Typeerror: type object is not subscriptable ( Steps to Fix)

Typeerror_ type object is not subscriptable Steps to Fix

Typeerror: type object is not subscriptable error occurs while accessing type object with index. Actually only those python objects which implements __getitems__() function are subscriptable. In this article, we will first see the root cause for this error. We will also explore how practically we can check which object is subscriptable and which is not. At last but not least, we will see some real scenarios where we get this error. So let’s start the journey.

 

Typeerror: type object is not subscriptable ( Fundamental Cause) –

The root cause for this type object is not subscriptable python error is invoking type object by indexing. Let’s understand with some practical scenarios.

var_list=[1,2,3]
var=type(var_list)
var[0]
typeerror type object is not subscriptable root cause
typeerror type object is not subscriptable root cause

Here var is a type python object. In the place of same, the list is python subscriptable object. Hence we can invoke it via index. Moreover, Here is the implementation –

var_list=[1,2,3]
var=type(var_list)
var_list[0]

Typeerror: type object is not subscriptable ( Solution ) –

The best way to fix this error is using correct object for indexing. Let’s understand with one example.

type object is not subscriptable python example
type object is not subscriptable python example

 

The fix is calling var[0] in the place of var_type[0] . Here ‘var’ is the correct object. It is a ‘str’ type object which is subscriptible python object.

 

How to check python object is subscriptable ?

Most importantly, As I explained clearly, Only those object which contains __getitems__() method in its object ( blueprint of its class) is subscriptible. Let’s see any subscriptible object and its internal method-

print(dir(var))

The output is –

['__add__', '__class__', '__contains__', '__delattr__', '__dir__',
 '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__', '__getitem__', '__getnewargs__',
 '__gt__', '__hash__', '__init__', '__init_subclass__', '__iter__', '__le__', '__len__', '__lt__', 
'__mod__', '__mul__', '__ne__', '__new__', '__reduce__', '__reduce_ex__', '__repr__', '__rmod__', 
'__rmul__', '__setattr__', '__sizeof__', '__str__', '__subclasshook__', 'capitalize', 'casefold',
 'center', 'count', 'encode', 'endswith', 'expandtabs', 'find', 'format', 'format_map', 'index', 
'isalnum', 'isalpha', 'isascii', 'isdecimal', 'isdigit', 'isidentifier', 'islower', 'isnumeric', 
'isprintable', 'isspace', 'istitle', 'isupper', 'join', 'ljust', 'lower', 'lstrip', 'maketrans',
 'partition', 'replace', 'rfind', 'rindex', 'rjust', 'rpartition', 'rsplit', 'rstrip', 'split', 
'splitlines', 'startswith', 'strip', 'swapcase', 'title', 'translate', 'upper', 'zfill']

Firstly, As the internal method __getitem__() is available in the implementation of the object of var( list) hence it is subscriptible and that is why we are not getting any error while invoking the object with indexes. Hope this article is helpful for your doubt.
