Python Pandas - 检查区间是否在左侧开放
要检查区间是否在左侧开启,请使用 interval.open_left 属性。首先,导入所需的库 -
import pandas as pd
使用值为“neither”的“closed”参数设置开放区间。开放区间(在数学中用方括号表示)不包含其端点,即开放区间 [0, 5] 的特征是条件 0 < x < 5
interval = pd.Interval(5, 20, closed='neither')
显示区间
print("Interval...\n",interval)
检查区间是否在左侧开启
print("\nCheck if the interval is open on the left side...\n",interval.open_left)
示例
以下是代码
import pandas as pd # Open interval set using the "closed" parameter with value "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(5, 20, closed='neither') # display the interval print("Interval...\n",interval) # the left bound print("\nThe left bound for the Interval...\n",interval.left) # the right bound print("\nThe right bound for the Interval...\n",interval.right) # display the interval length print("\nInterval length...\n",interval.length) # check whether the interval is open on the left side print("\nCheck if the interval is open on the left side...\n",interval.open_left)
输出
这将生成以下代码
Interval... (5, 20) The left bound for the Interval... 5 The right bound for the Interval... 20 Interval length... 15 Check if the interval is open on the left side... True
