Python Pandas - 如果从两侧关闭，检查间隔是否为空

要检查从两侧关闭的区间是否为空，请使用interval.is_empty 属性。首先，导入所需的库 -

import pandas as pd

间隔从两侧关闭。使用值为“both”的“closed”参数设置的间隔

interval = pd.Interval(0, 0, closed='both')

显示间隔

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

从两边关闭时检查interval是否为空。包含单个点的区间不为空，即返回 False

print("\nIs Interval empty? \n",interval.is_empty)

示例

以下是代码

import pandas as pd

# interval closed from the both sides
# Interval set using the "closed" 带值的参数 "both"
interval = pd.Interval(0, 0, closed='both')

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

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

# check whether interval is empty when it is closed from both sides
# An Interval that contains a single point is not empty i.e. False is returned
print("\nIs Interval empty? \n",interval.is_empty)

这将产生以下代码

Interval...
[0, 0]

Interval length...
0

Is Interval empty?
False
