python报错

1、

word_freq = {}
for word in words:
    if word in word_freq:
        word_freq[word] += 1
    else:
        word_freq[word] = 1
for i in range(word_freq):
    print(word)
    print(word_freq[word])

TypeError: 'dict' object cannot be interpreted as an integer
类型错误:'dict'对象不能被解释为整数

在打印字典的键值对时出现上述错误，首先是word没有参与循环，其次range(word_freq)使用错误

word_freq = {}
for word in words:
    if word in word_freq:
        word_freq[word] += 1
    else:
        word_freq[word] = 1
for word, freq in word_freq.items():
    print(word,word_freq[word])
