dict_values to string in python

Question

I simply want to convert an object that looks like this:

dict_values(['baf0242b-d7fc-49d7-aada-220344969fb6'])

That I got from doing this:

dictionary.values()

To a simple string: 'baf0242b-d7fc-49d7-aada-220344969fb6'

How can I?

Answer 1

Say you have a dictionary:

d = {'key': 'baf0242b-d7fc-49d7-aada-220344969fb6'}

The result you see is from running the following:

d.values()

To get what you want, convert it to a list and get the first item on it:

d = {'key': 'baf0242b-d7fc-49d7-aada-220344969fb6'}
result = list(d.values())[0]

Answer 2

list(your_dict.values())[0]

正如@rdas 所提到的， dict_values是 Python 3+ 中的一个view ，第一个索引将返回您的字符串。

Answer 3

If you are getting the first value, or the only value in your case. This might be a bit more memory efficient:

next(iter(d.values())))
