My experience is that if you have your "customer" try their hand on
programming and complete a simple challenge, they'll be extremely
impressed. "Did I manage that?"
On the other hand, if you want to demo your greatest achievements at the
screen, they will be left unmoved. "Even my favorite Zynga game looks
cooler than that."

I would advise steering clear of the REPL and go directly to writing a
program and executing it. Maybe the classic ASCII graphics presentation
of the sine wave:
========================================================================
#!/usr/bin/env python3
import time
import math
def main():
for angle in range(0, 100000, 5):
print(int((1 + math.sin(math.radians(angle))) * 35) * "*")
time.sleep(0.1)
if __name__ == "__main__":
main()
========================================================================

I'd recommend not skipping the traditional boilerplate (see my example).
Be professional from the start.
