Python Pandas - 检查区间是否在左侧、右侧、两者或两者都不闭合

要检查区间是否在左侧、右侧、两者或两者都不闭合，请使用该interval.closed属性。

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)

检查区间是否在左侧、右侧、两者或两者都不闭合

print("\nChecking for the type of Interval...\n",interval.closed)

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) #checkwhethertheintervalisclosedontheleft-side,right-side,bothorneither print("\nChecking for the type of Interval...\n",interval.closed) #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] Checking for the type of Interval... both
