ValueError: not enough values to unpack (expected 2, got 1)

This error occurs when you are trying to unpack a sequence (such as a tuple or a list) into multiple variables, but the sequence does not contain enough elements to match the number of variables.

For example:

x, y = (1,)

In this case, we are trying to unpack a tuple with only one element into two variables, which is not possible. To fix this error, we need to make sure that the sequence we are trying to unpack has the correct number of elements.

Here's an example of how to avoid this error:

x, y = (1, 2)

In this case, we have a tuple with two elements, which can be unpacked into two variables successfully.
