Yes, that works, and I’ve used that on a couple of projects.
Another alternative is defining an Abstract Base Class,
https://docs.python.org/3/library/abc.html, and having an institution-specific
implementation passed into your module.

Moving the generator out:
import timeit
thedata = [i for i in range(1_000_000)]
def sum1():
s = 0
for i in thedata:
s += i
return s
def sum2():
return sum(thedata)
print('For Loop Sum:', timeit.timeit(sum1, number=100))
print( 'Built-in Sum:', timeit.timeit(sum2,
Sum is faster than iteration in the general case.

I don't remember making such a mistake ever before, but it might have
happened. -= is a convenient operator so I've probably used it a lot.
Anyway, I found that flake8 flagged this as
E225 missing whitespace around operator
and it's the only linter of pylint, flake8 and pyflake that detects

Root would install the script and required Python version somewhere

I can't remember any details offhand, but I know I've occasionally
made use of the ability to do this. It's fine as long as the method
you're calling doesn't rely on anything you haven't initialised yet.
The following code won’t be allowed in Java, but in python, it works fine:
```python
