how do i create a list when retrieving a list from a dictionary

Question

I am looking up a set of email addresses grouped together in a dictionary using the get() function

the get function returns

['[“one.yahoo.com”,”two.yahoo.com”,"three.yahoo.com"]']

I have tried several methods to remove the single quotes so that I end up with a list like this

email = [ [“one.yahoo.com”,”two.yahoo.com”,"three.yahoo.com"] ]

the dictionary looks like this

dict= { 'Warehouse':'[“x@yahoo.com”,”y@yahoo.com”,”z@yahoo.com”]', 'Bottling':'[“one.yahoo.com”,”two.yahoo.com”,"three.yahoo.com"]'}

just wanted to check that do you need list inside list or just return list? — Akash senta, Jan 29 '21 at 06:18
if only list required you can just do it with json.loads(listA[0]). So it will convert string into dictionary. or you can do json.dumps(listA[0]) for json. — Akash senta, Jan 29 '21 at 06:19
you can try json.loads(listA[0]) as suggested by akash senta or you can try to use eval as eval(listA[0]) — ravishankar chavare, Jan 29 '21 at 06:21

it will be better to answer if you are adding a sample of dictionary — ravishankar chavare, Jan 29 '21 at 06:23

Try this:

import ast # This contains a function to convert str to list
email = ['["one.yahoo.com", "two.yahoo.com", "three.yahoo.com"]']
email = str(email) # Converts to str type.
email = email.replace("'", "") # Replaces the apostrophes with blanks.
email = ast.literal_eval(email) # Converts to list. 
print(email)

Output is:

[["one.yahoo.com", "two.yahoo.com", "three.yahoo.com"]]

Fixed that. ast should convert it back to list. – Ismail Hafeez Jan 29 '21 at 06:31

You can try this:

email = ['["one.yahoo.com","two.yahoo.com","three.yahoo.com"]']

email = email[0].replace('"','')
email = email[1:-1].split(",")

Hope this may be of help.
