我正在尝试打印在此代码部分中按<!DOCTYPE html>

排序的字典：
value当我尝试运行程序时，我得到以下内容：
for key,value in frequency.items():
output = key + ' : ' + str(value)
sorted_output = sorted(output.items(), key=operator.itemgetter(1))
print sorted_output
我该如何解决这个问题？
感谢。
答案 0 :(得分：2)
您正在将键值对转换为字符串，而字符串没有.items（）。所以它给出了错误。
试试这个：
from operator import itemgetter
for k, v in sorted(frequency.items(), key=itemgetter(1)):
print k, v
