Hmmm... it becomes a bit more complicated.
Say, you have this huge string:

>>> HugeString = """ ... lotsa text ..."""

And, your dictionary with search items and replacements:

>>> ReplacementsDict = { "find":"replace", ... }

So, you need to find *any* key, so you can use a regexp:

>>> import re
>>> rxFindKey = re.compile("|".join(ReplacementsDict.keys()), re.S)

To do all the replacements. just do a loop:

>>> match = rxFindKey.search(HugeString)
>>> while match:
...     found = match.group(0)
...     HugeString = HugeString.replace(found, ReplacementsDict[found])
...     match = rxFindKey.search(HugeString)

So, after the loop, you've got all that done.

Good luck!
