How do I fix ValueError too many values to unpack?
The “valueerror: too many values to unpack (expected 2)” error occurs when you do not unpack all the items in a list. This error is often caused by trying to iterate over the items in a dictionary. To solve this problem, use the items() method to iterate over a dictionary.
What does ValueError not enough values to unpack expected 2 got 1 mean?

Can I return two values from a function?
No, you can not have two returns in a function, the first return will exit the function you will need to create an object.
How do I unzip a tuple?
Use zip() with the * operator to unzip a list of tuples
- zipped = [(“a”, 1), (“b”, 2)]
- unzipped_object = zip(*zipped)
- unzipped_list = list(unzipped_object) Separate paired elements in tuple to separate tuples.
- print(unzipped_list)
