Discussion on: Introduction to YAML

View post

Thanks for all the tips and tricks. I like using YAML for configurations.

PS: YAML has some default casting one should be aware of:

In [4]: yaml.load('yes') # 'Yes' and 'No' become boolean
Out[4]: True

In [5]: yaml.load('1_000_000')
Out[5]: 1000000

Thank you! According to the YAML 1.2 specification document 'yes' and 'no' are no longer interpreted as boolean.

We have removed unique implicit typing rules and have updated these rules to align them with JSON's productions. In this version of YAML, boolean values may be serialized as “true” or “false”;

You can use !!bool to parse them, though.
