Python Pandas - 从元组数组构造 IntervalArray 并返回每个区间的左端点


要从类似数组的元组构造 IntervalArray,请使用 **pandas.arrays.IntervalArray.from_tuples()** 方法。要返回 IntervalArray 中每个区间的左端点,请使用 **array.left** 属性。

首先,导入所需的库:

import pandas as pd

从类似数组的元组构造一个新的 IntervalArray:

array = pd.arrays.IntervalArray.from_tuples([(10, 25),(15, 70)])

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 tuples
array = pd.arrays.IntervalArray.from_tuples([(10, 25),(15, 70)])

# 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>
[(10, 25], (15, 70]]
Length: 2, dtype: interval[int64, right]

Our IntervalArray length...
Int64Index([15, 55], dtype='int64')

The midpoint of each interval in the IntervalArray...
Float64Index([17.5, 42.5], dtype='float64')

The left endpoints of each Interval in the IntervalArray as an Index...
Int64Index([10, 15], dtype='int64')
