TypeError: argument of type ‘NoneType’ is not iterable

The python error TypeError: argument of type ‘NoneType’ is not iterable occurs when the membership operators check a value in a NoneType variable. The python membership operator (in, not in) checks a value in an iterable objects such as tuple, list, dict, set etc. If the iterable object is passed

TypeError: object of type ‘bool’ has no len()

The python error TypeError: object of type ‘bool’ has no len() occurs when trying to find the length of an object that returns boolean. The python length function can not be used in objects of a boolean type. The Length function is used for objects that hold many objects. Therefore,

TypeError: object of type ‘float’ has no len()

The python error TypeError: object of type ‘float’ has no len() occurs while attempting to find the length of an object that returns ‘float’. The python length function can not be used in the ‘float’ type objects. The Length function is used for objects that store multiple objects. Hence, the

TypeError: object of type ‘builtin_function_or_method’ has no len()

The python error TypeError: object of type ‘builtin_function_or_method’ has no len() occurs while attempting to find the length of an object that returns a build in function or a method. The python variables can have a reference of a build in function or a method. If a python variable refers

TypeError: object of type ‘type’ has no len()

The python error TypeError: object of type ‘type’ has no len() occurs while attempting to find the length of an object that returns ‘type’. The python variables can store object data types. If a python variable refers a data type, it can’t be used in length function. The Length function

TypeError: object of type ‘NoneType’ has no len()

The TypeError: object of type ‘NoneType’ has no len() error occurs while attempting to find the length of an object that returns ‘None’. The python object whose data type is NoneType can’t be used in length function. The Length function is used for data structures that store multiple objects. The

IndexError: tuple index out of range

The IndexError: tuple index out of range error occurs when you access an item that does not exist in the tuple. The python error IndexError: tuple index out of range occurs when an item in a tuple is accessed using invalid index. The access index should be within the tuple

TypeError: unhashable type: ‘set’

The python error TypeError: unhashable type: ‘set’ happens when a set is added to another set or used as a key in a dictionary. The set is an unhashable object in python. The unhashable objects are not allowed in set or dictionary key. The dictionary or set hashes the object

TypeError: unhashable type: ‘dict’

The TypeError: unhashable type: ‘dict’ error happens when you try to use a dict as a hash argument when adding as a key in another dict or in a set. The dict is an unhashable object that you’ve been trying to hash. The python unhashable type dict is not allowed

AttributeError: ‘str’ object has no attribute ‘append’

The AttributeError: ‘str’ object has no attribute ‘append’ error occurs when the append() attribute is called in the str object instead of the concatenation operator. The str object does not have the attribute append(). That’s when the error AttributeError: ‘str’ object has no attribute ‘append’ has happened. The python string does

ImportError: cannot import name

The python ImportError: cannot import name error occurs when the import class is inaccessible or the imported class in circular dependence. The import keyword is used to load class and function. The keyword from is used to load the module. For any reason, if the import class is not available

TypeError: ‘module’ object is not callable

The TypeError: ‘module’ object is not callable error occurs when python is confused between the class object and module. Python attempts to invoke a module as an instance of a class or as a function. This TypeError: ‘module’ object is not callable error occurs when class and module have the

TypeError: unhashable type: ‘list’

The TypeError: unhashable type: ‘list’ error occurs when you try to add a list as a key in a dictionary or as an item in a python Set. A hashable object is used as a key in the dictionary. The list is an unhashable type object that you’ve been trying

IndexError: list index out of range

The python error IndexError: list index out of range occurs when an incorrect indices is used to access a list element. The index value should not be out of range. Otherwise IndexError will be thrown. For example, if you try to access indices that are outside the index range in

TypeError: object of type ‘int’ has no len()

In python, the error “TypeError: object of type ‘int’ has no len()” occurs when the length function is invoked on objects that does not support the length function. The length function is supported by iterable objects such as list, tuple, dictionary and string. The length function is used to find
