Method one: accumulate your numbers into a single string, then print it in
one go.
>>> L = []
>>> for x in range(3):
... L.append(str(x))
...
>>> print ''.join(L)
012
>>>
Or even:
>>> print ''.join(map(str, range(3)))
012
>>>
Or use a list comprehension:
>>> print ''.join([str(x) for x in range(3)])
012
>>>
Method two: don't use the print statement, but write directly to standard
output.
>>> import sys
>>> for x in range(3):
... sys.stdout.write(str(x))
...
012>>>
But notice how this does not write a newline when you are done -- you will
have to remember to do it yourself with sys.stdout.write('\n').
Also, print will work with any object, but sys.stdout.write will only work
with strings:
>>> print 6
6
>>> sys.stdout.write(6)
