How to Fix “Function Object is Not Subscriptable” in Python

"Subscriptable" refers to objects like lists, arrays, or dictionaries in Python that allow access to their elements using square brackets, whereas functions are not inherently subscriptable, resulting in a "function object is not subscriptable" error if treated as such. This error occurs when square brackets are mistakenly used directly on a function rather than on the function's return value, which can be accessed by calling the function first. To resolve this, one should ensure the function returns a subscriptable object and correctly call the function before attempting to access any elements. Furthermore, tracking and managing errors in code can be streamlined with tools like Rollbar, which provides real-time error monitoring and helps developers confidently handle exceptions in their Python applications.
