In the provided example, they’re turning it into a map of city names to temps so I kept that. Yours keeps it as an array of objects with a name and temp.
If you skip that,
city_temps
.select { |ct| ct.temp > 20 }
city_temps
.iter()
.filter(|ct| ct.temp > 20 )
.collect();
are still best IMO just due to the natural method chaining of iterators.
- ReleaseCandidat 3y agoOh, yes, of course you're right, I didn't see that until now - did I say already, that I hate Python's list comprehensions or everything not totally simple?. So that needs reduce: def filter_func(acc, e): if e["temp"] > 20: acc[e["city"]] = e["temp"] return acc filtered_temps = functools.reduce(filter_func, temperatures, {})
- Izkata 3y agoTechnically that's a dict comprehension, not a list comprehension (though they are pretty much the same). The old style, before they existed, was to create a list of 2-tuples (key/value pairs) in a list comprehension and pass that to dict().
