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
