Add single quotes to a variable in Python

Question

I have a variable that looks like this:

data = {"add_content": {"errata_ids": [advisory]},"content_view_version_environments": [{"content_view_version_id": version_id}]}

I need to add single quotes to this variable , ie if I will assign the variables:

advisory and version_id and add the single quotes to data variable like this:

data = '{"add_content": {"errata_ids": ["RHSA-2017:1390"]},"content_view_version_environments": [{"content_view_version_id": 160}]}'

I am able to post to the API

I have tried to add the single quotes in variety of ways:

new_data = "'" + str(data) + "'"
>>> new_data
'\'{\'add_content\': {\'errata_ids\': [\'"RHSA-2017:1390"\']}, \'content_view_version_environments\': [{\'content_view_version_id\': \'160\'}]}\'' 

or using:

'"%s"'%(data)

and a few more ways.

How can I add the single quotes to the outer to the data variable before and after the opening { and closing } ?

Answer 1

This is exactly what JSON does:

import json
new_data = json.dumps(data)

如果与之前的答案和注释相反，您没有尝试转换为json字符串，那么请在变量周围使用string.format：

data = {"add_content": {"errata_ids": '[{}]'.format(advisory)},"content_view_version_environments": [{"content_view_version_id": '{}'.format(version_id)}]}
