I run linux mint

I downloaded python 3.3.1 and ran:

make test
sudo make altinstall

However python3.3 did not show up in /usr/bin, but there is a python3.3 folder in /usr/local/lib alongside python2.7 and python3.2 folders.

There is another python3.3 folder in /usr/lib, but it only contains one file which is: /usr/lib/python3.3/lib-dynload/

How can I install it so that I can have /usr/bin/python3.3?

can you do ls -ltr /usr/local/bin/python3.3 – thefourtheye Apr 30 '13 at 15:28
It returns the following: -rwxr-xr-x 2 root root 10305765 Apr 30 17:33 /usr/local/bin/python3.3 – urbanslug Apr 30 '13 at 15:34

The Python executable has been installed in /usr/local/bin. Everything belonging to Python 3.3 has been installed under /usr/local.

That's because /usr/local is the default prefix for locally installed packages. If you would like to install it into /usr, just pass a different prefix to the configure script:

./configure --prefix=/usr

However, I must say that Python 3.3 is in the Ubuntu archives since Quantal. You should prefer using the official Ubuntu package, unless you need to customize things. To install it, use the following commands:

sudo apt-get update
sudo apt-get install python3.3

Lastly, whether you want to use the official package or not, it must be noted that /usr/local/bin is in the default PATH, so there should be no need to install the executable into /usr/bin. I would discourage doing so, as it may be a source of conflicts in future upgrades.

what exactly does this mean? "...Python 3.3 is in the Ubuntu archives..." I want python 3.3 so that I can use pygame. – urbanslug Apr 30 '13 at 15:37
@urbanslug: I have added the information that explain how to install Python from the official archives. – Andrea Corbellini Apr 30 '13 at 15:43
@urbanslug: I noticed that pygame is packaged for Ubuntu too, you do not need to install it manually. – Andrea Corbellini Apr 30 '13 at 15:45

You can follow @Andrea's answer. Or

sudo ln -s /usr/bin/python3.3 /usr/local/bin/python3.3

Would create a symbolic link
