Python Pandas - 检查左侧的区间是否打开
要检查间隔是否在左侧打开，请使用interval.open_left属性。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(5, 20, closed='neither')
显示间隔
print("Interval...\n",interval)检查左侧的区间是否打开
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" 带值的参数 "neither"
#Anopeninterval(inmathematicsdenotedbysquarebrackets)doesnotcontainsitsendpoints,
# i.e. the open interval [0, 5] is characterized by the conditions 0 < x < 5.
interval = pd.Interval(5, 20, closed='neither')
#displaytheinterval
print("Interval...\n",interval)
#theleftbound
print("\nThe left bound for the Interval...\n",interval.left)
#therightbound
print("\nThe right bound for the Interval...\n",interval.right)
#displaytheinterval length
print("\nInterval length...\n",interval.length)
#checkwhethertheintervalisopenontheleftside
print("\nCheck if the interval is open on the left side...\n",interval.open_left)输出结果这将产生以下代码
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
