如何将计数器值除以设定的数字？

Question

我一直在使用 collections.Counter 计算列表中出现的单词数。然而，我的问题是我现在希望将每个值除以预定数字（在本例中为 14）。但是，我正在尝试以下操作，但收到错误：'str' object has no attribute 'values'，我理解，但不确定如何更正。这是我目前拥有的：

from collections import Counter
mylist = ['red','green','blue','red','orange','red','green']

counts = Counter(mylist)

for word in counts:
    x = word.values()/14

理想情况下，我最终想要的是一个字典列表，其中单词作为键，计数（除以我的预设值）作为值。像

>>> mynewlist = [{'Red', 0.214},{'Green', 0.143},{'Blue', 0.071},{'Orange', 0.071}]

Answer 1

您必须像在普通字典上那样对其进行迭代：

from collections import Counter
mylist = ['red','green','blue','red','orange','red','green']

counts = Counter(mylist)
for item, count in counts.items():
    counts[item] /= 14

print(counts)
# Counter({'red': 0.21428571428571427, 'green': 0.14285714285714285, 
# 'blue': 0.07142857142857142, 'orange': 0.07142857142857142})
