How to convert a string like "28 JUL 1795" to a date with the format of"%B %d, %Y"?

Question

I used following line to transfer my date string but it gave me an error.

print datetime.datetime.strptime(arg, '%d %b %Y').date().strftime("%B %d, %Y")

ValueError: time data '28 JUL 1795' does not match format '%B %d %Y'

For this example I get a different error: `ValueError: year=1795 is before 1900; the datetime strftime() methods require year >= 1900` — user4815162342, Mar 03 '14 at 19:23
[Works for me](http://ideone.com/aJ3bQI). Please provide a short complete program that demonstrates the error. — Robᵩ, Mar 03 '14 at 19:24
@roippi And the traceback does not match the code. If any it should be `...does not match format '%d %b %Y'`. — Hyperboreus, Mar 03 '14 at 19:27
@user4815162342 The error you posted cannot possible come from the piece of code you posted. How can there be a problem with `'%B %d %Y'` if it doesn't appear anywhere in your code. — Hyperboreus, Mar 03 '14 at 19:29
In my original question the date str was "28 JUL 1795". Somebody changed it. the program works perfectly for dates after 1900. I'm looking for a solution (a function) that works before 1900 too. — user3324502, Mar 04 '14 at 15:19

This behaviour is not reproduceable. The following works as intended:

>>> datetime.datetime.strptime('28 JUL 1995', '%d %b %Y').date().strftime('%B %d, %Y')
'July 28, 1995'

Maybe your input string is not what you expect it to be.

That's exactly my program. I'm trying to find a way to do it for before 1900. – user3324502 Mar 04 '14 at 15:24
