要检查从左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
间隔从左侧关闭。使用值为“left”的“closed”参数设置的间隔
interval = pd.Interval(0, 0, closed='left')
显示间隔
print("Interval...\n",interval)检查间隔是否为空
print("\nIs Interval empty? \n",interval.is_empty)以下是代码
import pandas as pd
# 从左边闭合的区间
# Interval set using the "closed" 带值的参数 "left"
interval = pd.Interval(0, 0, closed='left')
# 显示间隔
print("Interval...\n",interval)
# 显示间隔 length
print("\nInterval length...\n",interval.length)
# 检查间隔是否为空
print("\nIs Interval empty? \n",interval.is_empty)输出结果这将产生以下代码
Interval... [0, 0) Interval length... 0 Is Interval empty? True
