如何在python中从整列字符串中找到最常用的单词

text = "This is a sample sentence. This sentence contains some words."
words = text.split()

word_count = {}
for word in words:
    if word in word_count:
        word_count[word] += 1
    else:
        word_count[word] = 1

most_common_word = max(word_count, key=word_count.get)

print("The most common word is '{}' with a count of {}.".format(most_common_word, word_count[most_common_word]))

text = "This is a sample sentence. This sentence contains some words."
words = text.split()

word_count = {}
for word in words:
    if word in word_count:
        word_count[word] += 1
    else:
        word_count[word] = 1

most_common_word = max(word_count, key=word_count.get)

print("The most common word is '{}' with a count of {}.".format(most_common_word, word_count[most_common_word]))

The most common word is 'sentence' with a count of 2.
