Python Pandas -检查区间是否右边是闭合的

要检查区间是否左边是闭合的，请使用 interval.closed_right 属性。首先，导入所需的库 –

import pandas as pd

使用”value”参数为“right”的“closed”参数设置的区间，即[0,5），当closed =’right’时，0＜x≤5描述了该区间。

interval = pd.Interval(left = 0, right = 20, closed = 'right')

显示区间

print("Interval...\n",interval)

检查区间是否右闭

print("\nChecking whether the Interval is closed on the right...\n", interval.closed_right)

示例

以下是代码

import pandas as pd

# Interval set using the "closed" parameter with value "right"
# i.e. [0, 5) is described by 0 < x <= 5 when closed='right'
interval = pd.Interval(left=0, right=20, closed='right')

# display the interval
print("Interval...\n",interval)

# display the interval length
print("\nInterval length...\n",interval.length)

# check whether the interval is closed on the right-side
print("\nChecking whether the Interval is closed on the right...\n", interval.closed_right)

# check for the existence of an element in an Interval
# This shows that closed = right contain only the right-most endpoint
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

这将产生以下代码

Interval...
(0, 20]

Interval length...
20

Checking whether the Interval is closed on the right...
True
