I'm trying to have an Array assign a value to two variables.
test = "hello, my,name,is,dog,how,are,you"
testsplit = test.split ","
testsplit.each do |x,y|
puts y
end
I would think that it would print
my
is
how
you
but it appears the values only get passed to x and not to y. When I run this code, y comes back empty.
Array#each will pass only one item for each iteration(thus x will be assigned a value from the array for every pass,whereas y will always be assigned to nil).Thus you need to use Enumerable#each_slice method with argument as 2.
test = "hello, my,name,is,dog,how,are,you"
testsplit = test.split ","
testsplit.each_slice(2) do |x,y|
puts y
end
# >> my
# >> is
# >> how
# >> you
You can use each_slice to take 2 elements at a time:
test = "hello, my,name,is,dog,how,are,you"
testsplit = test.split ","
testsplit.each_slice(2) do |x,y|
puts y
end
# => my, is, how, you
