要检查区间是否在左侧、右侧、两者或两者都不闭合，请使用该interval.closed属性。
首先，导入所需的库 -
import pandas as pd
使用值为“both”的“closed”参数设置的封闭区间。一个闭区间（在数学中用方括号表示）包含它的端点，#即闭区间 [0, 5] 的特征在于条件 0 <= x <= 5
interval = pd.Interval(left=0, right=20, closed='both')
显示间隔
print("Interval...\n",interval)检查区间是否在左侧、右侧、两者或两者都不闭合
print("\nChecking for the type of Interval...\n",interval.closed)以下是代码
import pandas as pd
# Closed interval set using the "closed" 带值的参数 "both"
# A closed interval (in mathematics denoted by square brackets) contains its endpoints,
# i.e. the closed interval [0, 5] is characterized by the conditions 0 <= x <= 5.
interval = pd.Interval(left=0, right=20, closed='both')
# display the interval
print("Interval...\n",interval)
# check whether the interval is closed on the left-side, right-side, both or neither
print("\nChecking for the type of Interval...\n",interval.closed)
# check for the existence of an element in an Interval
# This shows that closed = both contains 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] Checking for the type of Interval... both
