I will argue that learning curves are similar with Ruby, SmallTalk, ML, and Scheme to Python. Logo is the original teaching language, and I think is similarly easy. It's my belief that people exaggerate the learning curve of Haskell, but whatever, I'll grant you that. If your criteria for readability is "English-like" I think you're missing a lot of what makes Python so readable in the first place. It is not very English-like at all. Compare to say COBOL, which actually had English-like readability as a design goal and was by all accounts an unmitigated disaster. AppleScript has a similar reputation for being a "read-only" language because of how difficult it is to pick up from reading it. What makes Python readable is having a small number of concise syntax constructs that compose into complex programs, the same things that make functional code readable. The presence of words vs operators is probably important, and Haskell tends towards the latter, but the ML family doesn't, and Lisps are plenty readable if you keep them simple. There's a reason that SICP and HTDP use Scheme, the latter using a gradually larger subset to make it less intimidating.
