Python Pandas - 从分割数组构建 IntervalArray 并返回每个区间的左端点
要从分割数组构建 IntervalArray,请使用 **pandas.arrays.IntervalArray.from_breaks()**。要返回每个区间的左端点,请使用 **array.left** 属性。
首先,导入所需的库:
import pandas as pd
从类数组的分割构建新的 IntervalArray:
array = pd.arrays.IntervalArray.from_breaks([0, 1, 2, 3, 4, 5])
显示区间:
print("Our IntervalArray...\n",array)
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 # 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) # 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:
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') The left endpoints of each Interval in the IntervalArray as an Index... Int64Index([0, 1, 2, 3, 4], dtype='int64')
