Use string.find() for multiple cases

Question

For .find() how would you find the cases in multiple places?

For example:

string = 'banana'

string.find('na')

I want it to return [3, 5] by creating a blank list and appending it. How would I go about this?

Answer 1

>>> import re
>>> [m.start()+1 for m in re.finditer('na', 'banana')]
[3, 5]

Answer 2

Based on this answer, you can do:

>>> import re
>>> [m.start() for m in re.finditer('na', 'banana')]
[2, 4]

In most programming languages, you start counts with 0, not 1, that's why the "na"s start at 2 and 4, not 3 and 5.
