interval in the IntervalArray...\n",array.mid)

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, 90, closed='both')

# 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)

# midpoint of each Interval in the IntervalArray as an Index
print("\nThe midpoint of each interval in the IntervalArray...\n",array.mid)

输出

这将产生以下代码:

Interval1...
[50, 75]
Interval2...
[65, 90]

Our IntervalArray...
<IntervalArray>
[[50, 75], [65, 90]]
Length: 2, dtype: interval[int64, both]

Our IntervalArray length...
Int64Index([25, 25], dtype='int64')

The midpoint of each interval in the IntervalArray...
Float64Index([62.5, 77.5], dtype='float64')
