Removing a 'range' of characters at specific indexes in string

I have looked over similar questions, but I still have trouble figuring this one out.

I have two Lists of strings, one of which consists of characters like 'abcdefg' and another one consisting of strings which consist of white spaces and a special character. The special character indicates where I should remove characters from my 'abcdefg' string. The special character's position in the list would be the same position I would need to remove a character from the first list. I also need to remove the adjacent characters.

EDIT: I want to remove a character (and the adjacent characters) at the same position the '*' char is located in airstrikes, but in reinforces. Does this make sense?

reinforces = ["abcdefg", "hijklmn"]

airstrikes = ["   *   "]

battlefield = reinforces[0]

bomb_range = 

count = 0



if range(len(airstrikes)) != 0:

    for airstrike in airstrikes:

        for char in airstrike:

            print(count)

            count = count + 1

            if (char == '*'):

                bomb_range.append(count-1)

                bomb_range.append(count)

                bomb_range.append(count+1)

                break





#Trying to hardcode it initially just to get it to work. Some kind of looping is needed though.

battlefield = battlefield[:bomb_range[0]] + battlefield[bomb_range[1]:]

battlefield = battlefield[:bomb_range[1]] + battlefield[bomb_range[2]:]

#battlefield = battlefield[:bomb_range[2]] + battlefield[bomb_range[3]:] #Will not work of course. But how could I achieve what I want?

I am sorry about the nested loops. If it hurts looking at it, feel free to bash and correct me. I am sorry if I missed any answers on this forum which could have helped me find a solution. Know that I did try to find one.

It is completely unclear what you want to do. How, exactly, does the content in airstrikes tell you how to transform reinforces? Show examples of the results you would expect if your transform was successful; given the examples here.

Use index to find where to strike, then remove the character the usual way:

>>> reinforce = "abcdefg"

>>> airstrike = "   *   "

>>> strike_at = airstrike.index('*')

>>> reinforce[:strike_at]+reinforce[strike_at+1:]

'abcefg'

of course, you need to make sure strike_at+1 is a legal index (see try and except).

I thought I needed to do some kind of error handling to check if it was out of bounds. Index seems like a smart solution. I will try it out

@DonutSteve You do. That is why I suggested googling/searching try/except. You could compare to len(airstrike), but that is less idiomatic in Python.
