] | A slightly more Pythonic way would be to use a generator instead:
```
sum(1 for x in frequencies if x > 0)
```
This avoids generating the whole list before calling `sum()`. | How about this?
`reduce(lambda x, y: x+1 if y > 0 else x, frequencies)`

2,900,084 | I have a list of integers and I need to count how many of them are > 0.
I'm currently doing it with a list comprehension that looks like this:
```
sum([1 for x in frequencies if x > 0])
```

] | If you want to reduce the amount of memory, you can avoid generating a temporary list by using a generator:
```
sum(x > 0 for x in frequencies)
```
This works because `bool` is a subclass of `int`:
```
>>> isinstance(True,int)
True
```
and `True`'s value is 1:
```
>>> True==1
True
```
