法学研究Python Pandas CustomBusinessHour——检查给定的时间戳是否为偏移量
要检查给定的时间戳是否为偏移量，请在 Pandas 中使用 CustomBusinessHour.is_on_offset()。传递该时间戳作为要检查的参数。
首先，导入所需的库 −
import pandas as pd
在 Pandas 中设置时间戳对象 −
timestamp = pd.Timestamp('2021-11-14 05:20:30')
创建 CustomBusinessHour 偏移量。CustomBusinessHour 是 DateOffset 子类 −
cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:30")
将偏移量添加到时间戳并显示更新后的时间戳
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
检查给定的时间戳是否为偏移量 −
offset = cbhOffset.is_on_offset(pd.Timestamp('2021-11-20 05:20:30'))显示结果 −
print("\nCheck if the given timestamp is on offset or not...\n",offset)
示例
以下是代码 −
import pandas as pd
# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-11-14 05:20:30')
# Display the Timestamp
print("Timestamp...\n",timestamp)
# Create the CustomBusinessHour Offset
# CustomBusinessHour is the DateOffset subclass
# Here, "start" is the start time of your custom business hour in 24h format.
# The "end" is the end time of your custom business hour in 24h format.
cbhOffset = pd.tseries.offsets.CustomBusinessHour(start="09:30", end = "18:30")
# Display the CustomBusinessHour Offset
print("\nCustomBusinessHour Offset...\n",cbhOffset)
# Add the offset to the Timestamp and display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + cbhOffset)
# Check if the given timestamp is on offset or not
offset = cbhOffset.is_on_offset(pd.Timestamp('2021-11-20 05:20:30'))
# display the result
print("\nCheck if the given timestamp is on offset or not...\n",offset)输出
这将生成以下代码 −
Timestamp... 2021-11-14 05:20:30 CustomBusinessHour Offset... <CustomBusinessHour: CBH=09:30-18:30> Updated Timestamp... 2021-11-15 10:30:00 Check if the given timestamp is on offset or not... False
