The advantage of os.path.join() (if you use it for all joins) is that it is portable, it will use the appropriate path separator for the platform it is running on. These days that is not such a big deal, perhaps, as Mac OSX, Windows and Linux all accept / as a path separator.

[Tutor] Best Python3000 Tutorial for Beginner
Hello all, I just joined this mailing list. I am a beginner to programming in general and would really appreciate a tutorial for Python3000 that at least covers the basics. I have tried reading the manual, but I think it was written for more experienced programmers wishing to switch to python rather than a beginner looking for where to start. Most of the other tutorials I have found were for earlier versions of Python, and because Python 3.0 was released on my birthday, I decided I was meant to learn that release. ;-) Anyway, any help would be appreciated. I will do my best to return the favor. -Ian ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor

I have tried Hello Ian, That is a nice reason to get started with a language. However, you have to remember that Python 3.0 is not a new language at all. It is just a backwards impatible release of the original almighty pyhon, which just tends to increase its strength and clean its design further. I am not at all surprised that you did not find any beginner Python 3.0 tutorial. It might be coming out soon, but the curretly people migrating to Python 3.0 are ones who already know python 2k well. So, for your purposes I would suggest the following. 1) Get Beginner Python tutorial. (See Alan's tutorial in this mailing list and also google for A Byte of Python) 2) Read and understand the language well. Get comfortable upto a point where you can differentiate between string, unicode and bytes. I should warn you that it might take months' time. and now you can read this very beginner friendly introduction to Python 3k. http://www.comp.leeds.ac.uk/nde/papers/teachpy3.html Thanks, Senthil ___ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
[Tutor] Help with elif
Wow, that was a quick response! Thanks all!
I have looked at a couple tutorials and whipped this up. However, attempting
to run it in IDLE results in a syntax error leaving my elif highlighted in
red. What's wrong? I've looked at the code and can't find any syntax errors-
though I've just started.
print("[Temperature Converter, First Edition]")
print("Created on January 17th, 2009 by Ian Egland")
temp1 = int(input("Please enter a temperature: "))
scale = input("Convert to (F)ahrenheit or (C)elcius?")
if scale == "F":
temp2 = (9/5)*temp1+32
print(temp1, "C =", temp2, "F"
elif scale == "C": # Error appears here.
temp2 = (5/9)*(temp1-32)
print(temp1, "F =", temp2, "C"
else:
print("Sorry, you must enter either an F or a C. Case-sensitive. Please
try again."
In regards to learning python, I've found that after I get somewhat-familiar
with a language, I want a programming problem to solve with what I've
learned. While learning Java, http://www.javabat.com has been my best
friend. (That is, as close to a best friend as programming website can be.)
Is there something like this for Java? Is one in the works?

Missing parenthesis in the above line.

Syntax errors often appear on the line *following* the line with the
actual error.

Re: [Tutor] Best Python3000 Tutorial for Beginner
In addition to what was already mentioned, I found "Think Python" useful. It is aimed at both learning programming in general, and it teaches in python specifically. However, it's written for python 2. http://www.greenteapress.com/thinkpython/thinkpython.html On Sat, Jan 17, 2009 at 10:04 PM, Ian Egland wrote: > Hello all, I just joined this mailing list. > > I am a beginner to programming in general and would really appreciate a > tutorial for Python3000 that at least covers the basics.
