Usage of 'and' in Python -

this question has answer here: python , / or operators return value 4 answers i'm maintaining large codebase , found looks in python code: ... foo = bar(a, b, c) , foo return foo ... where foo assigned boolean, , declared first time here. mean/what purpose serve/what's going on here? python short circuit evaluation c does. this means in "and" case, right side of and evaluated if left side true. so code equivalent to: x = bar(a, b, c) if x: foo = foo else: foo = x return foo with distinction of course, variable x not used (since not needed). the important fact note here is, example if foo set "stringval" , bar(a,b,c) returns can interpreted true, "stringval" returned. unlike in other languages, boolean expression can have non-boolean result.

java 8 - What are the differences between an aggregate operation and a method? -

.......... well, let me tell made mistakes: foreach() refering not aggregate operation method iteable. i've changed title of question , content. my interest know if aggregate operation implemented default , can find implementation. if want dig jdk sources can download them here @jbkm suggest. if have oracle jdk installed, there should src.zip file in installation folder contains public sources. alternatively can check openjdk sources online, example, on grepcode . can see, implementation of foreach iterable quite simple: default void foreach(consumer<? super t> action) { objects.requirenonnull(action); (t t : this) { action.accept(t); } } if you're asking implementation of foreach in stream api, it's more tricky thing should evaluate previous pipeline steps , perform operation in parallel parallel streams. can start investigation examining referencepipeline class stream implementation in openjdk.
