日期时间对象 ¶

Various date and time objects are supplied by the datetime module. Before using any of these functions, the header file datetime.h must be included in your source (note that this is not included by Python.h ), and the macro PyDateTime_IMPORT must be invoked, usually as part of the module initialisation function. The macro puts a pointer to a C structure into a static variable, PyDateTimeAPI , that is used by the following macros.

Type-check macros:

int PyDate_Check ( PyObject  *ob ) ¶

返回 True 若 ob 是类型 PyDateTime_DateType 或子类型的 PyDateTime_DateType . ob 必须不是 NULL .

int PyDateTime_Check ( PyObject  *ob ) ¶

返回 True 若 ob 是类型 PyDateTime_DateTimeType 或子类型的 PyDateTime_DateTimeType . ob 必须不是 NULL .

int PyDateTime_CheckExact ( PyObject  *ob ) ¶

返回 True 若 ob 是类型 PyDateTime_DateTimeType . ob 必须不是 NULL .

int PyTime_Check ( PyObject  *ob ) ¶

返回 True 若 ob 是类型 PyDateTime_TimeType 或子类型的 PyDateTime_TimeType . ob 必须不是 NULL .

int PyTime_CheckExact ( PyObject  *ob ) ¶

int PyDelta_Check ( PyObject  *ob ) ¶

返回 True 若 ob 是类型 PyDateTime_DeltaType 或子类型的 PyDateTime_DeltaType . ob 必须不是 NULL .

int PyDelta_CheckExact ( PyObject  *ob ) ¶

Macros to create objects:

PyObject * PyDate_FromDate ( int  year , int  month , int  day ) ¶

返回值：新引用。

返回 datetime.date object with the specified year, month and day.

PyObject * PyDateTime_FromDateAndTime ( int  year , int  month , int  day , int  hour , int  minute , int  second , int  usecond ) ¶

返回值：新引用。

返回 datetime.datetime object with the specified year, month, day, hour, minute, second and microsecond.

PyObject * PyTime_FromTime ( int  hour , int  minute , int  second , int  usecond ) ¶

返回值：新引用。

返回 datetime.time object with the specified hour, minute, second and microsecond.

PyObject * PyDelta_FromDSU ( int  days , int  seconds , int  useconds ) ¶

返回值：新引用。

返回 datetime.timedelta object representing the given number of days, seconds and microseconds. Normalization is performed so that the resulting number of microseconds and seconds lie in the ranges documented for datetime.timedelta 对象。

Macros to extract fields from date objects. The argument must be an instance of PyDateTime_Date , including subclasses (such as PyDateTime_DateTime ). The argument must not be NULL , and the type is not checked:

int PyDateTime_GET_YEAR ( PyDateTime_Date  *o ) ¶

int PyDateTime_GET_MONTH ( PyDateTime_Date  *o ) ¶

Return the month, as an int from 1 through 12.

int PyDateTime_GET_DAY ( PyDateTime_Date  *o ) ¶

Return the day, as an int from 1 through 31.

Macros to extract fields from datetime objects. The argument must be an instance of PyDateTime_DateTime , including subclasses. The argument must not be NULL , and the type is not checked:

int PyDateTime_DATE_GET_HOUR ( PyDateTime_DateTime  *o ) ¶

Return the hour, as an int from 0 through 23.

int PyDateTime_DATE_GET_MINUTE ( PyDateTime_DateTime  *o ) ¶

Return the minute, as an int from 0 through 59.

int PyDateTime_DATE_GET_SECOND ( PyDateTime_DateTime  *o ) ¶

Return the second, as an int from 0 through 59.

int PyDateTime_DATE_GET_MICROSECOND ( PyDateTime_DateTime  *o ) ¶

Return the microsecond, as an int from 0 through 999999.

Macros to extract fields from time objects. The argument must be an instance of PyDateTime_Time , including subclasses. The argument must not be NULL , and the type is not checked:

int PyDateTime_TIME_GET_HOUR ( PyDateTime_Time  *o ) ¶

Return the hour, as an int from 0 through 23.

int PyDateTime_TIME_GET_MINUTE ( PyDateTime_Time  *o ) ¶

int PyDateTime_TIME_GET_SECOND ( PyDateTime_Time  *o ) ¶

Return the second, as an int from 0 through 59.

int PyDateTime_TIME_GET_MICROSECOND ( PyDateTime_Time  *o ) ¶

Return the microsecond, as an int from 0 through 999999.

Macros to extract fields from time delta objects. The argument must be an instance of PyDateTime_Delta , including subclasses. The argument must not be NULL , and the type is not checked:

int PyDateTime_DELTA_GET_DAYS ( PyDateTime_Delta  *o ) ¶

Return the number of days, as an int from -999999999 to 999999999.
