In python if you have 3 * 'bob' the result will be bobbobbob So you need to turn the number_child into a number like so: int(number_child) You will need to do the same thing for the number of adults. That will get you started, but if your user types in something that isn't a number, your program will fail. See if you can get it to work for good data and then come back with what happens when you type in other than integers. Also, when your program fails, it prints out what is called a traceback.

I hope to hear from someone; thank you very much for helping me. I am very appreciative! Firstly, what version of the book are you using? (Or more specifically, what version of Python is the book using?) You're just setting yourself up for trouble if your book is using a substantially different version of Python than you are. (The first version of the book, for example, came out in 2003 and uses Python 2.2...) The second edition came out around 2006 so probably also uses Python 2.x so even if you're using that, I'd suggest you perhaps consider uninstalling Python 3 and (for now at least) installing something closer to what the book is using. (Sorry if this causes you trouble, but IMHO it's probably better for you to not introduce more unnecessary variables that make your learning more complicated that it needs to be and using Python 3.x when your book is 2.x will make things more complicated than it needs to be.) Secondly, have you actually read the first 3 chapters? I ask, because by your question it appears you may not have, or may not have properly absorbed the content. For example, in the first chapter of the book (at the least, the first version), your question is partially answered. I quote: *Waiting for the user* The last line of the program: raw_input(\n\nPress the Enter key to exit.) displays the prompt Press the Enter key to exit. and waits for the user to press the Enter key. Once the user presses the key, the program ends. This is a nice trick to keep a console window open until the user is done with an application. Similarly, there's a section entitled Getting user input in chapter 2. So, to echo Ramit, are you having trouble understanding how the author does it in Chapter 1 2? If not, what are you stuck on?

[Tutor] how I overcame the problem I cannot run Python programs
I realized that my computer was running the programs. The black box was flashing off and disappearing immediately, so that I never saw the programs. Also, I am using Notepad++, in addition to IDLE. I am now able to see my programs and provide user input, when I use Notepad++. Also, I still have not fully overcome, I am slowly on my way to success. I am working vigorously on Python, but only 10% of my time is learning Python. The rest of my time is learning everything related to Python, to get my programs to work.

I am very appreciative for the many valuable individuals who graciously take
their precious time to help others in need. Special thanks to:
Brian van den Broek,Bob Gailer,and Hugo Arts.
I followed all the instructions of Hugo, Bob, and Brian. This is specifically
what I am now doing so that I can see the programs that I run, and also be able
to provide user input:
try:import os# my programfinally:input ('\n\t\t\tPress the enter
key to continue.')os.system ('pause')

It's more conventional to put the import at the very top, before the
try: line.
But otherwise what you have should be fine. There are other ways of
doing it and eventually you may write programs that don't require the
press enter... line and you can then miss out all of the code above. But
for learning that's fine.
Or just run your programs inside IDLE or, as someone else suggested,
Eclipse and PyDev (although personally that seems like overkill!)

True, but in this case, if there is an import error, the message will flash by
without being read. Wrapping the *entire* program, imports and all, ensures
that the program will pause regardless of what happens.

No, it's not crap, it's one of the most powerful and extensible development tools available and used by thousands (millions?) of professional programmers worldwide. But... I tried it 10 years ago and gave up because it was so slow. It's written in Java and 10 years ago few PCs had the horsepower to run Java well, and the Java compilers/VM were less efficient too. I tried it a couple of months ago for two weeks and again gave up for the same reasons. Unless you are still using the same 10 year old PC it shouldn't have been that bad! I certainly don't find it any slower than most large apps these days. Why not stick with pythonwin, it's perfectly adequate for my needs? For a beginner to python I tend to agree with you. Not because Eclipse is slow but because it's way over powered for the simple programs beginners write. If you want to develop a large application with dozens/hundreds of files and packages on Windows then Eclipse (or Netbeans etc) is a useful tool to have. And if you need to develop code in many different languages again, Eclipse will provide consistency. And if you need to build design models in UML you get a choice of top-end tools. But, for single-file programs Pythonwin and even IDLE are perfectly adequate. -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
