How to use join method for a list of dictionaries and then add a string for the value

February 15, 2024

This is a list of dicts:

list1 = [
    {'unique_id': '1qaz2wsx', 'db_id': 10},
    {'unique_id': '2qaz2wsx', 'db_id': 20},
    {'unique_id': '3qaz2wsx', 'db_id': 30},
    {'unique_id': '4qaz2wsx', 'db_id': 40},
]

I’m trying to have like this as expected output:

unique 1qaz2wsx, url http://url.com/10
unique 2qaz2wsx, url http://url.com/20
unique 3qaz2wsx, url http://url.com/30
unique 4qaz2wsx, url http://url.com/40

I googled for this but I couldn’t find any hints up to now to how to do this. I mean I may googled the incorrect words, so I don’t have any codes and attempts.

How can I have the expected output?

>Solution :

Try this:

list1 = [
    {'unique_id': '1qaz2wsx', 'db_id': 10},
    {'unique_id': '2qaz2wsx', 'db_id': 20},
    {'unique_id': '3qaz2wsx', 'db_id': 30},
    {'unique_id': '4qaz2wsx', 'db_id': 40},
]

output = '\n'.join([f"unique {d['unique_id']}, url http://url.com/{d['db_id']}" for d in list1])

print(output)

OUTPUT:

unique 1qaz2wsx, url http://url.com/10
unique 2qaz2wsx, url http://url.com/20
unique 3qaz2wsx, url http://url.com/30
unique 4qaz2wsx, url http://url.com/40
