3> lists:foreach( fun(X)->X*X end, [1,2,3]). >
produces no output because the purpose of foreach is to generate side-effects. However,
4> lists:foreach( fun(X)->io:format("~w ",[X]) end, [1,2,3,4]). 1 2 3 4
does work, because io:format() is a side effect function.
sequence of numbersEdit
lists:seq(1,100) is like range(1,101) in python.
5> lists:seq(1,10). [1,2,3,4,5,6,7,8,9,10]
lists:sort( A ) is what you think.
