Hello. I am currently working with Python version 3.1.1 . I am working out
of the book called Python Programming for the Absolute Beginner Third
Edition which teaches version 3.1.1 . I wrote the following blackjack
program that is on page 275 and I imported the modules that you see below.
First the cards module which is on page 271 and then the games module which
is on page 268. I tried typing everything in exactly the way it is in the
book but when I run the blackjack program that you see below it will first
ask me how many players just like it should, then I tell it how many
players, then it will ask me the names of each player just like it should,
then I tell it the name of each player and after I do that and press enter
I get the following error message.
Traceback (most recent call last):
File "C:\Python31\blackjack.py", line 184, in<module>
main()
File "C:\Python31\blackjack.py", line 181, in main
game.play()
File "C:\Python31\blackjack.py", line 132, in play
print(player)
File "C:\Python31\blackjack.py", line 34, in __str__
rep = self.name + "\t" + super(BJ_Hand, self).__str__()
TypeError: can only concatenate list (not "str") to list
Did you omit the __init__() method on some of these classes? For
example, I don't see one for BJ_Player, and yet instances are created
with a name argument.
Anyway, let me point you to a standard debugging technique which should
be introduced by page 10 of any such book:
You have an error message which is complaining about a specific line,
and the error message is complaining about the types of the objects in
the expression on that line., So add some print()s, to show type and
value (usually repr() is good enough) for the items in the statement.
Judging from the wording, self.name is a list, rather than a string as
expected. Given that, work backwards to see how it got its value.
