python3 idle

Aisthesis · #1 29th May 2010, 04:04 PM

i've gotten my fedora 12 to the point where i can run python3 scripts from command line and can call up python 2.6.2 idle with the command 'idle' from command line.

what command will call up python3 (3.1.2 to be exact) idle?

idle3, believe it or not, which is provided by python3-tools

Oh, those python developers have a sense of humor, guess what happens when you type:

Code:

import antigravity

into idle3?

ok, that helps a bit further, but when i type idle3 at command line i get:

** IDLE can't import Tkinter. Your python may not be configured for Tk.**

I then did a yum search tkinter and installed both of the packages yum found, but still the same message.

so, i guess i still need to somehow get the python3-tools you mention onto the machine.

try

Code:

yum install python3*

That should get everything you need.

Though Hello World in 3.foo is now:

Code:

print("Hello World!")

rather than the syntax used in the 2.foo versions:

Code:

print "Hello World"

Code:

# yum install python3*
Loaded plugins: presto, refresh-packagekit
Setting up Install Process
No package python3* available.
Nothing to do

i did get my command idle3 to work after running

Code:

yum tk-devel.x86_64

but i'm not very confident that i have the complete python3 package installed, since i've more or less just groped around for one thing or the other until the command finally ran. i found that one on python-forums.org as response when someone else had a similar problem.

i guess i can just start writing code until something that's supposed to run doesn't ...

in addition to the syntax different for print ... (2.x) vs. print(...) (3.x), i have the impression that there are a lot of others, although i haven't messed much with 2. i think maybe string.format() works differently judging from some python2 code i've seen.
