Python Pandas - 检查 IntervalArray 中的 Intervals 是否为空
要检查IntervalArray中的Intervals是否为空，请使用Pandas中的array.is_empty属性。
首先，导入所需的库-
import pandas as pd
创建两个Interval对象。使用值为“neither”的“closed”参数设置的开区间-
interval1 = pd.Interval(0, 0, closed='neither') interval2 = pd.Interval(20, 50, closed='neither')
显示间隔-
print("Interval1...\n",interval1)
print("Interval2...\n",interval2)从Interval对象构造一个新的IntervalArray-
array = pd.arrays.IntervalArray([interval1,interval2])
检查IntervalArray中的Intervals是否为空-
print("\nCheck if IntervalArray is empty?\n",array.is_empty)示例
以下是代码-
import pandas as pd
#CreatetwoIntervalobjects
# Open interval set using the "closed" 带值的参数 "neither"
interval1 = pd.Interval(0, 0, closed='neither')
interval2 = pd.Interval(20, 50, closed='neither')
#displaytheintervals
print("Interval1...\n",interval1)
print("Interval2...\n",interval2)
#displaytheintervallength
print("\nInterval1 length...\n",interval1.length)
print("\nInterval2 length...\n",interval2.length)
#ConstructanewIntervalArrayfromIntervalobjects
array = pd.arrays.IntervalArray([interval1,interval2])
#DisplaytheIntervalArray
print("\nOur IntervalArray...\n",array)
#GettingthelengthofIntervalArray
#ReturnsanIndexwithentriesdenotingthelengthofeachIntervalintheIntervalArray
print("\nOur IntervalArray length...\n",array.length)
#CheckiftheIntervalsintheIntervalArrayisempty
print("\nCheck if IntervalArray is empty?\n",array.is_empty)输出结果这将产生以下代码-
Interval1... (0, 0) Interval2... (20, 50) Interval1 length... 0 Interval2 length... 30 Our IntervalArray... <IntervalArray> [(0, 0), (20, 50)] Length: 2, dtype: interval[int64, neither] Our IntervalArray length... Int64Index([0, 30], dtype='int64') Check if IntervalArray is empty? [ True False]
