Hello
I must point out that the output of that code is not quite right.
There is a bug that makes some responses not accurate.
Imagine this:
correct = (8,6,6,5)
you guess is (8,8,6,5)
the response should be: * * * #
but it is: * * * -

The problemis in line 36 of the code. Your code check if the next number form "correct" list is in whole "usr_guess" list.
The problem could occur when "correct" list will contain more than one occurrence of some number.
In exaple above program will check:
8 <=> 8 = True >> print ("")
6 <=> 8 >> program goes to elif >> 6 in (8,8,6,5) = True >> print ("-") #the 6 is in the "usr_guess" list, only one time but it is.
6 <=> 6 = True >> print ("")
5 <=> 5 = True >> print ("*")

I do not know best sollution for this problem. I have some idea how to solve this issue, but my sollution require a lot of code and is not simple to explain so it is probably not the best idea ;-)
