AttributeError: 'list' object has no attribute 'values'

[ilknurg]

I have a query. My query returns the result that i want as a dictionary.

Like:

[{'community_string': 'public'}, {'community_string': 'private'}]

I want to use only public and private as a string. For doing it, i wrote my code like that:

query= "SELECT community_string FROM nat_snmp_string WHERE status ='enable'"
cursor = connection.cursor(dictionary=True)
cursor.execute(query)
com_str = cursor.fetchall()
com_str_string = com_str.values()
cmnyt_str = json.dumps(list(com_str))
print(cmnyt_str)  
cmd_line = cmnyt_str.replace(':','')
cmd_line = cmd_line.replace('"','')
cmd_line = cmd_line.replace(']','')
cmd_line = cmd_line.replace('[','')
  

but it gives me AttributeError: 'list' object has no attribute 'values' error.
How can i solve this issue?
Thank you for your helps.

The error is from trying to access a list like a dict.

you can use the list index to access the data or loop the list to get the data.

com_str = [{'community_string': 'public'}, {'community_string': 'private'}]

print('list index')
print(f"{com_str[0]['community_string']} | {com_str[1]['community_string']}")

print()
print('looping')
for data in com_str:
    print(data['community_string'])

print()
print('One liner')
print('\n'.join([data['community_string'] for data in com_str]))

Output:
list index
public | private

looping
public
private

One liner
public
private

Thank you for your answer. But in my db, there may be more than 2 attribute. In this case i cant write all like that:

com_str = [{'community_string': 'public'}, {'community_string': 'private'}]
 
print(f"{com_str[0]['community_string']} |

{com_str[1]['community_string']}")

Thank you very much!

Then you will need to use some type of loop
