>CPython is written in C, and unlike Python, C doesn’t have exceptions. So, in C, when you design a function, and you want your function to be able to indicate “there was an error”, it has to return that error as its return value This is just wrong. C doesn't feature 'error handling' as a dedicated form of branching the way many higher level languages do and you're in no way required to use return codes as an error signal. This is a case of bad API design and is entirely python's fault.
