Capitalize letter after exclamation mark

Question

I have string that needs to be capitalized after "!":

I have made a script that works to a certain extent but gives me a problem when the last letter is "!".

strin "hello! there!" 

strout = []

for i in range(len(strin)):     
    if strin[i-2] == '!':
        strout.append((strin[i]).capitalize())

    else:
        strout.append(strin[i])
    strout[0] = strout[0].capitalize()

newStr = "".join(strout)

Output is: HEllo! There!

What can I do to prevent the second letter to be capitalized.
The reason for [i-2] is whenever the loop encounters a '!' in the middle of text it capitalizes the letter i.

Answer 1

a simple solution would be to capitalize only if i-2 >= 0.

try this:

strin = "hello! there!"

strout = []

for i in range(len(strin)):
    if i-2>=0 and strin[i-2] == '!':
        strout.append((strin[i]).capitalize())
    else:
        strout.append(strin[i])
strout[0] = strout[0].capitalize()

newStr = "".join(strout)

print(newStr)
