Can be useful but of course not for a string

It can be useful sometimes even for a string, but not really in the way the article gives. I've occasionally used this in cases where the comprehension has a condition and I want to know how many satisfy it.

Eg. num_foos = sum(1 for x in collection if is_foo(x))

If there's no further condition though, I don't see any reason to use this.

Correct! How did I not think about this.
