Print sync

• First let's see a few small and useless examples.
• In this example we use sleep to imitate some external task we need to wait for and then we print out some text.
• We do it sequentially. No async here.

The code

import time

def say(text, sec):
    time.sleep(sec)
    print(text)

def main():
    start = time.monotonic()
    say("First", 2)
    say("Second", 1)
    end = time.monotonic()
    print(f"Elapsed: {end-start}")

main()

Output

First
Second
Elapsed: 3.0015416080132127

So it takes slightly more than 3 seconds to wait first for 2 and then for 1 second. No big surprise there.
