words = ['python','hadoop' ,'spark' ,'hello' ,'python' ,'hello', 'spark', 'love', 'spark', 'learn', 'hadoop', 'love', 'spark', 'love', 'hadoop', 'hello', 'python', 'spark', 'is', 'good','python','is','good','hadoop']
words_1 = {} #利用字典统计词频
for word in words:
count = 0
if word in words: #使用in的话，出现一次为真，将会直接跳过，相当于去重
count = words.count(word) #count函数算出出现次数作为valus
words_1[word]=[count]
print(words_1)
运行结果如下：
