Python Pandas - 返回应用于给定 DateOffset 对象的频率
若要返回应用于给定 DateOffset 对象的频率,请使用 Pandas 中的 offset.freqstr。首先,导入所需的库 −
from pandas.tseries.frequencies import to_offset 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 DateOffset。这里使用“D”频率递增天数 −
offset = to_offset("5D")显示更新的时间戳 −
print("\nUpdated Timestamp...\n",timestamp + offset)
返回应用于给定 DateOffset 对象的频率 −
print("\nThe frequency on the DateOffset object..\n", offset.freqstr)示例
代码如下 −
from pandas.tseries.frequencies import to_offset
import pandas as pd
# Set the timestamp object in Pandas
timestamp = pd.Timestamp('2021-09-26 03:25:02.000045')
# Display the Timestamp
print("Timestamp...\n",timestamp)
# Create the DateOffset
# We are incrementing the days here using the "D" frequency
offset = to_offset("5D")
# Display the DateOffset
print("\nDateOffset...\n",offset)
# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + offset)
# return the frequency applied on the given DateOffset object
print("\nThe frequency on the DateOffset object..\n", offset.freqstr)输出
这将产生以下代码 −
Timestamp... 2021-09-26 03:25:02.000045 DateOffset... <5 * Days> Updated Timestamp... 2021-10-01 03:25:02.000045 The frequency on the DateOffset object.. 5D
