Need help with python!!

BongFish · 08-23-2003, 11:13 AM

Hello people,
I've been learning Python as my first language but can't find two things in any of the tutorials:

1. How can you create GUI's for your programs? I want to be able to make programs which appear in an X window, for instance I'd like to make a little slide show program or something.

2. Is there an equivalent of a GOTO command like in DOS batch files? It would make life much easier in some situations, the only semi-equivalent seems to be the def function

Thanks a great deal, links to tutorials about the above things would be much appreciated.

1. most toolkits have python bindings, e.g. pygtk for Gtk... go google

2. hahaha... don't use goto's... they are obscenely bad practise in the main...

1) Take a look at gtk
http://www.gtk.org

2)A good quick and dirty tutorial is here:
http://www.hetland.org/python/instant-hacking.php

Code:

    def hello(who):
        print "Hello,", who

    hello("world")
    # Prints out "Hello, world"

Okay, GTK. Pardon my ignorance but GTK uses things called widgets doesn't it??

I'll take a look.

Why are goto's considered bad programing?

Aha! That is where the EVIL and WRONG tutorial is. Thanks for the link so I can email the guy and tell him how EVIL and WRONG he is for using input() in a tutorial for newbies.

Lesson: quick and dirty, bad.

Yes .... and? Every toolkit uses widgets of some sort. That's kind of what defines them as toolkits and not just drawing libs.

If you really want to know, read Dijkstra's article. But the short and sweet version is this: it makes programs more complex than they need to be and it offers no advantages.

LOL, I had no idea that all 'toolkits' used widgets or what they were.

I've downloaded pygtk, had a play around with it and looked through the example scripts.

Strike:- I guess I won't be using that guide then, it doesn't look very indepth anyway. I'm using the Python Tutorial for non-programmers from the python website at the moment, it's good so far.

Some good tutorials for teaching the basics are at the bottom of the page under the ones "For Younger" somethings, the Livewires tutorials. Sure, you may not be a kid, but they work.

I'm 16 so I'll only feel slightly patronized reading thoes.

Cheers.

Odd_Bloke · 08-25-2003, 10:05 AM

I'm 15 and I only feel patronised because I've done them all before and am now programming my own stuff (and helping write new sheets, my name is on Snake) using the libraries supplied.
