That's true but also C's error reporting differs greatly between libraries. Each library has a learning curve in how it wants it's errors checked. From the top of my head, 10 years after writing any C code there is check against NULL - guess the error, check against minus values - lookup minus values in a table, check against 0 - call method to get error string and many more.
Go standardises this in a super clean way. Every method that can error will return an error. If you try to write a method that calls methods that can error and you don't return an error then you will be extremely aware of that. After a few days of Go it will be physically painful to write code that eats errors.
So what Go did was to take the return parameter style of error reporting, mix in multiple return values to make that not suck and then optimize towards the local maxima of programming comfort within this paradigm.
The result - as anyone who has been writing go for a few months can tell you - is something that works incredibly well. I'd say it works better then exceptions style all but that may be my personal preference.
I don't doubt that Go is usable and reflects an attempt to rationalize C's (non) conventions, which is a goal I appreciate. but it certainly isn't false for Python that 'the result - as anyone who has been writing [Python] for a few months can tell you - is something that works incredibly well.'
