The simple conversion, with only a conversion type, is really easy to use:
print 'Price of eggs: $%d' % 42
print 'Hexadecimal price of eggs: %x' % 42
print 'Hexadecimal price of eggs: 2a'
print 'Pi: %f...' % 3.1415926
print 'Very inexact estimate of pi: %i' % 3.1415926
print 'Using str: %s' % 42L
print 'Using repr: %r' % 42L
# ww w . ja v a2 s .c o m
print "%x" % 108
print "%X" % 108
print "%o %x %X" % (64, 64, 255)
print '%.2f'%(1/3.0) # results in: '0.33'
print '%s'%(1/3.0) # results in: '0.333333333333'
The code above generates the following result.
