    Here in this Python tutorial, we will be discussing one of the most common type errors in Python , “' int ' object is not iterable. ” It is a Python typeeror. By the end of this tutorial, you will have a complete idea about this common Python typeerror and how to debug it. As a Python programmer, you will be encountering many errors. Thus, debugging is one of the essential skills that every Python developer should have. You can not write an extensive Python program without committing any errors.

    Even professional developers also commit many errors while writing Python code. Thus, exceptional error reading and debugging skills are what separates a great Python developer from the rest.

    What is the ‘int’ object is not iterable Python Typerror?

    The error statement typeerror: ‘int’ object is not iterable is defining two messages typeerror and int object is not iterable .

    Typeerror in Python

    Typeerror is an error that generally occurs in Python when you try to call a function or use an operator of an incorrect data type. For instance, if you perform an arithmetic operation between an integer and a string, then you will receive the Python typeerror. This is so because the arithmetic operators only operate between numeric values. For example: 2 + "three"

    'int' object is not iterable

    “int object is not iterable” is an error message that tells us that we are trying to iterate over an integer object. Integer objects in Python are not iterable , and that’s why Python throws this error. For example:

    for i in 20:
        print(i) 

    The Solution to “type:error int object is not iterable”

    Now you know what is typeerror and “ int object is not iterable ,” let's proceed further. This error is one of the most common errors you will be encountering while programming in Python. In most cases, this error occurs because you forget to put the range() function inside the for loop.

    Error Scenario Example

    price_list = [20.30, 21.12, 23.78, 31.67, 77.89, 56.92, 74.92, 55.45, 66.78]
    tax_list = []
    
    for index in len(price_list):
        tax_list.append(price_list[index] + (price_list[index] *0.25))
    
    print(tax_list) 

    Output

        for index in len(price_list):
    TypeError: 'int' object is not iterable

    In the above example, the for loop is trying to iterate over len(price_list) , which has an integer value of 9. The above error “'int' object is not iterable” can be solved by wrapping the len(price_list) function with the range() function. This is shown below:

    Solution

    price_list = [20.30, 21.12, 23.78, 31.67, 77.89, 56.92, 74.92, 55.45, 66.78]
    
    tax_list = []
    
    for index in range(len(price_list)):
        tax_list.append(price_list[index] + (price_list[index] *0.25))
    
    print(tax_list)

    Output

    [25.375, 26.400000000000002, 29.725, 39.587500000000006, 97.3625, 71.15, 93.65, 69.3125, 83.475]

    Conclusion

    Typeerror is one of the most common errors in Python programs, and with every typeerror , you will also receive an error message that will tell you what exactly is wrong with your Python program. By reading the error message, you will get a brief idea of your error.

    Python also provides the line number where the error has occurred. If you are encountering the "'int' object is not iterable” error message, this probably means that there is something wrong with your for loop, and you have forgotten to put the range() method. So do it, and it will be fixed. To gain a deeper understanding of the Python language, learn from this course .
