Python strftime() function

In Python, date and time are not a data type of its own, but a module named datetime can be imported to work with the date as well as time. Datetime module comes built into Python, so there is no need to install it externally. The datetime module in Python provides classes with numerous functions to deal with date and time.

The strftime() function is used to convert date and time objects to their string representation. It takes one or more input of formatted code and returns the string representation.

Syntax :

strftime(format)

Returns : It returns the string representation of the date or time object.

List of format codes : Reference table for the format codes.
