In raw_input() appears at the end "none"

Question

By printing out of raw_input() appears at the end a "none".

I defined above a function to look nice when printing the question.

Here's my code:

def delay_print_input(string):
  for c in string:
    sys.stdout.write(c)
    sys.stdout.flush()
    time.sleep(0.15)

ans=raw_input(delay_print_input("What do you want?\n>> "))

The output looks like:

What do you want?
>> None

My question is, how can I remove this none?

you should use a return statement in the end of the function that you have defined — babygame0ver, Dec 14 '17 at 15:29

Your function returns None, which raw_input then prints. What you want is this:

def delay_print_input(string):
  for c in string:
    sys.stdout.write(c)
    sys.stdout.flush()
    time.sleep(0.15)

delay_print_input("What do you want?\n>> ")
ans=raw_input()

Your function is returning None and sending it to the input function. You can just return a blank string in your function

def delay_print_input(string):
    for c in string:
        sys.stdout.write(c)
        sys.stdout.flush()
        time.sleep(0.15)
    return ""

In raw_input() appears at the end "none"
