extra output?

[PhilipLutley]

This is probably down to my lack of understanding notebooks..

Is there any way I can get rid of the extra output cell? It's giving me my output plus an extra character count cell (I think).

The output cell shows the values returned by the last expression - in your case, fmt.Println(...) returns two values:

• the number of printed characters
• any error occurred while printing (nil in your case)

This is a general feature, and useful in many cases - see this screenshot for an example

If you want to suppress the values returned by the last expression, you can assign them to _
or wrap the expression inside { ... } to convert it to a statement (Go statements do not return values) - for example
