ValueError: too many values to unpack (expected 2)

原代码：

for line in file.readlines():  #every line is a poem
    #print(line)
    title, poem = line.strip().split(":") 

报错信息：

D:\anaconda\envs\tensorflow\python.exe E:/python/21tensorflow项目/word2vec/test1.py
Traceback (most recent call last):
  File "E:/python/21tensorflow项目/word2vec/test1.py", line 5, in 
    title, poem = line.strip().split(":")  #get title and poem
ValueError: too many values to unpack (expected 2)

Process finished with exit code 1

问题原因：

字典是一个迭代器对象，只支持Key的遍历,，如果想对key，value，则可以使用items方法。

解决后的代码如下：

for title,poem in filedic.items():

    title, poem = line.strip().split("::")  #get title and poem
