Formatting Output

[victor.herasme@gmail.com]

Hi,

i am building a little script and i want to output a series of columns
more or less like this:

1 5 6
2 2 8
2 9 5

The matter is that i don't know in advance how many columns there will
be. By the way, each column will be actually FLOATs, not INTs. How can
i do this ? Any help welcome. Regards,

Victor

Look at string methods, `join()` for example, and string formatting with
the ``%`` operator.

import sys
float_list = [1.0, 5.0, 6.0, 2.0, 2.0, 8.0, 2.0, 9.0, 5.0]
num_columns = 3
for i,item in enumerate(float _list):
sys.stdout.writ e('%.4f\t' % item)
if not (i+1) % num_columns:
sys.stdout.writ e('\n')

Problem with this approach is it doesn't cater for instances where you
exceed the standard 80 characters for a terminal window.
