[Yaml-core] how to write python structures in YAML

[Clark C. E. <cc...@cl...>]

I was asked a question off-list about how YAML 'escaping'
worked, especially in the context of Python.  I guess
the best way to answer is with running code...

---------------------------------------------
#!/usr/local/bin/python
a = {
   "p1": {"- foo":"goo","- bar":"baz"},
   "p2": [  "foo: goo",   "bar: baz"],
   "p3": [ {"foo":"goo"},{"bar":"baz"}]
}
import syck
b = syck.load("""\
--- {
  p1: {'- foo': goo, '- bar': baz},
  p2: ['foo: goo',   'bar: baz'] ,
  p3: [{foo: goo}, {bar: baz}] }
""")
c = syck.load("""\
---
  p1: {'- foo': goo, '- bar': baz}
  p2: ['foo: goo',   'bar: baz']
  p3: [{foo: goo}, {bar: baz}]
""")
d = syck.load("""\
---
  p1:
    '- foo': goo
    '- bar': baz
  p2:
    - 'foo: goo'
    - 'bar: baz'
  p3:
    - foo: goo
    - bar: baz
""") 
print "a == b",  str(a) == str(b)
print "a == c",  str(a) == str(c)
print "a == d",  str(a) == str(d)
