Python Pandas - 检查给定的 DateOffset 是否已锚定
要检查给定的 DateOffset 是否已锚定,请在 Pandas 中使用 offset.is_anchored() 方法。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。在这里,我们使用锚定偏移,即星期频率,具体为星期二 −
offset = to_offset("W-TUE")显示更新的时间戳 −
print("\nUpdated Timestamp...\n",timestamp + offset)
检查 DateOffset 是否已锚定 −
print("\nCheck whether the DateOffset is anchored...\n", offset.is_anchored())示例
以下是代码 −
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 using the Anchored offset i.e. weekly frequency here for Tuesday
offset = to_offset("W-TUE")
# Display the DateOffset
print("\nDateOffset...\n",offset)
# Display the Updated Timestamp
print("\nUpdated Timestamp...\n",timestamp + offset)
# Check whether the DateOffset is anchored
print("\nCheck whether the DateOffset is anchored...\n", offset.is_anchored())输出
这将生成以下代码 −
Timestamp... 2021-09-26 03:25:02.000045 DateOffset... <Week: weekday=1> Updated Timestamp... 2021-09-28 03:25:02.000045 Check whether the DateOffset is anchored... True
