Latest python version (Nearly Solved)

[Ivor Hardy]

How do i go about installing the latest python version on mint. Mint 10 has version 2.6.6 installed and i need to upgrade to 3.1 for a course im doing. Also when you see programs on the net and they have versions in Linux,is it ok to download and install or can you run into problems. Thanks in advance.

If you search for python in software manager or synaptic you should find what you're looking for, it looks like there's packages for 2.7 and 3.1.

As far as downloading packages from the web, in theory you can install any .deb package for your architecture, but you should be careful to download only from trusted sources. You can also compile from source, but if you knew how to do that you probably wouldn't be here asking questions

Happy New Year and welcome to Linux Mint!

Installing the latest vanilla version of Python 3.1.3 should not take more than 5 minutes from start to finish as long as you don't need specialized libraries.

Code: Select all

mkdir /home/staging

Code: Select all

cd /home/staging

Code: Select all

wget -c http://www.python.org/ftp/python/3.1.3/Python-3.1.3.tgz

Code: Select all

tar xvzf Python-3.1.3.tgz

Code: Select all

rm Python-3.1.3.tgz (we don't need the archive anymore)

Code: Select all

cd Python-3.1.3/

Code: Select all

./configure

Code: Select all

make

Code: Select all

sudo make install

If you get any errors during the 'configure' segment, which is not very likely, it will produce error messages about missing dependencies. Python is distributed as C source file, so satisfying dependencies is quite straight forward. After you are done, you can delete the directory /home/staging since we only needed it for the build.

For the second question, the only time you might get into hot water is when installing "core" files like glibc on which everything depends. Take the extra 2 minutes and verify the MD5 hash before you install anything. The command is 'md5sum file_name'.

With kind regards,

Sorry to wreck everyones head but i have python installed fine but i cant get the basic programme "hello world" to work. This is it

Code: Select all

#!/usr/bin/python3.1
print ("Hello World")
input ("Press any key to exit")

I save the file as test.py to desktop,in premissions allow it executeable. When i click on it i get the option to run in terminal but then the terminal opens quickly and closes. What the hell am i missing....??? Also when i get the option to run in terminal i also get the option to just "run",this does nothing whats this for..??
