printing - How do I print a list of doubles nicely in python? -


so far, i've got:

x=[0.0, 1.2135854798749774, 1.0069824713281044, 0.5141246736157659, -0.3396344921640888, -0.33926090064512615, 0.4877599543804152, 0.0]  print ' '.join(["%.2f" % s s in x])

which produces:

0.00 1.21 1.01 0.51 -0.34 -0.34 0.49 0.00

the problem being -0.34 1 character longer 0.51, produces ragged left edges when printing several lists.

any better ideas?

i'd like:

0.00 1.21 1.01 0.51 -0.34 -0.34 0.49 0.00 0.00 1.21 1.01 0.51 0.34 0.34 0.49 0.00 0.00 1.21 -1.01 -0.51 -0.34 -0.34 -0.49 0.00

to turn into:

0.00 1.21  1.01  0.51 -0.34 -0.34  0.49 0.00 0.00 1.21  1.01  0.51  0.34  0.34  0.49 0.00 0.00 1.21 -1.01 -0.51 -0.34 -0.34 -0.49 0.00

and nicer if there built in or standard library way of doing this, since print ' '.join(["%.2f" % s s in x]) quite lot type.

simply adjust padding positive , negative numbers accordingly:

''.join(["  %.2f" % s if s >= 0 else " %.2f" % s s in x]).lstrip()
