Hi.
My problem is to replace all occurrences of a sublist with a new element.
Example:
Given ['a','c','a','c','c','g','a','c'] I want to replace all
occurrences of ['a','c'] by 6 (result [6,6,'c','g',6]).
If I do this with string ('acaccgac') I have the advantage of all the
'find' functions, but perfomance is bad and some extra care must be
taken if one element consist of more then one character (case of 11 for
example)
So I really would like to work with lists straightforward, but I could
not found anything to search a sublist inside a list.
Any propositions for a simple solution?
For a mutable homogenous array, consider the array module.
Any algorithm that applies to a sequence of chars can be adjusted to
other sequences. For the above case, remember than you can easily
filter None out of a sequence. IE, replace 'a','c' with 6, None and
then filter when done.
