Creating a Function to find dictionary entries
"person_forms" is a list of dictionaries.
It contains:
[{'Name': 'Thor','Username': 'bkpn1412', 'DOB': '31.07.1983', 'Country': 'Norway']},
{'Name': 'Franco','Username': 'gqjs4414', 'DOB': '27.07.1998', 'Country': 'Spain'}]
Using a function(which takes one argument), how can I return the dictionary entry which has Username == gqjs4414? (the 2nd entry)
for example: If i call the function with the username value:
find_person('gqjs4414')

I've done it ,
Hi Jaiswal!
Thanks for your reply.
I'd say it depends on the context whether you'd need a function to obtain the first dictionary, while you can also just use indexing.
Let's say you want to call your dictionary in the following way:
dict_1 = [{'Name': 'Thor','Username': 'bkpn1412', 'DOB': '31.07.1983', 'Country': 'Norway'},
{'Name': 'Franco','Username': 'gqjs4414', 'DOB': '27.07.1998', 'Country': 'Spain'}]
Then, you can obtain its first element with indexing:
dict_1[1]
Alternatively, here's a function I think can deliver what you are aiming for:
def obtain_first(x):
print (x[1])
Finally, you can execute:
obtain_first(dict_1)
Hope this helps.
Best,
Martin
