在循环内创建多个对象

Question

以下代码会覆盖@journey_lines 10次，只留下最后一次保存为数组的旅程。我想为每个旅程（1到10）创建一个新的数组对象。

# Save text file to string
data = File.read("workdata.txt")

# Split string into blocks of text relevant to each journey
journeys = data.split(/\n\s\n/)

# Store the amount of journeys as a variable called journeys_size
journeys_size = journeys.length

# Split each journey into lines and save to an array called "journey_lines"
journeys[1..10].each { |i| @journey_lines = i.split(/\n/) }

# Inspect journey_lines 
p @journey_lines

有没有办法将变量插入迭代值？有点像...

journeys[1..#journeys.size].each { |i| @journey_lines[1..#journeys_size] = i.split(/\n/) }

或者更好的方式一起完成这一切。我已经尝试过一段时间了。请帮忙！

您应该使用map方法

@journey_lines = journey.map {|item| item.split(/\n/) }
