Python Pandas - 检查 DateOffset 值是否已规范化
要检查DateOff设置值是否已规范化，请使用offset.normalizePandas中的属性。
首先，导入所需的库-
from pandas.tseries.offsets import DateOffset import pandas as pd
在Pandas中设置时间戳对象-
timestamp = pd.Timestamp('2021-09-26 03:25:02.000045')创建日期偏移量。使用“months”参数在此处增加月份。我们使用“normalize”参数对DateOffset进行了标准化-
offset = pd.tseries.offsets.DateOffset(months=4, normalize=True)
显示更新的时间戳-
print("\nUpdated Timestamp...\n",timestamp + offset)检查DateOffset是否标准化-
print("\nThe DateOffset is normalized..\n", offset.normalize)示例
以下是代码-
from pandas.tseries.offsets import DateOffset
import pandas as pd
#在Pandas中设置时间戳对象
timestamp = pd.Timestamp('2021-09-26 03:25:02.000045')
#显示时间戳
print("Timestamp...\n",timestamp)
#创建日期偏移
# Incrementing the months here using the "months" parameter
# We have normalized the DateOffset using the "normalize" parameter
offset = pd.tseries.offsets.DateOffset(months=4, normalize=True)
#显示日期偏移
print("\nDateOffset...\n",offset)
#显示更新的时间戳
print("\nUpdated Timestamp...\n",timestamp + offset)
#检查DateOffset是否标准化
print("\nThe DateOffset is normalized..\n", offset.normalize)输出结果这将产生以下代码-
Timestamp... 2021-09-26 03:25:02.000045 DateOffset... <DateOffset: months=4> Updated Timestamp... 2022-01-26 00:00:00 The DateOffset is normalized.. True
