Key-Value Assignment via list comprehension in python

Question

For a school assignment, I have to adapt a given code but keep the dictionary comprehension mechanism in Python. Given my code

dct = {k: v for k in ["HELLO", "SLEEPING"] for v in ["WORLD", "CITY"]}
print(dct["HELLO"])

the printout is "CITY". How do I have to adapt the code to get "WORLD" returned? Thank's a lot!

`dict(zip(["HELLO", "SLEEPING"],["WORLD", "CITY"]))`? – Chris Jun 09 '20 at 08:23 — Chris, Jun 09 '20 at 08:23

Use zip

dct = {k: v for k, v in zip(["HELLO", "SLEEPING"], ["WORLD", "CITY"])}
print(dct["HELLO"])

And if you can get rid of the dictionary comprehension:

dct = dict(zip(["HELLO", "SLEEPING"], ["WORLD", "CITY"]))
