Python Dates and Times in Python (2014) Dates and Times strftime & strptime

In python shell my timestrings.py script is working

why I`m getting Bummer!

## Examples
# to_string(datetime_object) => "24 September 2012"
# from_string("09/24/12 18:30", "%m/%d/%y %H:%M") => datetime
import datetime
def to_string(date):
    day = datetime.datetime.strptime(date, '%d %B %Y')

    return day.strftime('%d %B %Y')

I would expect this to always cause a TypeError.

The function*strptime* takes two string arguments, but you're providing with a datetime as the first argument.

You didn't say which task you were working on, perhaps you already passed task 1 and started working on task 2? But if so, you don't have two separate functions yet and you have some work to do with the arguments.

If you're still on task 1, you have too much code, and you should not need strptime at all.

Hi Andrey,

The argument passed into the function is already a datetime object, not a string, so you don't need to use the .strptime() method. You only need to use .strftime() directly on the object.

def to_string(datetime_object):
    return datetime_object.strftime('%d %B %Y')

Also, just a quick note that the word "date" is a reserved word in the datetime library. It is best to try to avoid using it as a variable name. It may not cause any problems in simple cases, but when working with dates and times you don't want to confuse a variable named "date" with the date object.

Good Luck.

It may not be entirely accurate to refer to "date" as a reserved word.

A reserved word would normally only be something intrinsic to the language itself, such as def or class.

Steven and Ryan, Thanks for highlighting these points!!! Really good help! Thanks again

Ah good point, Steven. My terminology is incorrect.
