A Simple Loading Animation For the Command Line Using Python 3

Loading.py

"""
  This program is designed to create
  and animate a simple loading animation.

from sys import stdout as terminal
from time import sleep
from itertools import cycle
from threading import Thread

done = False

def animate():
    for c in itertools.cycle(['|', '/', '-', '\\']):
        if done:
            break
        terminal.write('\rloading ' + c)
        terminal.flush()
        sleep(0.1)
    terminal.write('\rDone!    ')
    terminal.flush()

t = Thread(target=animate)
t.start()
sleep(5)
done = True

Line 14 should be for c in cycle(['|', '/', '-', '\\']): without the "itertools". After that this will work just fine.

either way, it works fine. but you're way is much cleaner

Thanks for sharing. some CLIs like mine will also print a % after "Done!". I added + "\n" to get rid of it. So terminal.write('\rDone! '+ "\n" )

Made some improvements (turned into decorators, added custom text, added proposition from @k-blo .
