Still not tested enough to ensure that it's bug free, but more
concise. Here's one

Kent Johnson had the right approach, with regular expressions.
For a bit of optimization, use non-greedy groups. Tha
Just another solution, pretty and effective:
def fct(a, b):
idx = -1
for c in a:
idx = b.find(c, idx+1)
if idx == -1:
return False
return True

thanx everyone, is what i need.
As Claudio argues, it's a standard problem of dna sequences
comparation.
the next step of my job is to make limits of lenght of interposed
sequences (if someone can help me in this way i'll apreciate a lot)
thanx everyone.

If I understand it right, it should be something
like this:
def blnFindCharSequenceAevenIfSpreadOverEntireStringB(strA, strB):
intNoOfCharsFound = 0
intPtrToBeginOfSubsectionOfB = 0
intLenA

Hello Giorgi,
I suggest to google for "python boyer moore" to get a fast
implementation of a string search algorithm in Python (the Boyer-Moore
algorithm).
One promising hit seems to be:
