Python Pandas - 创建半开时间间隔并检查端点是否存在

要创建半开时间间隔，请使用并将关闭参数设置为左。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“left”的“closed”参数设置半开间隔。半开即[0,5)被描述为0<=x<5whenclosed=left

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

显示间隔

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

检查间隔中的元素是否存在。这表明closed=left只包含最左边的端点

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-Open interval set using the "closed" 带值的参数 "left" # Half-open i.e. [0, 5) is described by 0 <= x < 5 when closed=left interval = pd.Interval(left=0, right=20, closed=left) #displaytheinterval print("Interval...\n",interval) #displaytheinterval length print("\nInterval length...\n",interval.length) #checkfortheexistenceofanelementinanInterval #Thisshowsthatclosed=leftcontainonlytheleft-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
