Formatting a tuple of floats

How can I format a tuple of float to .3f?

In [1]: pi=3.14159265359

In [2]: print "{:.3f}".format(pi)
3.142

In [3]: e=2.71828182

In [4]: z=(pi,e)

In [5]: print z
(3.14159265359, 2.71828182)

You could use 

print '{:.3f} {:.3f}'.format(*z)

You format each float value in the tuple:

print ' '.join(format(f, '.3f') for f in z)

I used the format() function here to achieve the same formatting for individual floating point values.

Output:

>>> pi=3.14159265359
>>> e=2.71828182
>>> z=(pi,e)
>>> print ' '.join(format(f, '.3f') for f in z)
3.142 2.718

Adjust the join string as needed.
