Python Pandas - 创建半封闭时间间隔并检查端点是否存在

要创建半闭合时间间隔，请使用并将闭合参数设置为右侧。要检查端点是否存在，请使用in属性。pandas.Interval()

首先，导入所需的库-

import pandas as pd

使用值为“right”的“closed”参数设置半封闭区间。半封闭即(0,5]由0<x<=5(closed=right)描述

interval = pd.Interval(left=0, right=20, closed=right)

显示间隔

print("Interval...\n",interval)

检查间隔中的元素是否存在。这表明closed=right只包含最右边的端点

print("\nThe left-most element exists in the Interval? = \n",0 in interval) print("\nThe right-most element exists in the Interval? = \n",20 in interval)

示例

以下是代码

import pandas as pd # Half-Closed interval set using the "closed" 带值的参数 "right" # Half-Closed i.e. (0, 5] is described by 0 < x <= 5 (closed=right). interval = pd.Interval(left=0, right=20, closed=right) #displaytheinterval print("Interval...\n",interval) #displaytheinterval length print("\nInterval length...\n",interval.length) #checkfortheexistenceofanelementinanInterval #Thisshowsthatclosed=rightcontainonlytheright-mostendpoint print("\nThe left-most element exists in the Interval? = \n",0 in interval) print("\nThe right-most element exists in the Interval? = \n",20 in interval)输出结果

这将产生以下代码

Interval... (0, 20] Interval length... 20
