Python - 为区间数据创建 Pandas 数组


要为区间数据创建 Pandas 数组,请使用 pandas.arrays.IntervalArray() 方法。首先,导入所需的库 −

import pandas as pd

创建两个 Interval 对象 −

interval1 = pd.Interval(10, 30)
interval2 = pd.Interval(30, 70)

显示区间 −

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

从 Interval 对象构建一个新的 IntervalArray −

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

示例

以下为代码 −

import pandas as pd

# Create two Interval objects
interval1 = pd.Interval(10, 30)
interval2 = pd.Interval(30, 70)

# 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)

输出

将生成以下代码 −

Interval1...
(10, 30]
Interval2...
(30, 70]

Our IntervalArray...
<IntervalArray>
[(10, 30], (30, 70]]
Length: 2, dtype: interval[int64, right]

Our IntervalArray length...
Int64Index([20, 40], dtype='int64')
