How can I make this repeat forever?

Question

I have this code which generates random characters (it's a kind of terrain generator). I just can't get it to print forever. Here's the current code I have for it:

import random
print(' '.join([random.choice(['#','o','~','*']) for i in range(10000)]))

I tried to do this, but I got a SyntaxError.

import random
print(' '.join([random.choice(['#','o','~','*']) while True]))

How can I get this to repeat forever? I also want a 0.05 second delay in between the printing of each character.

Answer 1

Well, if you want a delay between the characters, you can't use join() because that will give you a single string instead of a "character generator".

And if you plan on using an "infinite" generator, you can't use join() either for that same reason.

How about this:

import random
import sys
import time
while True:
    print(random.choice("#o~*"), end="", flush=True) # Python 3.3 and up
    time.sleep(0.05)
