Hi @hajsf, this is intentional. The Out[n] lines you are seeing list the return values of the expression being evaluated.

It can be confusing when the expression both writes to standard output / standard error and return some values - that's exactly what fmt.Printf does: it also returns the number of bytes written and any error. That's what you are seeing.

It should be clearer from the example below, which do not have side effects image
