Are you wondering why you can’t change individual items in an ‘int’ object? Confused by the “int object does not support item assignment” error message? Unravel the mystery behind ‘int’ objects and item assignments with this helpful guide!

Quick Summary

The “int’ object does not support item assignment error” is an error message that typically occurs in Python when an integer object is passed as an argument to a function that is expecting a mutable object such as a list. The problem is that, since integers are immutable, they do not support item assignment, which means that the object cannot be changed.

To fix this error, you’ll need to determine what type of object your function should be expecting. If the function is expecting a mutable object, you can use list() to convert your integer object into a mutable list which can then be modified with item assignment. If the function is expecting an immutable object, however, you’ll need to use the int() function to cast the object as an integer.

Once you’ve determined the correct type of object to use, you can pass it as an argument to the function and the error should be resolved. Alternatively, if there are more than one type of object that can be used in a particular situation, you can use the isinstance() function to make sure that the object you’re passing is of the correct type before calling the function.

Resolving ‘int’ Object Does Not Support Item Assignment Error

An ‘int’ object does not support item assignment error is one of the most common errors in Python. It occurs when a user attempts to change the value of an existing integer object. The error indicates that assignment is not allowed for an ‘int’ object. In this article, we will discuss the causes and solutions to resolving the ‘int’ object does not support item assignment error.

Causes of ‘int’ Object Does Not Support Item Assignment

The main cause of this error is the use of an immutable object (int). In Python, an int object is immutable, which means it cannot be changed after it is created. When a user attempts to modify the value of an integer object, the interpreter throws the error ‘int’ object does not support item assignment.

Ways to Resolve ‘int’ Object Does Not Support Item Assignment

To resolve the ‘int’ object does not support item assignment error, there are two options:

  • Re-create the Integer Object: When this error occurs, the user can create a new integer object with the desired value. This can be done by using the ‘int()’ function. This will replace the old integer object with the new one with the desired value.
  • Use a Mutable Object: Since int objects are immutable, a user can use another mutable object to store the required value. Python has various mutable objects like ‘list’ and ‘dictionary’ that can be used in this case. The user can create a list or dict and store the desired value in it.


In this article, we discussed the error ‘int’ object does not support item assignment and ways to resolve it. Most Python errors can be resolved by using the right approach and understanding the basics of the language. It is important to keep practising and learning the language to become an expert.

Personal Experience

Which object does not support item assignment in Python?

I came across the “int object does not support item assignment” issue when working on a project that involved manipulating data types in Python. I needed to convert a string to an integer, but when I attempted to assign that integer with a specific item, I received an error message that my ‘int’ object did not support item assignment. After some research, I discovered that ‘int’ objects are immutable and thus cannot be modified in the same way that other data types can – item assignment is part of an operation that causes the original object to be modified, so this type of data does not support it.

To find a workaround for this issue, I looked into the methods available for Python’s ‘int’ object. I found that instead of assigning specific items, I needed to work with mathematical operations. I ended up creating functions that accepted ‘int’ objects as parameters, used mathematical operations to modify the values, and returned the modified results. This allowed me to resolve the item assignment error and complete the project successfully.

Frequently Asked Questions

Which object does not support item assignment in Python?

Answer: In Python, ‘str’ objects do not support item assignment. This means that strings are immutable and cannot be changed in place. As such, attempting to assign an item to a string will cause Python to throw a TypeError.

How do you fix int objects not iterable?

The easiest way to fix int objects not iterable is to pass the variable into the range() function. This will tell Python to check the variable and if it meets the criteria, the iteration should work. As an alternative, you can also use a for-loop with an if-statement to loop through the variable type. Lastly, you can always try converting the variable to a list or tuple to check if it becomes iterable.

How do I fix int object is not Subscriptable error?

To fix the ‘int object is not Subscriptable error’, you need to convert the integer to an iterable data type, for example, a string. This means changing the integer to a string, list or dictionary that Python can process and loop through. Once converted, the code should run without any issues. It is important to check data types when coding in Python to avoid any errors.

What does object does not support item assignment mean?

Object does not support item assignment means that attempting to modify an object, like a string which is immutable in Python, results in an error. This error occurs when someone attempts to change a single character in a string, as strings are not mutable and cannot be modified. An item assignment is any change to the object that would affect its value.

How do I fix str object does not support item assignment in Python?

To fix the “str object does not support item assignment” error in Python, you need to create a new string based on the contents of the old one. This can be done by using the string methods such as .replace(), .join(), .split(), .****(), .lstrip(), and .rstrip() to create the new string. Once the new string is created, you can directly assign the values you need.

Why does string not support item assignment?

Strings are immutable in Python, meaning they can’t be modified. Therefore, attempting to assign a value to a particular item in a string will throw a TypeError as strings do not support item assignment. For example, trying to reassign a character at an index of a string will throw the TypeError – “str” object does not support item assignment.

Does string support item assignment?

No, strings do not support item assignment. Strings are immutable data types, meaning the contents of a string can not be changed once it has been assigned. As such, item assignment, which requires an object to be modified, is not supported.

Does sets support item assignment?

No, sets do not support item assignment. It is not supported in functions, modules, or classes. This behavior is an inherent limitation of sets and cannot be changed.

How do you fix set objects are not Subscriptable?

To fix a “set object is not subscriptable” error, convert the unordered set to an ordered list or tuple before attempting to access it. Alternatively, you can get rid of any attempts to index or slice the set. Either of these solutions can help you fix the error.

Final Thoughts

The TypeError: ‘int’ object does not support item assignment error is one of many types of errors that can appear while coding in Python 3. Fortunately, this specific error type is relatively straightforward to diagnose and fix, with different measures to take based on the specific code or context in which the error is occurring. Fixing this type of runtime error requires the programmer to look closely at the code and how the data values are being handled, as the error is especially likely to appear when list or dictionary elements are being assigned a value in an incorrect manner. Thus, identifying the source of the issue and fixing it accordingly can allow the programmer to continue coding with fewer interruptions.
