[Tutor] Sorting a dictionary

[Johan Geldenhuys]

Hi all,
In my new project I needed a dictionary with TCP/UDP port numbers as 
keys and the service for that key as the value.
I got the info from the services file in Linux and compiled a dictionary 
as I needed.

The only thing that I want to do is to sort the dictionary from the 
smallest key number to the largest key number.

Example:

I have:
ser_port = {'4401': 'ds-srvr', \
 '5427': 'sco-peer-tta', \
 '4446': 'n1-fwp', \
 '3734': 'synel-data', \
 '4447': 'n1-rmgmt', \
 '5745': 'fcopy-server', \
 '5990': 'wbem-exp-https', \
 '4026': 'as-debug', \
 '3724': 'battlenet'}

I want:
ser_port = { '3724': 'battlenet', \
'3734': 'synel-data', \
'4026': 'as-debug', \
'4401': 'ds-srvr', \
'4446': 'n1-fwp', \
'4447': 'n1-rmgmt', \
'5427': 'sco-peer-tta', \
'5745': 'fcopy-server', \
'5990': 'wbem-exp-https'}

My dictionary comsists of a few thousand entries and it will not be fun 
to do this manually. How do I sort the dictionary to read better/easier?

TIA,
BTW: If anybody wants this to use, please ask.
