Do you encounter the following error message?<\/p>\n

TypeError: NoneType is not subscriptable<\/code><\/pre>\n
You’re not alone! This short tutorial will show you why this error occurs, how to fix it, and how to never make the same mistake again. <\/p>\n
So, let’s get started!<\/p>\n
Summary<\/h2>\n
Python raises the TypeError: NoneType is not subscriptable<\/code> if you try to index x[i]<\/code> or slice x[i:j]<\/code> a None<\/code> value. The None<\/code> type is not indexable, i.e., it doesn’t define the __getitem__()<\/a><\/code> method. You can fix it by removing the indexing or slicing call, or defining the __getitem__<\/code> method.<\/p>\n
Example<\/h2>\n
\n
\"<\/figure>\n<\/div>\n
The following minimal example that leads to the error:<\/p>\n
x = None\nprint(x[0])\n# TypeError: 'NoneType' object is not subscriptable<\/pre>\n
You set the variable<\/code> to the value None<\/code>. The value None<\/code> is not a container object, it doesn’t contain <\/em>other objects. So, the code really doesn’t make any sense—which result do you expect from the indexing operation?<\/p>\n
Exercise<\/strong>: Before I show you how to fix it, try to resolve the error yourself in the following interactive shell:<\/em><\/p>\n
