您可以在dataframe列上使用apply函数将必要的列转换为String。例如：
1.把datetime转成字符串: 2017-11-23 17:05:18 2.把字符串转成datetime: 2017-11-23 16:10:...
在Pandas中,你可以通过多种方式创建datetime64对象。以下是一些常见的创建方法: python import pandas as pd # 从字符串创建datetime64对象 date_string = '2023-10-23' date = pd.to_datetime(date_string) print(date) # 输出: 2023-10-23 00:00:00 # 从整数(Unix时间戳)创建datetime64对象 timestamp ...
datetime64[ns] 在上述示例中,我们首先创建了一个包含日期字符串的列表。然后,使用pd.to_datetime()函数将该列表中的对象类型转换为datetime64类型。最后,通过打印转换后的数据类型,可以看到数据已成功转换为datetime64类型。 推荐的腾讯云相关产品:腾讯云数据库TDSQL、腾讯云云服务器CVM、腾讯云对象存储COS。
DatetimeIndex(['2023-01-01', '2023-02-01', '2023-03-01'], dtype='datetime64[ns]', freq=None) 1. 示例二:将时间戳序列转化为datetime 时间戳通常表示某个特定时间点的秒数或毫秒数。我们也可以借助pd.to_datetime函数将时间戳序列转换为datetime对象。以下是相关代码示例: ...
pd.to_datetime(datestrs) # datetimeindex(['2011-07-06 12:00:00', '2011-08-06 00:00:00'], dtype='datetime64[ns]', freq=none) 1. 2. 3. 4. 5. 6. 7. 8. 4. timedelta timedelta 可以表示两个时间之间的时间差: dtm.timedelta(days=0, seconds=0, microseconds=0, milliseconds=0, ...
