Yes, to highlight this last comment, the code as written is building one
string to pass to print, in other words it is similar to doing:
x = chunk1 + chunk2 + chunk3
of course there's no assignment to 'x' taking place, I just use that to
illustrate that print is called with one argument.
and Bob is suggesting you can also let print do the combining:
print(chunk1, chunk2, chunk3)
it which case it applies a little formatting work for you (inserting the
space). There will be lots more options to string formatting for print.
Meanwhile, it is worth pointing out that while: (as with other python
loops) can take an else: clause, which is executed if the loop runs to
completion and was not exited via break. That means you could ALSO
write (this is pseudo-code for brevity):
while guessesTaken < 6:
if guess_value == number
# if we got here it's because a guess was correct
Using this is no more or less correct than not using it, just pointing
it out for your learning about Python loops. Apparently some people
think while/else, for/else and so on are useless, or vile, or whatever.
But they're certainly a part of the language.
