improving get method

[aster94]

hello,
i would like to ask for a new feature which is present in other library which manages times, for example in moment
in that module i can do something like
moment.date(d)
where d is 01/01/2001 or 1/1/2001 or 01/01/01 or 01-01-2001
i am trying to say that it accept quite everything, it would be nice if get() was able to be feed with everything too

here there is a code snippet if you want to try

import arrow, moment

d = ["01/01/2001", "2/2/2002", "03/03/03", "04-04-2004"]
for item in d:
    m = moment.date(item)
    a = arrow.get(item)
    print ("m: ")
    print(m)
    print ("a: ")
    print (a)
    print ()

How does this lib handle dates like 10/05/2018. Is it October 5th or May 10th?

You can specify what you are parsing with ".format("DD/MM/YYYY)"

The default should be this MM/DD/YYYY

Btw is this related to the issue?

@aster94 If anything the default should probably be DMY as its used in more countries than MDY.

Hi,
The default is not related to the issue, please read again the first post

2nd and 4th results are examples of .get() returning very hard to detect errors rather than simply failing. This is already reported and needs to be fixed, I also suspect 1st result is lucky rather than reliable. 3rd result is kind of whatever tbh.

Until the .get() problem is fixed I strongly advise you to always pass formats if possible.
