How to find out for yourself:
>>> def fun(self):
"""doc comment
comment line 2
"""
x = 1
y = 2
"""does this triple quoted string used as a comment
cause something to happen at runtime beyond
just skipping over it? Such as allocation of memory for a string
or worse yet garbage collection? or not?
"""
z = x + y
>>> import dis
>>> dis.dis(fun)
6 0 LOAD_CONST 1 (1)
3 STORE_FAST 2 (x)
7 6 LOAD_CONST 2 (2)
9 STORE_FAST 1 (y)
14 12 LOAD_FAST 2 (x)
15 LOAD_FAST 1 (y)
18 BINARY_ADD
19 STORE_FAST 3 (z)
22 LOAD_CONST 3 (None)
25 RETURN_VALUE
>>>
Further inspection shows that it hasn't even saved that second string as a
constant:
>>> print fun.func_code.co_consts
('doc comment\n comment line 2\n ', 1, 2, None)
