Printing a string with a little delay between the chars

Question

I want a text to be displayed as if it is just being typed. So I need a little delay after every letter.

I tried to do it this way:

import time

text         


        

Answer 1

You are printing the result of time.sleep(0.2), which is None. Move it to the next line.

text = "Hello, this is a test text to see if all works fine."
for char in text:
    print char,
    time.sleep(0.2)

Of course, you still have the problem of a space between each character, which can be solved by replacing the print statement with a call to sys.stdout.write.

text = "Hello, this is a test text to see if all works fine."
for char in text:
    sys.stdout.write(char)
    time.sleep(0.2)
