要创建开放时间间隔,请使用并将关闭参数设置为两者都不是。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“两者都不是”的“关闭”参数设置打开间隔。开区间(在数学中用方括号表示)不包含其端点,#即开区间 [0, 5] 的特征在于条件 0 < x < 5:
interval = pd.Interval(left=0, right=20, closed='neither')
显示间隔
print("Interval...\n",interval)
检查间隔中的元素是否存在。这表明 closed = 两者都不包含其端点
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)
以下是代码
import pandas as pd # Open interval set using the "closed" 带值的参数 "neither" # An open interval (in mathematics denoted by square brackets) does not contains its endpoints, # i.e. the open interval [0, 5] is characterized by the conditions 0 < x < 5. interval = pd.Interval(left=0, right=20, closed='neither') # display the interval print("Interval...\n",interval) # display the interval length print("\nInterval length...\n",interval.length) # check for the existence of an element in an Interval # This shows that closed = neither does not contain its endpoints 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
