String Formatting
The [http://docs.python.org/lib/typesseq-strings.html section of the manual on String Formatting Operations] is hidden in the section on [http://docs.python.org/lib/typesseq.html Sequence types.]
Direct Variable Reference
A common trick you can use when writing strings is to refer directly to variables.
If you want to refer to global variables, you can replace vars() with globals().

You may find it tricky to print out a feed of numbers (as output from within a loop) on one line, without being separated by a space. An example could be output such as
Processing... [1][2][3][4][5][6] Completed.
The standard print statement automatically inserts newlines. This can be overcome with
for i in range(10): print '['+str(i)+']', # NOTE the trialing comma
but a space will get inserted between successive prints. The way to get around this is using sys.stdout:
import sys for i in range(10): sys.stdout.write('['+str(i)+'[')
which will work properly.
