%s will return the string and %d will return number(intger), 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.

example.
name = 'guru'
number = 99
print( '%s %d' % (name, number))
The above information will print =guru99.

%s(string)=guru
%d(integer/number)=99

you really should find newer learning materials. These are mainly for legacy codes that used older python versions. Good to know, but not good to still include in your code.
