loop adventure game

[ilikedofs]

i am trying to get the loop
to do if user press l go back to previous line
I've looked on the internet and can't find anything that did not pertain to math or advanced projects

if choice=='s':
  print("ok you've choosen  the sword. You see two doors. one is to the left and one is to the right")
  doors=input('Which door do you want to open? l or r ')
 if doors =='r':
     print('you are in an empty room. All there is you and your weapon of choice  ')
 elif doors  =='l':
     print("what are you doing here get out!"",""Some one yells. And punches you and stabs you. You have lost a live")
     lifes=lifes-1
     print('You now have a life total of: ' + int(lifes)

and if I do while True:. it will give me nothing
and now i am getting an error on line 21

Error:
Traceback (most recent call last):
  File "main.py", line 21, in <module>
    print('You now have a life total of: ' + lifes)
TypeError: can only concatenate str (not "int") to str

and here is out put for when i don't have the error and i use while true

Output:

You could either loop here until you get an answer you want, or you might prefer to push it off to another function. If you will have several locations in the code, I'd much rather have it in a separate function.

def get_specific_input(prompt, valid_responses):
    response = input(prompt)
    while response not in valid_responses:
        print(f"Please enter only one of {','.join(valid_responses)}."
        response = input(prompt)
    return response

Here the while loop will continue to prompt until the response matches one of the valid responses. Since it has already done the checking, your main code can just assume that one of the expected choices will be present.

Then you could call it like:

if choice=='s':
  print("ok you've choosen  the sword. You see two doors. one is to the left and one is to the right")
  doors=get_specific_input('Which door do you want to open? l or r ', ['l', 'r'])
 if doors =='r':
