Add to python list without quotations

Question

How can I add to my python list without quotations that cause a json error?

classes["class1"] = "{'key1': 1, 'key2': 2, 'key3': 3}"

Thats what I get:

  'class1': "{
      'key1': 1,
      'key2': 2,
      'key3': 3
  }"

Answer 1

import ast 

classes["class1"] = ast.literal_eval("{'key1': 1, 'key2': 2, 'key3': 3}")

Answer 2

Try this:

>>> def print_sameline():
...     list = [1,2,3]
...     print("List: ",end="")
...     print(*list,sep=",")
... 
>>> print_sameline()
List: 1,2,3

Answer 3

import json
classes={}
classes["class1"] = json.loads("{'key1': 1, 'key2': 2, 'key3': 3}".replace("'",'"'))
print(classes["class1"])

Answer 4

Use ast.literal_eval to parse the string "{'key1': 1, 'key2': 2, 'key3': 3}" to a dictionary.

In [18]: classes["class1"] = ast.literal_eval("{'key1': 1, 'key2': 2, 'key3': 3}")

Note that you cannot use json.loads here due to the single quotes in your string

In [20]: import json                                                                                                                                                                                    

In [21]: classes = {}                                                                                                                                                                                   

In [22]: classes["class1"] = json.loads("{'key1': 1, 'key2': 2, 'key3': 3}")
