法学Python Pandas - 检查区间是否在左侧、右侧、两侧或均未闭合
要检查区间是否在左侧、右侧、两侧或均未闭合，请使用 interval.closed 属性。
首先，导入所需的库：
import pandas as pd
使用值为“both”的“closed”参数设置闭区间。闭区间（在数学中用方括号表示）包含其端点，例如闭区间 [0, 5] 的特征是 0 <= x <= 5
interval = pd.Interval(left=0, right=20, closed='both')
显示区间
print("Interval...\n",interval)检查区间是否在左侧、右侧、两侧或均未闭合
print("\nChecking for the type of Interval...\n",interval.closed)示例
以下是代码：
import pandas as pd
# Closed interval set using the "closed" parameter with value "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
这将生成以下代码：
Interval... [0, 20] Checking for the type of Interval... both
