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

This error occurs when you try to unpack too few values from an iterable object (such as a list or tuple).

For example, if you have a tuple with two elements and try to unpack it into two variables, but only provide one variable, you will get this error:

tuple = (1, 2)
x, y = tuple  # This will work
x = tuple     # This will also work
x, = tuple    # This will raise a ValueError: not enough values to unpack (expected 2, got 1)

In the last line, you are trying to unpack the tuple into one variable (`x`), but the tuple has two values. Therefore, you get a ValueError because there are not enough values to unpack.

To fix this error, make sure you are unpacking the correct number of values. If you don't need all the values in the iterable, you can use the syntax `x, _ = tuple` to ignore the second value.
