Python Pandas - 根据分隔数组构造 IntervalArray


要根据分隔数组构造一个 IntervalArray,可以使用 pandas.arrays.IntervalArray.from_breaks()

首先,导入必需的函数库:-

import pandas as pd

根据一个类数组的分隔构造一个新的 IntervalArray:-

array = pd.arrays.IntervalArray.from_breaks([0, 1, 2, 3, 4, 5])

显示这些区间:-

print("Our IntervalArray...\n",array)

获取 IntervalArray 的长度:-

print("\nOur IntervalArray length...\n",array.length)

示例

以下为代码:-

import pandas as pd

# Construct a new IntervalArray from an array-like of splits
array = pd.arrays.IntervalArray.from_breaks([0, 1, 2, 3, 4, 5])

# Display the IntervalArray
print("Our 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

将生成以下代码:-

Our IntervalArray...
<IntervalArray>
[(0, 1], (1, 2], (2, 3], (3, 4], (4, 5]]
Length: 5, dtype: interval[int64, right]

Our IntervalArray length...
Int64Index([1, 1, 1, 1, 1], dtype='int64')

The midpoint of each interval in the IntervalArray...
Float64Index([0.5, 1.5, 2.5, 3.5, 4.5], dtype='float64')
