YAML序列样式

要理解序列样式，理解集合很重要。集合和序列样式的概念并行工作。YAML中的集合以适当的序列样式表示。如果要引用正确的标签排序，请始终参考集合。YAML中的集合由数组中表示的从零开始的连续整数编制索引。序列样式的重点始于集合。

例

让我们将宇宙中行星的数量视为可以作为集合创建的序列。以下代码显示如何表示Universe中行星的序列样式

# Ordered sequence of nodes in YAML STRUCTURE
Block style: !!seq
- Mercury   # Rotates - no light/dark sides.
- Venus     # Deadliest. Aptly named.
- Earth     # Mostly dirt.
- Mars      # Seems empty.
- Jupiter   # The king.
- Saturn    # Pretty.
- Uranus    # Where the sun hardly shines.
- Neptune   # Boring. No rings.
- Pluto     # You call this a planet?
Flow style: !!seq [ Mercury, Venus, Earth, Mars,      # Rocks
                    Jupiter, Saturn, Uranus, Neptune, # Gas
                    Pluto ]                           # Overrated

然后，您可以看到JSON格式的有序序列的以下输出

{
   "Flow style": [
      "Mercury",
      "Venus",
      "Earth",
      "Mars",
      "Jupiter",
      "Saturn",
      "Uranus",
      "Neptune",
      "Pluto"
   ],

   "Block style": [
      "Mercury",
      "Venus",
      "Earth",
      "Mars",
      "Jupiter",
      "Saturn",
      "Uranus",
      "Neptune",
      "Pluto"
   ]
}
