Convert a String representation of a Dictionary to a dictionary

I want to convert the following string into dictionary without using eval() function in Python 3.5.
d="{'Age': 7, 'Name': 'Manni'}";
Can anybody tell me the good way than using the eval() function?
What I really want is a function which can directly convert a dictionary to a string.


literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):
from ast import literal_eval
python_dict = literal_eval("{'a': 1}")
json.loads but it would require your string to use double quotes:
import json
python_dict = json.loads('{"a": 1}')

I have a string that looks like this:
'{"screen_name":"Brian","avatar":1},{"screen_name":"David","avatar":21},{"screen_name":"Teo","avatar":34}'
How can I make it a list of dictionaries?
I tried with json.loads, but it threw an error...

before trying json.loads, you have to make sure that is surrounded by square brackets.
You can achieve that by using format or fstrings, so you can do:
>>> import json
>>> json.loads(f"[{original}]")
[{"screen_name":"Brian","avatar":1},{"screen_name":"David","avatar":21},{"screen_name":"Teo","avatar":34}]

That's literally valid JSON. This works:
import json
my_string = '{"data":[[[""],["2,681,118"]], ...}'
nested_dict = json.loads(my_string)

How to convert string representation of list to a list
(19 answers)
Closed 4 years ago.
How do I split this:
str = "['A20150710', 1.0]" to get 'A20150710'?
I tried the below line but not sure how to proceed from there:
str.split(',')

Use ast.literal_eval to convert string representation to a list and get the first item:
import ast
str = "['A20150710', 1.0]"
print(ast.literal_eval(str)[0])
# A20150710

Split on , and remove punctuations
import string
str1 = "['A20150710', 1.0]"
str1=str1.split(',')[0]
str1.translate(None,string.punctuation) #'A20150710'

Use eval to parse the string, then fetch the information you want
str = "['A20150710', 1.0]"
eval(str)[0] # A20150710
!!!Be careful!!! Using eval is a security risk, as it executes arbitrary Python expressions

How to turn a string into a list in python?
(2 answers)
Closed 8 years ago.
I was wondering if there was a way to take a properly formatted user input array, IE '[2,1,1]' as user input, and then convert that into a int array of [2,2,1].

You could use ast.literal_eval to safely parse a string representing a literal Python expression into a Python object:
import ast
ast.literal_eval('[2,1,1]')
# [2, 1, 1]
If the string is valid JSON, then you could instead use json. loads:
import json
json.loads('[2,1,1]')
# [2, 1, 1]
Of the two, when the string is both a literal Python expression and JSON, json.loads is faster.

How to deserialize complex json string to python object? [duplicate]

Deserialize a json string to an object in python
(12 answers)
Closed 8 years ago.
I need to convert json string to python object. for example,
{
"person":{
"name":"aa",
"age":"12",
"address":{
"city":"cc",
"road":"kk"
}
}
}
there are two python class Person and Address used to generate python object. but I don't know how to map it.

You can easily convert the JSON string to a native Python dictionary with json.loads:
import json
d = json.loads(s)
It is not clear what arguments your Person and Address take, but if they take keyword arguments matching the dictionary content it could be as simple as:
d['address'] = Address(**d['address'])
p = Person(**d)
Where ** unpacks the dictionary into keyword arguments.

You can do this in a couple ways. One way is the simplejson literal translation. I would say the cleanest way of creating an extensible method is creating a class with that same structure.
