Why do you dislike that
i made a liitle typo at the ned, i meant this:
if ( eval( datetime.strptime(date, '%d %m %Y') ) ):
date = datetime.strptime(date, '%d %m %Y').strftime('%Y-%m-%d')
else:
print( "Date wasn't entered properly" )

The datetime function: strptime() DOES check the date for validity. So try
something like:
from datetime import datetime
def get_date():
while True:
try:
date_in = raw_input("Enter date (dd mm ): ")
date_out = datetime.strptime(date_in,"%d %m %Y").strftime("%Y-%m-%d")

Should be:

That parses the date and discards the result.
