python about multiple %s in a string

Question

str = 'I love %s and %s, he loves %s and %s.' 

I want to use this format to display

I love apple and pitch, he loves apple and pitch.

Only add two variable please, but need a way to use it twice in one sentence.

Answer 1

Use a dict:

>>> s = 'I love %(x)s and %(y)s, he loves %(x)s and %(y)s.'
>>> s % {"x" : "apples", "y" : "oranges"}
'I love apples and oranges, he loves apples and oranges.'

Or use the newer format function, which was introduced in 2.6:

>>> s = 'I love {0} and {1}, she loves {0} and {1}'
>>> s.format("apples", "oranges")
'I love apples and oranges, she loves apples and oranges'

Note: Calling a variable str would mask the built-in function str([object]).
