My point is that the code you posted can't even run, let alone do a good
job. The indentation is all messed up and will yield errors.
The 2nd code works, but only outputs all the higher and lower outputs
after the 10 guesses.
How are you running the code?
Are you using the interactive prompt to type it in? Are you running it in
an ide like idle?
If you put it in a file and run it from the OS command line the second
version should more or less work.

Yes and your code should do that if you put it in a file. If you try
typing it at the python prompt you may well get the result you describe.

The second block should kind of work. From your description I'd guess
you have an indentation error such that most of the code that should
be inside the loop is being bypassed. Are you sure the code you sent
us exactly what you are running?

Re: [Tutor] calling printf() in a C language DLL using ctypes.CDLL
A long time ago when I was working with Python and DLLs I slapped together a basic and ugly example. You can find it here: https://github.com/James-Chapman/python-code-snippets/ tree/master/DLL_C_funcs_w_callbacks The whole thing should load into Visual Studio. I can't guarantee that it works in its current state though. It was created mainly as a reminder to myself. -- James ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
Re: [Tutor] calling printf() in a C language DLL using ctypes.CDLL
Hmmm, I guess then it's time for me to ask this question: Is how I do this
the way you do it?
I have been inserting lines like this: print("The program got here!")
all over my python code whenever I want to know where the program went.
If you want to know where your program went when something went wrong or
when it triggers a if condition, how do you do it?
Thanks!

Re: [Tutor] guess my number game
Hi there,
Yes, the first code does a good job by asking them to go higher or lower
after each guess, in the pop up window.
The 2nd code works, but only outputs all the higher and lower outputs after
the 10 guesses. Everyone in the class has the same result basically. When
I searched on various sites, they also work this way. I can allow them to
be finished at this point, but we just wanted the game to tell the user if
he should go lower or higher after every guess.
Does this make sense?
Thank you,
Kerri

Re: [Tutor] guess my number game
Perhaps the indentation was changed when I copy and pasted it, but also
we've only been using codeskulptor to run our answers. That code did work
on ours, so that is weird. But yes there are a lot of errors.
We just type it into code skulptor and press play. A box pops up for any
user input. The display is covered by the box, so you can't see any
results as you are guessing.
We will still be trying to work on this code. We will try the file option
you suggested. We don't have access to the OS at school...
Thank you,

[Tutor] Choice of tools
Hi all, I have a question about how to choose a proper IDE for C/C++
I have been using visual studio ever since my C++ 101 days, but now I
realized there is a problem: feature lock-in!
As an aside, I can't get "Error squiggles" to show up in my .c project in
visual studio 2017, where as in my .cpp project it promptly notifies me
of anything it doesn't like, such as printff("Hello world! \n );
Anyone know how to make it work for .c?
So I have been happily letting MS VS 2017 community do my thinking
for me, so to speak, when it comes to error checking. Now I found out
I can't do any work since there isn't that Error squiggles feature for me,
I have to hunt down my next IDE!
Well, Notepad++ has this really cool "VIM dark blue" theme that is
gorgeous! However, I am a lose for choosing my next editor/IDE...
1) is it ok to get used to a feature that only some products feature
2) is there anything else that has Error squiggles?
3) recommend a C/C++ editor?
Thanks all...
