[Tutor] python3.4m

[Alex Kleider]

A listing of /usr/bin/python* on my Ubuntu 14.04 LTS machine yields the 
following:
alex at t61p:~$ ls -l /usr/bin/python*
lrwxrwxrwx 1 root root       9 Aug 23  2014 /usr/bin/python -> python2.7
lrwxrwxrwx 1 root root       9 Aug 23  2014 /usr/bin/python2 -> 
python2.7
-rwxr-xr-x 1 root root 3176896 Mar 22  2014 /usr/bin/python2.7
lrwxrwxrwx 1 root root       9 Aug 23  2014 /usr/bin/python3 -> 
python3.4
-rwxr-xr-x 1 root root 3802224 Apr 11  2014 /usr/bin/python3.4
-rwxr-xr-x 1 root root 3802224 Apr 11  2014 /usr/bin/python3.4m
lrwxrwxrwx 1 root root      10 Aug 23  2014 /usr/bin/python3m -> 
python3.4m

What is python3.4m?
When might one want it instead of python3.4 without the 'm'?

thanks,
Alex
