Python: % Operator in Print() Statement

I just came across this Python code, my question is about the syntax in the print statement:
class Point(object):
"""blub"""
#class variables and methods
blank = Point
blank.x = 3.0
blank.y = 4.0
print('(%g,%g)' % (blank.x,blank.y))
This print statement simply prints (3.0, 4.0), i.e. the values in blank.x and blank.y.
I don't understand the % operator in front of the (blank.x, blank.y) in the last line. What does it do and where can I find it in the documentation?
Googling this, I always end up with the modulus operator.

Intro
The % operator in python for strings is used for something called string substitution.
String and Unicode objects have one unique built-in operation: the % operator (modulo).
This is also known as the string formatting or interpolation operator.
Given format % values (where format is a string or Unicode object), % conversion specifications in format are replaced with zero or more elements of values. The effect is similar to the using sprintf() in the C language.
If format is a Unicode object, or if any of the objects being converted using the %s conversion are Unicode objects, the result will also be a Unicode object.
