Just create a list of these ranges and sort them:

>>> r1=range(780,1015)
>>> r2=range(771,1015)
>>> r3=range(29,215)
>>> r4=range(226,427)
>>> all=[r1,r2,r3,r4]  #here is the list of ranges
>>> all.sort()         #here we sort them
>>> for a in all:
...  print a[0:2],'...'
... 
[29, 30] ...
[226, 227] ...
[771, 772] ...
[780, 781] ...
