Javascript has a function called `setInterval` which given a length of time $T$ and a callback function, it will perform that function every $T$ milliseconds. For example, to print "Hello, World!" every 5 seconds:
```javascript
setInterval(function() {
console.log("Hello, World!")
}, 5 * 1000)
```
Wouldn't it be nice if Python had a similar functionality? Well thanks to [right2clicky](https://stackoverflow.com/a/48741004), there's a nice and quick way to implement one.
```python
from threading import Timer
class Repeat(Timer):
def run(self):
while not self.finished.wait(self.interval):
self.function(*self.args, **self.kwargs)
```
Since `self.finished.wait` only returns `True` when the Event `self.finished` is set to true, the thread will keep waiting and calling the function for the set interval time period.
