Fix Cannot Unpack Non-Iterable Int Object
There is an issue with the way you’re trying to unpack your object. Your program must have values that can be iterated, or else it won’t work!
This implies you can dole out the substance of an arrangement to different factors.
In the event that you attempt to unload a None worth utilizing this sentence structure, you’ll experience the “TypeError: can’t unload non-iterable NoneType object” error.
Explanation
Unpacking syntax allows you to allocate numerous factors simultaneously dependent on the substance of a succession.
Think about the accompanying code:
fruit_sales = [230, 310, 219] Avocado, bananas, apples = fruit_sales
This code allows us to dole out the qualities in the fruit_sales variable to three separate factors.
The worth of “avocado” becomes 230, the worth of “bananas” gets 310, and the worth of “apples” gets 219.
The unloading language structure just deals with successions, similar to records and tuples.
You can’t unload a None worth since None qualities are not successions.
This mistake is ordinarily raised in the event that you attempt to unload the consequence of a capacity that does exclude a bring proclamation back.
Example:
We will make a program that ascertains the normal price tag at a bistro and the biggest buy made on a given day.
Start by characterizing a rundown of buys made on a specific day:
Buys = [2.30, 3.90, 4.60, 7.80, 2.20, 2.40, 8.30]
Then, characterize a capacity.
This capacity will compute the normal price tag and the biggest buy made on a given day:
def calculate_statistics(purchases):
average_purchase = int(sum(purchases)) / int(len(purchases))
largest_purchase = max(purchases)
print("The normal buy was ${}.".format(round(average_purchase, 2)))
print("The biggest buy was ${}.".format(round(largest_purchase, 2)))
return average_purchase
print(calculate_statistics(Buys))
To ascertain the normal worth of a buy, partition the absolute worth of all buys by the number of buys are made on a given day.
We utilize the maximum() capacity to track down the biggest buy.
Since we’ve characterized our capacity, we can call it.
We relegate the qualities our capacity gets back to factors:
1 Normal, biggest = calculate_statistics(purchases)
We utilize the unloading language structure to get to these two qualities from our capacity.
This code allows us to get to the qualities our capacity returns in our principle program.
Since we approach these qualities outside our capacity, we print them to the control center:
print("The normal buy was ${}.".format(round(average_purchase, 2)))
print("The biggest buy was ${}.".format(round(largest_purchase, 2)))
Our code will show us the normal buy esteem and the worth of the biggest buy on the control center.
We round both of these qualities to two decimal spots utilizing the round() strategy.
We should run our program and see what occurs:
Our code returns an error message.
Solution
The error happens on the line where we attempt to unload the qualities from our capacity.
Our Error message reveals to us we’re attempting to unload values from a None worth.
This discloses to us our capacity isn’t returning the right qualities.
In the event that we investigate our capacity, we see we’ve failed to remember a bring proclamation back.
This implies our code can’t unload any qualities.
To settle this mistake, we should return the “average_purchase” and “largest_purchase” values in our capacity so we can unload them in our principle program:
def calculate_statistics(purchases):
average_purchase = int(sum(purchases)) / int(len(purchases)) largest_purchase = max(purchases) return average_purchase
Let’s run our code
The average purchase was $4.5.
The largest purchase was $8.3.
Our code tells us the average purchase was $4.50 and the largest purchase was $8.30.

Cannot unpack non-iterable int object django
This means that Django is not able to unpickle the object because it is not an iterator. Most likely, this is because you are trying to unpack a list or string into an int object. To fix this, try casting the list or string into an int object before unpacking it.
Cannot unpack non-iterable nonetype object
This means that Python is unable to understand the data you are trying to unpack. This can happen for a number of reasons, but usually, it means that there is something wrong with the data itself (for example, it might be incomplete or corrupted).
If you’re getting this error message, it’s best to try and troubleshoot the problem by checking your data for errors and fixing them if possible. If you’re not sure how to do that, you might want to reach out for help from someone more experienced with Python.
