You can use string formatting to create the string any way tou want:

print "%d%d" % a,b

will print 01

Or you can use string conversion and catenastion:

print str(a)+str(b)

to get a similar result.

Incidentally your loop would be clearer if you omited the tuple 
assignment:

while b < 10:
     print a, b,
     b +=  1

And if you only use 'a' to zero pad the number you can do that with
string formatting too:

print "%02d" % b


Personally I'd go for string formatting because of its much more
powerful and flexible options.
