Have you heard of the high elves, I mean, regex? :>

Answer 2

You can use the string method 'find'. It gives you the index of the found string.

You can tell it where to start looking.

Then write a little loop, find all the indexes and put them in a list.

Nice little practice task.

Since the RegEx solution is already given, and it's nicely short anyway, let me add the more lengthy builtin style version for reference:

occurrences = []
word = 'abracadabra'
i = 0
while True:
f = word.find('abr', i)
if f==-1:
break
occurrences.append(f)
i = f+1
print(occurrences)

Answer 3

I don’t care what form the output is in as long as it is usable
