subprocess.py. Bad idea ;)

Delete or rename your subprocess.py, and the one in the standard library

Re: [Tutor] Desperately need help to uninstall python from my mac

[Ries Rommens]

Hello Christian,

You don't have to uninstall python before upgrading Tcl/Tk.

Steps to follow:

Close Idle, if activated.

Browse to

http://www.activestate.com/activetcl/downloads

and find your Mac Disk Image (DMG), it's about halfway the webpage.
I have used version 8.5.18.0.
Download and install the DMG in the Apple way. (Right click on the icon, 
and click [Open], instead of doubleclick).

Activate Idle after installing Tcl/Tk, and the warning has gone.

Hope it helps,

Ries

Hello,
As the subject line indicates, I really need help uninstalling python on my

Uninstalling python from a mac seems to be an absurdly overlooked topic. The 
one resource i have found addressing the issue, a stack overflow thread, 
doesn't give me the amount of direction i need to successfully uninstall.

The reason i (think i) need to uninstall python is that when i open IDLE i get this 
warning: "WARNING: The version of Tcl/Tk (8.5.9) in use may be unstable.Visit 
http://www.python.org/download/mac/tcltk/ for current information.".

I've heard i need to install a system appropriate tcl/tk (which i believe i 
have done) before reinstalling python, but seeing as i cannot uninstall python 
I do not see any way to resolve this issue. Python.org doesn't seem to have any 
information that addresses this problem, so I have come here in hopes of some 
guidance.

Thanks,-Christian

You almost certainly don;t want to to do that! Your Mac will stop
working properly, it uses Python. That's why its installed by
default on Macs.

OK, So you have IDLE which is not ion a Mac by default so maybe you
installed an extra version of Python and you want to uninstall that?
Thats a very different thing that uninstalling Python entirely.

But the warning only says the version of Tcl/Tk *may* be unstable.
Does IDLE in fact work? If it doesn't can you replace the Tcl/Tk
libraries rather than Python?

> Visit http://www.python.org/download/mac/tcltk/ for current information.". 

Did you read that page?
Did you do what it suggested and install an ActiveState version
of Tcl/Tk for MAC?

Which versions of MacOS and Python are you using?

> I've heard i need to install a system appropriate tcl/tk (which i

What makes you believe it? Which version did you install?
Where did you get it?

> to resolve this issue.

Once we understand which version of Python you installed we
can start to consider whether/how you need to uninstall it.
What you should not do is try to uninstall the system version
of Python used by MacOS.

Did you read this page:

https://docs.python.org/3/using/mac.html

It doesn't explicitly tell you how to uninstall it, but it
does tell you what is installed, and where...

I would echo those saying "make something" - for me the thing that 
really moved me forward was doing a data project, make the sqlite 
database, manipulate it, make a Flask site to access it, etc.  Lots of 
resources on the web to guide you to do such things.


Alternatively try some of the many coding challenge sites.  My daughter 
is currently loving CodeAbbey.  A trick to CodeAbbey - there are lots of 
tools in Python that make the challenges vanishingly easy (at least the 
early ones) but you will likely learn more if you force yourself to 
write those programs without Python's "batteries included" tools.

Other have recommended starting a project and that's always the best way.

But if you are really stuck for ideas try the Python Challenge.
It's a game where you solve puzzles by writing Python code and
each solution gives you the url for the next puzzle. It's a great
way to learn about the standard library.

Re: [Tutor] Practice Exercises for Beginner ?

[Alex Hall]

Make something. :) I know it's pretty open-ended, but just think of an 
application you want to make, and try to make it in Python. Stick to command 
line at first, but then try WX or another GUI library. The more times you get 
stuck, the more you learn and the more you'll know for next time. Make 
Battleship, make a website in Flask or Django, make a unit converter, make 
chess, make an audio player... Find a functionality you know, and try to make 
Python do that function. That's really the best advice I've ever gotten for 
learning any new language.
