Example from Using YAML with Python
Original YAML file contains this
# tree format
treeroot:
branch1:
name: Node 1
branch1-1:
name: Node 1-1
branch2:
name: Node 2
branch2-1:
name: Node 2-1
After loading the content from the file using yaml.load()
, and dump it into a new YAML file, I get this instead:
# tree format
treeroot:
branch1:
branch1-1: {name:Node 1-1}
name: Node 1
branch2:
branch2-1: {name: Node 2-1}
name: Node 2
What is the proper way of building up a YAML file straight from pure python? I don't want to write string myself. I want to build the dictionary and list.
Partial...
dataMap = {'treeroot':
{'branch2':
{'branch1-1':
{'name': 'Node 1-1'}, # should be its own level
'name': 'Node 1'
}
}
}
OKay. I just double checked the documentation. We need this at the end of the yaml.dump(data, optional_args)
The fix is this
yaml.dump(dataMap, f, default_flow_style=False)
where dataMap is the source yaml.load()
and f is the file to be written to.
