I like the concept of watchr: it monitor the file system and run a callback when something changes. Is there a pure Python equivalent? Preferably pip installable.
回答1:
You should probably look at watchdog:

For Windows, there's watcher, that is probably close to what you need although I'm not sure it provides 100% equivalent information.
