pyyaml

First, a disclaimer: I'm not too familiar with YAML. I'm trying to parse a YAML doc into Key Value Pairs (don't worry about how I'm doing it. I've got that bit handled) My file used to look something like: world: people: name:Suzy address:chez-bob Then, someone went and changed it. world: people: name:!$uzy address:chez-bob And I get this parse error: yaml.constructor.ConstructorError: could not determine a constructor for the tag '!$uzy' What does this even mean? How would I go about getting it to just interpret !$ as just two characters? I just want a dictionary of string keys and values!

I have a yaml file that looks like this: # The following key opens a door key: value Is there a way I can load and dump this data while maintaining the comment? phihag PyYAML throws away comments at a very low level (in Scanner.scan_to_next_token ). While you could adapt or extend it to handle comments in its whole stack, this would be a major modification. Dump ing (=emitting) comments seems to be easier and was discussed in ticket 114 on the old PyYAML bug tracker. If you are using block structured YAML, you can use the python package¹ ruamel.yaml which is a derivative of PyYAML and supports

I'm using yaml.dump to output a dict. It prints out each item in alphabetical order based on the key. >>> d = {"z":0,"y":0,"x":0} >>> yaml.dump( d, default_flow_style=False ) 'x: 0\ny: 0\nz: 0\n' Is there a way to control the order of the key/value pairs? In my particular use case, printing in reverse would (coincidentally) be good enough. For completeness though, I'm looking for an answer that shows how to control the order more precisely. I've looked at using collections.OrderedDict but PyYAML doesn't (seem to) support it. I've also looked at subclassing yaml.Dumper , but I haven't been able

I've got an object with a short string attribute, and a long multi-line string attribute. I want to write the short string as a YAML quoted scalar, and the multi-line string as a literal scalar: my_obj.short = "Hello" my_obj.long = "Line1\nLine2\nLine3" I'd like the YAML to look like this: short: "Hello" long: | Line1 Line2 Line3 How can I instruct PyYAML to do this? If I call yaml.dump(my_obj) , it produces a dict-like output: {long: 'line1 line2 line3 ', short: Hello} (Not sure why long is double-spaced like that...) Can I dictate to PyYAML how to treat my attributes? I'd like to affect both

I have a Python program that uses YAML. I attempted to install it on a new server using pip install yaml and it returns the following: $ sudo pip install yaml Downloading/unpacking yaml Could not find any downloads that satisfy the requirement yaml No distributions at all found for yaml Storing complete log in /home/pa/.pip/pip.log How do I install the yaml package for Python? I'm running Python 2.7. (OS: Debian Wheezy) Bonlenfum You could try the search feature in pip, $ pip search yaml which looks for packages in PyPI with yaml in the short description. That reveals various packages,
