How to Fix “TypeError: Object of Type ‘Int’ Has No Len” in Python?

Are you trying to find the length of an integer value 🤔 and getting the “TypeError: object of type int has no len” error when developing with Python?

In Python, we can only find the length of iterable objects such as lists, strings, tuples, etc. but not individual integer values because we can iterate through iterable objects, whereas an individual integer value isn’t iterable. So we cannot find the length of an integer. Otherwise, we’ll get the “TypeError: object of type ‘int’ has no len” error in Python.

In this article, we’ll discuss what is the “TypeError: object of type ‘int’ has no len” error in Python, why it occurs, and how to fix it. So let deep down into the topic

 

 

What is the “TypeError: Object of Type Int Has No Len” Error in Python?

Do you need clarification about what causes the TypeError: object of Type ‘int’ has no len in Python? But before discussing the solution, first, let’s see a demonstration of the error.

 

Code 

x = 4

print(f"The Type of {x} is {type(x)}" )

len(x)

 

Output

 TypeError Object of Type 'Int' Has no Len

 

As you can see in the above example, the type of x is int; it is not iterable to clearly understand it; let’s see does an integer value support len() function or not.

 

Code

x = 4

print(f"The Type of {x} is {type(x)}" )

print(dir(x))

 

Output

integer value does not support len function

 

As you can see in the above code example, there isn’t any len() for integer objects.

 

 

How to Fix the “TypeError: Object of  Type Integer Has No Len” Error in Python?

To fix the TypeError: object of Type ‘int’ has no len in Python, we can convert the integer value into a string to find its length. 

 

Code

x = 4
print("Dir int")

print(f"The Type of {x} is {type(x)} \n" )

print(dir(x))


# type casting int to string 
str_x = str(x) 


print("\n\nDir string")

print(f"The Type of {str_x} is {type(str_x)}")

print(f"The length of {str_x} is {len(str_x)}\n") 

print(dir(str_x))

 

Output

TypeError Object of Type 'Int' Has no Len img 1

 

You can see 👀 in the above code example, the integer value isn’t supporting the int(), but when we type cast x to a string, it supports len().

Let’s use the len() function with some iterables like lists, tuples, and strings:

 

Code

# create list

billionaires = ["Elon", "Mark", "Jeff", "Bill"]

print(f"This length of {billionaires} is {len(billionaires)}\n")



# lets loop thorught the iterable 'list'

for i in range(len(billionaires)):

    print(f"{i}) {billionaires[i]}")

 

Output

This lenght of ['Elon', 'Mark', 'Jeff', 'Bill'] is 4

0) Elon

1) Mark

2) Jeff

3) Bill

 

As we know that lists are iterable objects, we can find their length using the len() function and loop through it to access individual elements of it, as shown in the above example. Similarly, for any iterable, we can iterate by using a for loop.

 

 

Use Exception Handling to Fix The “TypeError Object of Type Int Has No Len” Error in Python

Exception handling is a proactive strategy for error and exception handling in computer programming that helps in handling the errors before they crash the computer program. It is one of the most useful techniques in computer programming; let’s see how it assists us in handling the TypeError: the object of Type ‘int’ has no len before crashing our program.

 

Code

try:

    x = 4

    len(x)


except TypeError:

    # customzie the error message

    print('You cannot find the length of an integer using len()')


print("The good thing is the program isn't crashed yet\nisn’t this amazing?")

Output

You cannot find the lenght of an integer using len()

The good thing is the program isn't crashed yet

isn't this amazing?

 

As you can see in the above ☝️ code example, we’ve demonstrated how exception handling saves your program from crashing but instead gives you warnings and alerts that the program has some error in the form of a customized message.

 

 

Conclusion

To summarize the article on how to Fix the TypeError: the object of Type ‘int’ has no len in Python, we’ve discussed why it occurs and how to get rid of it. Furthermore, we’ve seen how to typecast an integer to a string to find its length using len() function.

In addition, we’ve discussed how to find the length of iterable like lists to loop through it, and at the end, we’ve used exception handling to handle the exceptions before crashing our Python program.
