fin - adding a bit more awesome to python¶

About¶

Fin is a small utility library for Python. It has several modules for doing common things, with a focus on keeping users’ code clean and simple. With fin (fin.contextlog), producing the following is trivial:

Source¶

The above graphic was produced by the following code:

import fin.contextlog
import functools

Log = functools.partial(fin.contextlog.Log, theme="mac")

...

def main():
    left = 10
    with Log("Processing Users"):
        for user in NAMES:
            with Log(user):
                with Log("Creating account"):
                    time.sleep(random.random()/4)
                with Log("Setting up homedir"):
                    time.sleep(random.random()/4)
                with Log("Creating primary key") as l:
                    time.sleep(random.random()/5)
                    left -= 1
                    if left == 0:
                        raise RuntimeError("Not enough entropy")
                    l.output(random.choice(keys).strip())


if __name__ == '__main__':
    main()
