You get the 'builtin_function_or_method' object is not subscriptable error when you mistakenly use square brackets [] on a function without calling it. To fix it, add parentheses () to call the function first.
Example: Use list(range(5))[0] instead of list[0].
To fix the 'builtin_function_or_method' object is not subscriptable error in Python, check if you're using parentheses () where needed. This error happens when you try to use square brackets [] on a function without calling it. For example, use list()[0] instead of list[0]. Always call the function before attempting to access elements from its result.
