How to add "?" sign if the sentence type is questions-CodePudding

I have a list. In this list have various type of sentences suppose question type and general sentences. I want to add question mark "?" sign after end of the sentence if it it is question.

Here is my list

lst = ['what is Fame', 'how can you start work', 'can you learn design', 'this is text']

I tried this code

for i in lst:
if 'what' or 'how' or 'can' in lst:
    print(i, '?')

But not getting my desired output.

I would like to achieve:

what is Fame?
how can you start work?
can you learn design?

Could anyone please help me to do this?

Thanks, everyone!

You can achieve the desired output by checking if sentence in list startswith with a specific word. If yes, you can print a question mark at the end:

lst = ['what is Fame', 'how can you start work', 'can you learn design', 'this is text']

for phrase in lst:
    if phrase.startswith('what') or phrase.startswith('how') or phrase.startswith('can'):
        print(phrase   '?')

You can also make your own startswith, which is just some simple use of Python's great slicing notation.

def startswith(s, initial):
  return s[0:len(initial)] == initial

Building on Dan's answer:

def startswith(s, initial):
  return s[0:len(initial)] == initial

lst = ['what is Fame', 'how can you start work', 'can you learn design', 'this is text']

for phrase in lst:
    if startswith(phrase, 'what') or startswith(phrase, 'how') or startswith(phrase, 'can'):
        print(phrase   '?')

It is not advisable to extend the built in String with your own stuff, but it can be done.
