You persist in top-posting (putting your reply ahead of the sequence of
messages you're quoting).
Regular expressions are an advanced technique. You need to learn how
strings work, how names clash, how functions return values. Learn how
the fundamental types can be manipulated before messing with datetime
module, or re module. As I said in an earlier message:
>>Do you understand what kind of data is returned by raw_input() ? If
so, look at the available

from the mm and from the year.
You've done the same with the more complex and slower re module. You
could have just used the code I practically handed you:
date_string = raw_input("Type Date dd/mm/year: ")
date_list = datestring.split("/")
Then, you have correctly parsed the list into separate string
variables. Easier would have been:
day, month, year = date_list
or just combining the last two lines:
day, month, year = date_string.split("/")
Now you'd like to put them together in a different order, with a
different separator. The re module doesn't do that, but again, you
don't need it. Look up str.join(), which is pretty much the inverse of
split, or simply look up how to concatenate strings with the "+" operator.
Now, consider the calling and return of that function. What are you
using the formal parameter "date" for? Why is it even there? And what
value are you intending to return?
Try writing one complete script, complete with a single definition, and
a single call to that definition, perhaps printing the result calling
that definition. Master chapters 1-3 before jumping to chapter 12.
