In Golang, the WithMessage() method allows you to annotate errors with an additional message. Often, error values by themselves don’t give enough context to be useful in debugging. Take, for example, Golang’s basic error handling technique: In Golang, errors are treated as values, so err contains the error value. In this situation, a developer could make use of the error package to add context to the code along with the failure path without destroying the original value of the error.

The PHP strpos($haystack, $needle, $offset) function is used to find the numeric position of the first occurrence of a substring in a string. The haystack parameter is the string to search in, and needle is the substring being searched for. The E_WARNING: strpos(): Empty needle warning is issued if the needle substring is empty when calling the strpos() function.

In Golang, wrapping errors means adding more contextual information to the error which has been returned. For example, the additional information could be the type of error, the cause of the error, or the name of the function where the error is raised. Wrapping is very useful for debugging since you can precisely and quickly locate the source of the problem.

The Python TypeError: NoneType Object Is Not Iterable is an exception that occurs when trying to iterate over a None value. Since in Python, only objects with a value can be iterated over, iterating over a None object raises the TypeError: NoneType Object Is Not Iterable exception.
