In Python both %s and %d are placeholders for a string and a number respectively.

name = 'Robey’
number = 454
print '%s %d' % (name, number)

%s will return the string and %d will return number, the values are passed using % operator. This % operator formatting is used in C language also.

The reason is that they are using this for formatting the strings. The%s acts a placeholder for a string while %d acts as a placeholder for a number. The associated values of them are then passed in through a tuple using the % operator.

name = 'marcog'
number = 42 
print '%s %d' % (name, number)

The above information will print marcog 42. However, please note that the name is a string (%s) and number is an integer (%d for decimal).

In Python 3 the example would be:
 

print('%s %d' % (name, number))
