Go, while definitely more complicated to learn initially, has the benefit of a very powerful and inclusive std lib. To me, this is one of it's largest benefits: minimal need for external libs and extra things to install.
Other than LISP maybe, but I never really learned that
Like, Hello World is probably simpler, but building even script style program seems easier and you never get stuck, because of something you don't know yet.
I can't really talk about Ruby. I learned Ruby after Perl and Smallkalk, so putting those two together was too hard.
Perl was a weird thing. It's possibly the hardest language to learn, but the fastest to program in. Kinda the opposite of Go in that sense. Everything depends a lot of context, tons of tricks, special variables and varying behavior, with default behavior you might not know you want and stuff like that. Also it requires a lot of selfdiscipline, while Go (kinda like Java) forces you to write code the way it is meant to be programmed in. In Perl you always can see whether someone actually programs in Java/C/Shell/Python/... and doesn't know the language well. In Go code one program/library feels like the other.
In which way(s)?
I've done a number of fairly complex Go projects without leaving the std library -- I can't say the same for python.
Go's http client is really easy to use; python's http client story is complicated and incomplete, and the majority of people went with the `requests` library.
