foo = [3, 6, 3]
for a in foo:
print a
我如何在 ruby 中做到这一点？
最佳答案
list = %w( a b c )
# there's a for statement but nobody likes it :P
for item in list
puts item
end
# so you use the each method with a block instead
# one-liner block
list.each { |item| puts item }
# multi-line block
list.each do |item|
puts item
end
