Classe « DatetimeIndex »

Méthode pandas.DatetimeIndex.strftime

Signature de la méthode strftime

def strftime(self, date_format) -> 'Index' 

Description

help(DatetimeIndex.strftime)

Convert to Index using specified date_format.

Return an Index of formatted strings specified by date_format, which
supports the same string format as the python standard library. Details
of the string format can be found in `python string format
doc <https://docs.python.org/3/library/datetime.html#strftime-and-strptime-behavior>`__.

Formats supported by the C `strftime` API but not by the python string format
doc (such as `"%R"`, `"%r"`) are not officially supported and should be
preferably replaced with their supported equivalents (such as `"%H:%M"`,
`"%I:%M:%S %p"`).

Note that `PeriodIndex` support additional directives, detailed in
`Period.strftime`.

Parameters
----------
date_format : str
    Date format string (e.g. "%Y-%m-%d").

ndarray[object]
    NumPy ndarray of formatted strings.
