Pandas Python - 检查闭合区间是否为空
若要检查一个双闭合区间是否为空,请使用 **interval.is_empty 属性**。首先导入所需的库 -
import pandas as pd
双闭合区间。使用具有 “both” 值的 “closed” 参数设置区间
interval = pd.Interval(0, 0, closed='both')
显示区间
print("Interval...\n",interval)
当一个区间双闭合的时候,检查该区间是否为空。只包含一个点的区间不为空,即返回 False。
print("\nIs Interval empty? \n",interval.is_empty)
示例
代码如下所示
import pandas as pd # interval closed from the both sides # Interval set using the "closed" parameter with value "both" interval = pd.Interval(0, 0, closed='both') # display the interval print("Interval...\n",interval) # display the interval length print("\nInterval length...\n",interval.length) # check whether interval is empty when it is closed from both sides # An Interval that contains a single point is not empty i.e. False is returned print("\nIs Interval empty? \n",interval.is_empty)
输出
这将生成以下代码
Interval... [0, 0] Interval length... 0 Is Interval empty? False
