![]() ![]() The second example doesn’t throw an error because the number of assignment variables matches the number of values in the list. The first example throws an error because there are only two assignment variables (a, b). In the code block above, there are two examples of unpacking a list. ![]() Let’s take a look at how we can fix the error when working with lists: # Fixing ValueError: Too Many Values to Unpack in PythonĪ, b, c = vals # Doesn't Raise ValueError The most common cause of the “too many values to unpack” error is when you try to assign more (or fewer) variables than there are elements in a list (or a tuple). In this section, we’ll discuss how to fix this error specifically with lists in Python. This error is common when working with lists, especially when the number of elements in the list doesn’t match the number of variables you’re trying to assign them to. If you’re getting a “ValueError: too many values to unpack” error in Python, it means that you are trying to unpack more values than there are variables. Fix ValueError: Too Many Values to Unpack with Lists in Python Let’s now dive further into this and other causes of this error. Let’s take a look at how to resolve it below: # Resolving ValueError: Too Many Values to Unpack in Python In order to resolve the error, we need to match the number of variables we assign with the number of values in the iterable. # ValueError: too many values to unpack (expected 2) Let’s take a look at an example that throws the error: # Raising ValueError: Too Many Values to Unpack in Python In order to resolve the error, you simply need to match the number of assignment variables to the number of values in an iterable.
