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
