Python:在嵌套字典中创建一个单词统计字典

def count_words(text):
    words = text.split()
    word_count = {}
    for word in words:
        if word not in word_count:
            word_count[word] = {'count': 1}
        else:
            word_count[word]['count'] += 1
    return word_count

text = "This is a sample text. This text contains some words."
word_count = count_words(text)
print(word_count)

{
    'This': {'count': 2},
    'is': {'count': 1},
    'a': {'count': 1},
    'sample': {'count': 1},
    'text.': {'count': 1},
    'text': {'count': 1},
    'contains': {'count': 1},
    'some': {'count': 1},
    'words.': {'count': 1}
}
