Typeerror: cannot unpack non-iterable nonetype object

A common cause of this error is when you try to unpack values from a function that does not return a value. To solve this error, make sure the value you are trying to unpack is a sequence, such as a list or a tuple. What does this error mean? I get this

Explore your training options in 10 minutes Get Started. Python sequences can be unpacked. This means you can assign the contents of a sequence to multiple variables. In this guide, we break down what this error means and why you may see it. We discuss an example of this error in action so you can figure out how to solve it. Unpacking syntax lets you assign multiple variables at the same time based on the contents of a sequence.

Typeerror: cannot unpack non-iterable nonetype object

This error often arises due to incorrect variable assignments, function returns, or unexpected results from external sources. In this article, we will explore some code examples that demonstrate situations leading to this error and how to handle them effectively. When attempting to unpack values from None , the error occurs. If the API request fails status code not , it returns None. Coders can avoid this issue and guarantee that their Python code runs smoothly by carefully inspecting the return values, and proper error handling. Skip to content. Change Language.

When you're working with iterable objects like Lists, Sets, and Tuples in Python, you might want to assign the items in these objects to individual variables. This is a process known as unpacking. During the process of unpacking items in iterable objects, you may get an error that says: "TypeError: cannot unpack non-iterable NoneType object". This error mainly happens when you try to assign an object with a None type to a set of individual variables. This may sound confusing at the moment, but it'll be much clearer once we see some examples. Before that, let's talk about some of the key terms seen in the error message. We'll discuss the following terms: TypeError, unpacking, and NoneType.

The Python error message cannot unpack non-iterable NoneType object typically occurs when we try to unpack a None value as if it were an iterable object. In this guide, we'll explore what this error means, why it occurs, and how to fix it. The first part of the message tells us that we've encountered a TypeError , which is an error that occurs when we try to perform an operation on a value of the wrong type. The second part of the message tells us that we're trying to unpack a non-iterable NoneType object. In Python, an iterable is an object that can be looped over, such as a list , tuple , or dictionary. And unpacking refers to extracting values from an iterable object and assigning them to individual variables. We then unpack the tuple into variables a , b , and c using the assignment statement. Each value in the tuple is assigned to a separate variable, which we can then use in our program.

In this guide, we break down what this error means and why you may see it. We discuss an example of this error in action so you can figure out how to solve it. Unpacking syntax lets you assign multiple variables at the same time based on the contents of a sequence. Consider the following code:. The unpacking syntax only works on sequences, like lists and tuples. You cannot unpack a None value because None values are not sequences.
