[Tutor] float question

[Pujo Aji]

Th format %x1.x2f
where x1 is the total space and x2  is decimal digit place.

If your data is longer than the specified x1 and x2.
the data rules.

Look at 3.14 takes 4 places total

# 4 places rules
>>> '%3.2f' % 3.14
'3.14'

# perfect
>>> '%4.2f' % 3.14
'3.14'

# try this
>>> '%5.2f' % 3.14
' 3.14'

Cheers,
pujo
