Typeerror object of type int has no len

The typeerror object of type int has no len is an error message that we may encounter in Python.

Learn about and understand this error through this article.

As we repeatedly say, understanding the error is the best first step toward fixing it.

Moving on, let us start understanding this error.

What is typeerror object of type int has no len?

As we have specified in our first sentence above, the “typeerror object of type int has no len” is an error message in Python.

The specified error occurs when we attempt to call a len() function on an integer.

This happens because we can’t get an integer’s length, as it is unsupported in Python.

What is a len() function?

A len() function is one of Python’s built-in functions.

This function is used to determine the length of an object.

You can use this for the three (3) built-in sequences in Python.

They are:

✅ String, list, and tuple

Sample usage of the len() function with the three (3) built-in sequences shown above.

Sample 1 (string):

s_str = "Hi! IT source coders!"
s_len = len(s_str)
print(s_len)

Output:

21

Sample 2 (list):

s_list = ["Math", "English", "Filipino", "Science"]
s_len = len(s_list)
print(s_len)

Output:

4

Sample 3 (tuple):

s_tuple = (-20.2302, 12.2345, -123.87690)
s_len = len(s_tuple)
print(s_len)

Output:

3

Back to the issue, here is a sample code that causes this error:

s_int = 2023
s_int_len = len(s_int)
print(s_int_len)

Error:

Traceback (most recent call last):
  File "C:\Users\path\PyProjects\sProject\main.py", line 2, in <module>
    s_int_len = len(s_int)
                ^^^^^^^^^^
TypeError: object of type 'int' has no len()

Now that we have understood this error, let us proceed to our solution.

Typeerror object of type int has no len – SOLUTION

To fix typeerror object of type int has no len, you have to make sure that you are not calling the len() function on an integer.

However, if you are using an integer and you can’t change it, you can convert it into a string.

Example code:

s_int = 2023
s_str = str(s_int)
s_str_len = len(s_str)
print(s_str_len)

Output:

4

Alternative solution

Aside from the solution above, there is an alternative solution to fix this error.

✅ Use integer-compatible functions.

You can use math functions or bitwise operations.

What you choose depends on what you are trying to achieve.

Conclusion

In conclusion, the “typeerror object of type int has no len” occurs when you call the len() function on an integer.

You can solve this error by converting the integer into a string.

By following the guide above, you will surely solve this error quickly.

That is all for this tutorial, IT source coders!

We hope you have learned a lot from this. Have fun coding!
