If the programs that you type in run as soon as you are typing them in, you need to edit a file instead of typing them in interactive mode. (Hint: interactive mode is the mode with the >>> prompt in front of it.)
My question is not answered here.
Ask on the talk page. Please post source code if at all relevant (even, (or maybe especially) if it doesn't work). Helpful things to include are what you were trying to do, what happened, what you expected to happen, error messages, version of Python, Operating System, and whether or not your cat was stepping on the keyboard. (The cat in my house has a fondness for space bars and control keys.)
How do I make an executable from a Python program?
Short answer: Python is an interpreted language so that is impossible. Long answer is that something similar to an executable can be created by taking the Python interpreter and the file and joining them together and distributing that. For more on that problem see http://www.python.org/cgi-bin/faqw.py?req=all#4.28. A project that does make executable python files is py2exe - see http://www.py2exe.org.
I need help with the exercises
Hint, the password program requires two variables, one to keep track of the number of times the password was typed in, and another to keep track of the last password typed in. Also you can download solutions from http://www.honors.montana.edu/~jjc/easytut/
