假设我们有一个Pandas数据帧df,其中有一列名为timestamp,其数据类型为datetime64[ns, UTC],我们希望将其转换为本地时区(例如,'Asia/Shanghai')。 代码语言:txt 复制 import pandas as pd import pytz # 创建示例数据帧 data = { 'timestamp': pd.date_range(start='1/1/2022', periods=...
pandas.to_datetime()函数转换的列的dtype是datetime64 [ns]类型,每个元素都是Timestamp类型。 示例代码: print(df.dtypes) # 查看列的数据类型 print(df['X'][0]) # 访问第一个元素 print(type(df['X'][0])) # 检查元素类型 1. 2. 3. ...

Hello all, I'm trying to convert a datetime64[ns] object to a unix timestamp without an apply. I was wondering if it was the desired behavior to throw an error when trying to do: import pandas as pd import datetime as dt import numpy as ...
new_df= df[df.index >= current_date] df.index是一个datetime64[ns],当我运行代码时,我得到Invalid comparison between dtype=datetime64[ns] and date 解决办法 Pandasdatetime64[ns]不能直接与datetime.date相比。您需要转换: df[df.index >= pd.Timestamp(current_date)]...
cur_date = datetime.today() 今天的约会。我正在检查今天是否在列中: bool_val = cur_date in df['date'] #evaluates to false 我确实知道今天的日期在相关文件中。该系列的 dtype 是 datetime64[ns] 另外,如果重要的话,我只检查日期本身而不是之后的时间戳。我这样做是为了使时间戳为 00:00:00: ...
