With regular expressions:
>>> import re
>>> replacements = iter(["one", "two", "three"])
>>> re.compile("replaceme").sub(lambda m: next(replacements), "foo replaceme
bar replaceme baz replaceme bang")
'foo one bar two baz three bang'
With string methods:
>>> replacements = iter(["", "one", "two", "three"])
>>> "".join(a + b for a, b in zip(replacements, "foo replaceme bar replaceme
baz replaceme bang".split("replaceme")))
'foo one bar two baz three bang'
