Answer #1:

The ‘%’ symbol has a lot of different meanings.

In this case, it’s refererring to string formatting:

Basically, it allows you to substitute a placeholder in the string with a new value.

>>> 'a%s' %('b')   # adding string
'ab'
>>> 'a%i' %(1)     # adding integer
'a1'
>>> 'a%d' %(1)     # adding integer (another form) 
'a1'

However, for integers, % has an entirely different meaning and can return a remainder from integer division (5%2 == 1).
