>>60With a good library or bindings to one you can express in 3 lines something which would take 3000 lines otherwise. So libraries are a quality of the language. They make much more programs expressible in the practically-finite amount of time.
And it isn't the libraries that let Python win over Perl and C, but libraries let it win over e.g. Scheme and Lua.
Perl loses to Python on point 1 (hard-to-read code and lack of OOP which makes life easier for many)
C loses to Python on point 1 (manual memory management means lots of unobvious mistakes and dealing with pointers is hard) but wins on point 2 but there are areas where point 2 is very elastic.
Scheme and Lua lose to Python on point 3 (no comparable libraries).
Ruby is pretty much a match to Python except a moderate weakness on point 3 (no SciPy or NumPy, for instance).
