% character marks the beginning of the conversion specifier. 

Conversion flags, minimum field width, . (dot) followed by the precision.



Conversion flags may be -, indicating left alignment; 

                        +, indicating that a sign 

                      " ", indicating that a space should precede positive numbers; 

                        0, indicating that the conversion should be zero-padded. 



 





print 'Price of eggs: $%d' % 42 



print 'Hexadecimal price of eggs: %x' % 42 

from math import pi 

print 'Pi: %f...' % pi 



print 'Very inexact estimate of pi: %i' % pi 



print 'Using str: %s' % 42L 



print 'Using repr: %r' % 42L
