Practical Uses of YAML
As noted earlier, YAML is mostly praised for its readability, which makes it perfect for storing all kinds of configuration data in a human-readable format. It became especially popular among DevOps engineers, who’ve built automation tools around it. A few examples of such tools includ... | |

ros_yaml/pythonyaml_169.txt | When you decide to use the !!python/object tag in YAML, then the library calls .__new__() without any arguments and never calls .__init__(). Instead, it directly manipulates the .__dict__ attribute of your newly created object, which can have some undesired effects: | |

ros_yaml/pythonyaml_122.txt | Note: Before version 6.0 of the PyYAML library, the default way of parsing YAML documents had always been the yaml.load() function, which defaulted to using an unsafe parser.

ros_yaml/pythonyaml_34.txt | In Python, performance when working with these data formats will vary, and it’ll be highly sensitive to the implementation you choose. A pure Python implementation will always lose to a compiled C library. In addition to this, using different XML processing models—(DOM, SAX, or StAX)—will also impact performance. | |
ros_yaml/yamlinpython_7.txt | Some of the widely used data serialization languages include YAML, XML, and JSON. While XML and JSON are used for data transfer between applications, YAML is often used to define the configuration for applications. | |

ros_yaml/pythonyaml_117.txt | On the other hand, if type safety is your main concern or you’d like to validate YAML documents against a schema, then have a look at StrictYAML, which intentionally restricts the YAML specification by disregarding its most risky features. Just keep in mind that it won’t run as quickly as the other two libraries. | |
ros_yaml/pythonyaml_62.txt | Note: The PyYAML library used in this tutorial is based on the older YAML 1.1 specification, which supports base-60 numbers through the colon (:) notation. This means that a literal like 59:59 gets interpreted as an integer value of 3,599 because 59 × 601 + 59 × 600 adds up to it. | |

ros_yaml/pythonyaml_35.txt | Implementations aside, YAML’s versatile, liberal, and complex syntax makes it by far the slowest to parse and serialize.
