If ''.join(iterable_of_strings) executes, the result is a string and str =

would not be needed. If you try
"".join(tulemus2)
by itself, you will see the same error.

Since tulemus2 is an iterable_of_bytes, you must join with bytes b'' and =

call str on the result. So just add the b prefix.

What Roy tried to say to you earlier is that when you get an error in a=20
expression, and you do not understand *exactly* where in the expression=20
the error is, pull the expression apart and test the pieces=20
individually. This sometimes includes splitting

print(expression)  # into

s=3Dexpression
print(s)

--=20
