如何从 python 的字段中提取特定数据进行打印？

Question

I'm using the discord.py API to build a bot to show me by different commands the results of some votes. For example, I have a question of Do you like fruit? And the options yes and no. I want to show by screen when you use the.votes command that the option 1 (yes) has 3 votes and the option 2 (no) has 1, The problem is that the variable that contains the number of votes is not an individual variable nor it gives it to me in JSON format. but in Field format (any): This returns postman when I make the request:

"res": "OrderedDict([('option', 'Yes'), ('number', 2), ('votes', 3)), OrderedDict([('option', 'No'), ('number', 1), ('votes', 1))"

From this, I only want the command to use the 'votes' part, but I don't know how to extract it from the string.

I extracted the other data from the other fields like this:

data = v.json()[1]
voter = data['voter']

since they are JSONField. But I don't know how to do it with the other form.

Could you please help me?

EDIT: I tried using this code I've seen in some questions here

 for line in res.split('OrderedDict'):
        vote = re.match(".*'votes',(\d+)", line)
        print(vote.group(1))
 

but it doesn't work either.

Thank you in advance

I'm not familiar with the discord API, but it looks like you've got a library returning an OrderedDict() . You should be able to treat this more or less equivalently to a normal Python dict, and retrieve values by key:

from collections import OrderedDict
choice = OrderedDict([('option', 'Yes'), ('number', 2), ('votes', 3)]) 
n_votes = choice['votes']
print(n_votes)
# 3

By the way, the example you've posted is broken somehow. The brackets are not balanced - could be a faulty copy-paste.
