Python Pandas - 创建一个封闭的时间间隔并检查两个端点是否存在

要创建闭合时间间隔，请使用并设置闭合参数。要检查两个端点是否存在，请使用in属性。pandas.Interval()

首先，导入所需的库-

import pandas as pd

使用值为“both”的“closed”参数设置的封闭区间。一个闭区间（在数学中用方括号表示）包含它的端点，#即闭区间[0,5]的特征在于条件0<=x<=5

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

显示间隔

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

检查间隔中的元素是否存在。这表明closed=both都包含它的端点

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 # Closed interval set using the "closed" 带值的参数 "both" #Aclosedinterval(inmathematicsdenotedbysquarebrackets)containsitsendpoints, # i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5. interval = pd.Interval(left=0, right=20, closed=both) #displaytheinterval print("Interval...\n",interval) #displaytheinterval length print("\nInterval length...\n",interval.length) #checkfortheexistenceofanelementinanInterval #Thisshowsthatclosed=bothcontainsitsendpoints 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
