无法将 yaml 文件解析为 python

Question

I am trying to parse data from a simple YAML file into python however running the program generates an error.

File.py

#!/usr/bin/env python3

import yaml

with open ('xyz.yml', 'r') as handle:

try:
    print("File opened")
    data = yaml.full_load(handle)
    print("data loaded")
    print(data)
except yaml.YAMLError as error:
    print(error)

YAML file contains as below.

xyz.yml

---

name: nick # YAML allows comments things: -chair -table

• sofa: color: gray age: 2

However, running the program

➜ PYTHON python3 file.py File opened mapping values are not allowed here in "xyz.yml", line 9, column 9

Anything wrong with syntax or code? The same data works with JSON. I have tried the same code with JSON Data, of course with JSON structure data and loading the JSON library and necessary JSON calls in the python program

Answer 1

The problem here is with your YAML file I believe, it should've been:

name: nick # YAML allows comments
things:
  - chair
  - table
  - sofa:
      color: gray
      age: 2

YAML depends a lot on indentation so keep that in mind.
