ValueError not enough values to unpack expected 4 got 1

This error occurs when you are trying to unpack a sequence of values into a set of variables, but the number of values in the sequence doesn't match the number of variables you are trying to unpack them into. In this case, you are expecting 4 values, but only getting 1.

For example, let's say you have the following code:

x, y, z, w = [1]

This code is trying to unpack the list [1] into four variables x, y, z, and w. However, the list only contains one value, so there aren't enough values to unpack into all four variables. This will result in a ValueError with the message "not enough values to unpack (expected 4, got 1)".

To fix this error, you need to make sure that the number of values in the sequence matches the number of variables you are trying to unpack them into. For example, you could change the above code to:

x, y, z, w = [1, 2, 3, 4]

Now there are four values in the list, so they can be unpacked into the four variables without issue.
