Try this:
f=open("xxx.dat","w")
f.write("fff")
d={'one':1, 2:'two'}
f.write(str(d))
f.close()

[Tutor] Open source projects build using Python
Dear All, I've been working on Python for a while but haven't got any chance to work on any projects yet. I've spent most of my time reading codes. (I know this is bad when you want to actually learn a programming language) It would be a better idea that I can start to join an open source projects that is built with Python instead of starting up a new project. (I have no good ideas at this moment anyways) I know there are lots of projects which I can work on, but just wanted to hear some recommendations what are the ones good for a long time Python "reader"? -- Regards, YeeYaa (Simon Yan) http://simonyan.fedorapeople.org/ ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor

If you simply want to stop after an exception was caught, you can insert
"break" after each print line. Like below:
>>> while True:
try:
number = raw_input("enter number - ")
print number * number
except ValueError:
print "invalid number"
break
except:
print "unspecified exception"
break
else:
print "other conditions"
break

I would recommend start off from a simple text editor that has basic syntax
highlighting features. There are a number of options out there.
TextMate is a good choice, a little pricy.
VIM, if you are a terminal guy
Even Python IDLE is a good choice you wanted to edit just a few simple .py
files.
I would suggest give it a look in the Mac App Store and you will find a few
other good ones too.

I don't think there is a file type of Python that you can create from Xcode.
Just curious, why would you want to use XCode as a Python editor?

It appears that the issue is from this:
elif(y[len(y)-1] != vowels):
This condition will be true because you are comparing a string with a list.
Thus causing passwrod() returning False.
