Python Pandas - 检查 CustomBusinessDay Offset 是否已规范化
要检查 CustomBusinessDay Offset 是否已标准化，请使用CustomBusinessDay.normalizePandas 中的属性。
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('2021-10-22 03:10:35')创建 CustomBusinessDay 偏移量。CustomBusinessDay 是 DateOffset 子类，表示不包括假期的自定义工作日。有效工作日的周掩码。我们使用“normalize”参数标准化了 CustomBusinessDay -
cbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri', normalize=True)
将偏移量添加到时间戳并显示更新的时间戳 -
print("\nUpdated Timestamp...\n",timestamp + cbdOffset)检查 CustomBusinessDay Offset 是否标准化 -
print("\nThe CustomBusinessDay Offset is normalized ?\n", cbdOffset.normalize)示例
以下是代码 -
import pandas as pd# Set the timestamp object in Pandastimestamp = pd.Timestamp('2021-10-22 03:10:35')# Display the Timestampprint("Timestamp...\n",timestamp)# Create the CustomBusinessDay Offset# CustomBusinessDay is the DateOffset subclass representing custom business days excluding holidays# Weekmask of valid business days# We have normalized the CustomBusinessDay using the "normalize" parametercbdOffset = pd.tseries.offsets.CustomBusinessDay(n = 2, weekmask = 'Mon Tue Wed Fri', normalize=True)# Display the CustomBusinessDay Offsetprint("\nCustomBusinessDay Offset...\n",cbdOffset)# Add the offset to the Timestamp and display the Updated Timestampprint("\nUpdated Timestamp...\n",timestamp + cbdOffset)# Return frequency applied on the given CustomBusinessDay Offset object as a stringprint("\nFrequency applied on the given CustomBusinessDay Offset object...\n",cbdOffset.freqstr)# check whether the CustomBusinessDay Offset is normalized or notprint("\nThe CustomBusinessDay Offset is normalized ?\n", cbdOffset.normalize)输出结果
这将产生以下代码 -
Timestamp... 2021-10-22 03:10:35CustomBusinessDay Offset... <2 * CustomBusinessDays>Updated Timestamp... 2021-10-26 00:00:00Frequency applied on the given CustomBusinessDay Offset object... 2CThe CustomBusinessDay Offset is normalized ? True
