Python: Nicest way to pad zeroes to string

>>> n = '4'
>>> print n.zfill(3)
>>> '004'

>>> n = 4
>>> print '%03d' % n
>>> '004'

print "%05d" % number

print("{0:05d}".format(number)) # or
print(format(number, "05d"))

>>> t = 'test'
>>> t.rjust(10, '0')
>>> '000000test'

width = 10
x = 5
print "%0*d" % (width, x)
> 0000000005

>>> n = 3
>>> str(n).zfill(5)
'00003'
>>> n = '3'
>>> str(n).zfill(5)
'00003'
>>> n = '3.0'
>>> str(n).zfill(5)
'003.0'

>>> a = 6340
>>> b = 90210
>>> print '%05d' % a
06340
>>> print '%05d' % b
90210
