Find all index position in list based on partial string inside item in list

mylist = ["aa123", "bb2322", "aa354", "cc332", "ab334", "333aa"]

I need the index position of all items that contain 'aa'. I'm having trouble combining enumerate() with partial string matching. I'm not even sure if I should be using enumerate.

I just need to return the index positions: 0,2,5

Solution

  • You can use enumerate inside a list-comprehension:

    indices = [i for i, s in enumerate(mylist) if 'aa' in s]
