Invalid DATE, DATETIME, or TIMESTAMP values are converted to the “zero” value of the appropriate type ('0000-00-00' or '0000-00-00 00:00:00'), if the SQL mode permits this conversion. The precise behavior depends on which if any of strict SQL mode and the NO_ZERO_DATE SQL mode...

1 Python提供了多个内置模块用于操作日期时间,像calendar,time,datetime。time模块我在之前的文章已经有所介绍,它提供的接口与C标准库time.h基本一致。相比于time模块,datetime模块的接口则更直观、更容易调用 2 datetime中包含三个类date ,time,datetime 函数datetime.combine(date,time)可以得到dateime datetime.date()...

Pandas 中默认的时间/日期类型是由pd.Timestamp()函数转换的来的,该函数能够表示的时间范围是1678-01-01 00:00:00——2262-04-11 23:47:16,因此不在此时段内的时间数据都会被视作异常值。而 Python 中的标准库datetime下的datetime.datetime()函数也可以进行时间/日期转换,支持的时间范围是0001-01-01 00:00...
