Question

您好，我想知道如何制作一个不计单词'the'的字典，或者绝对不将其从字典中删除，所以我想出了这段代码：

counts = dict()
print('Enter a line of text:')
line = input('')
words = line.split()
print('Words:', words)
print('counting...')
for word in words :
    if words != 'the':
        counts[word]= counts.get(word,0)+1
    else:
        counts[word] = counts.get(word,0)
print('Counts', counts)

您能帮我做对吗？

Answer 1

@Steve的答案是正确的，但是代码可以美化和简化：

from collections import Counter

line = input('Enter a line of text:')
words = line.split()

print('Words:', words)
print('counting...')

c = Counter(words)
del c['the'] # remove 'the' key from counter

print('Counts', dict(c))
