1,002 PointsPython: How can you print strings one character at a time?
Hey,
I've been practising python by writing a little text based adventure game. I'm trying to find a way to print out the dialogue in the game one character at a time, kind of like the old pokemon gameboy games.
I've looked around but can't find anything that works. I guess I have to define a function for the print that uses time, which has a sleep(0.02) between each character. Maybe using a loop to pick out each len() in the text and print them? Or convert the string into a list and print it that way?
Very new to python so all help appreciated.
Thanks a lot!

import time
for x in "my string":
print(x, end='')
time.sleep(0.05)
By default, end is a newline, therefore Python by default prints a newline after the string, but you can easily change it to have no ending.

10,365 PointsHi Peter, I am not sure I understand your question but here is a very basic code that prints a string one character after another.
import time
import sys
string = "Some sting"
for char in string:
# these two lines prevent python from including a new line after every character
sys.stdout.write(char)
sys.stdout.flush()
time.sleep(0.500)
Let me know what you think ...

10,365 PointsHi Peter, you have been asking for a method that does the same thing.
import time
import sys
word = "Some sting"
def character_timer(string):
for char in string:
sys.stdout.write(char)
sys.stdout.flush()
time.sleep(0.500)
character_timer(word)
I hope that helps
