python利用字典进行词频统计

text = "this is a sample text with several words and some of them repeat several times"

# 将文本分割成单词
words = text.split()

# 定义一个空字典，用于记录每个单词的出现次数
word_count = {}

# 遍历每个单词，统计出现次数
for word in words:
    if word not in word_count:
        word_count[word] = 1
    else:
        word_count[word] += 1

# 输出结果
for word, count in word_count.items():
    print(f"{word}: {count}")
