Hello! I’m doing a histogram in Python, but in the line Histogram = Counter(decile(grids) for grade in grids) I find error with the Counter function. I already did the test using import Collections but I couldn’t. Following the lines developed so far:

grades = [83, 95 ,91, 87, 70, 0, 85, 82, 100, 67, 73, 77, 0]
decile = lambda grade: grade / 10 * 10
histogram = collections.Counter(decile(grades) for grade in grades)
python

Mauro, import is really necessary.

The error is no for inside the Counter, you sent the list and not the list item:

import collections

grades = [83, 95 ,91, 87, 70, 0, 85, 82, 100, 67, 73, 77, 0]
decile = lambda grade: grade / 10 * 10
histogram = collections.Counter(decile(grade) for grade in grades)

  • Thank you Daniel! In this case, what would be the appropriate structure?

Place...

from collections import Counter

  • How he used collections.Counter, the correct would only be import collections. Or failed to supplement your answer by asking how it would be when doing the import as suggested.
