will help you Using dict comprehension:
code :
>>> values = [
...     ["SomeValue1", "Key1"],
...     ["SomeValue2", "Key2"],
... ]
>>> {x[1]: x for x in values}
{'Key2': ['SomeValue2', 'Key2'], 'Key1': ['SomeValue1', 'Key1']}

django/python convert string which represents a python dictionary into a dictionary object

should help you out ast.literal_eval is a very restricted, safer eval that only evals literals (e.g. dicts, tuple or list literal containing string, int, float, ... literals).
A JSON parser would work as well for an even more restricted subset (bools are different, null instead of None, no tuples, perhaps even more). Again, the standard library can do this (and there are third party solutions for older Python versions).

wish help you to fix your issue I have unicode u"{'code1':1,'code2':1}" and I want it in dictionary format. , You can use built-in ast package:
code :
import ast

d = ast.literal_eval("{'code1':1,'code2':1}")

like below fixes the issue You need to pass the return value of the first lookup into a lookup for the second:
code :
dict2[dict1[1]]
>>> dict1 = {1:'apple', 2:'mango', 3:'pear'}
>>> dict2 = {'apple': 'jason', 'mango': 'mary', 'pear':'susan'}
>>> dict1[1]
'apple'
>>> dict2['apple']
'jason'
>>> dict2[dict1[1]]
'jason'

Hope that helps I have a following string in python. I need to convert this into a dictionary. , Following code solved the problem,
code :
myDict = dict()
split_params = params.split('=')
split_param_len = len(split_params)
index = 0
m_key = m_val = None 
while index < split_param_len:
    inner_split = split_params[index].rsplit(",", 1)
    for tem_split in inner_split:
        if m_key is None:
            m_key = tem_split
        elif m_val is None:
            m_val = tem_split

        if m_key and m_val:
            myDict[m_key] = m_val
            m_key = m_val = None
    index += 1

fixed the issue. Will look into that further You can use regular expressions to process the string to add in the quotes before trying to evaluate:
code :
import re
import ast

s = "{source: s3, aws_access_key_id: myaws, aws_secret_access_key: REDACTED_POSSIBLE_AWS_SECRET_ACCESS_KEY, bucketName: bucket, region_name: eu-west-1, fileType: zip, typeIngestion: FULL, project: trackingcampaigns, functionalArea: client, filePaths: [s3Sensor/2018/], prefixFiles: [Tracking_Sent, Tracking_Bounces, Tracking_Opens, Tracking_Clicks, Tracking_SendJobs], prefixToTables: {Tracking_Bounces: MNG_TRACKING_EXTRACT_BOUNCES_3, Tracking_Sent: MNG_TRACKING_EXTRACT_SENT_3, Tracking_Clicks: MNG_TRACKING_EXTRACT_CLICKS_3, Tracking_Opens: MNG_TRACKING_EXTRACT_OPENS_3, Tracking_SendJobs: MNG_TRACKING_EXTRACT_SENDJOBS_3}, stagingPath: /zipFiles/}"

s = re.sub(r':\s?(?![{\[\s])([^,}]+)', r': "\1"', s) #Add quotes to dict values
s = re.sub(r'(\w+):', r'"\1":', s) #Add quotes to dict keys

def add_quotes_to_lists(match):
    return re.sub(r'([\s\[])([^\],]+)', r'\1"\2"', match.group(0))

s = re.sub(r'\[[^\]]+', add_quotes_to_lists, s) #Add quotes to list items

final = ast.literal_eval(s) #Evaluate the dictionary

print(final)
