我有一个包含以下信息的 txt 文件：

- name: python-3.8.9-amd64.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd64.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6\n
- name: python-3.8.9-amd645.exe\n
  link: https://www.python.org/ftp/python/3.8.9/python-3.8.9-amd645.exe\n
  sha256summ: e15bc52914b6daee9630360bfe3708ee646d4e4ce34bf5368066213009af70a6

比如重复两次，可以是无限的，我需要name: link: sha256sum:在循环中获取一个包含better的列表，为了进一步处理列表，我不需要保存它

您需要更改 yaml 文件中的值：

singleuser:
  image:
    name: hub/k8s-network-tools
    tag: "1.2.0"

写了这个脚本：

#!/usr/bin/env python

import yaml
import argparse

parser = argparse.ArgumentParser(description='Скрипт')
parser.add_argument('key', type=str, help='key')
parser.add_argument('value', type=str, help='value')
args = parser.parse_args()

with open("values.yaml") as f:
    try:
        list_doc = yaml.load(f)
        
        for arr in list_doc:
            arr[args.key] = args.value

        with open("values.yaml", "w") as f:
            yaml.dump(list_doc, f)

    except yaml.YAMLError as exc:
        print(exc)

我收到一个错误：

user@myPC test % python change_values.py "singleuser.image.tag" "1.2.1"
change_values.py:13: YAMLLoadWarning: calling yaml.load() without Loader=... is deprecated, as the default Loader is unsafe. Please read https://msg.pyyaml.org/load for full details.
  list_doc = yaml.load(f)
Traceback (most recent call last):
  File "change_values.py", line 16, in <module>
    arr[args.key] = args.value
TypeError: 'str' object does not support item assignment
user@myPC test %

告诉我这里出了什么问题，或者如何正确地做

我正在尝试创建 yaml

import sys
from ruamel.yaml import YAML

class Entry:
    yaml_tag = '!<!entry>'

    def __init__(self, value, style=None):
        self.value = value
        self.style = style

    @classmethod
    def to_yaml(cls, representer, node):
        return representer.represent_mapping(cls.yaml_tag, node.value, node.style)

    @classmethod
    def from_yaml(cls, constructor, node):
        return cls(node.value, node.style)

data = {
    'steps': [
        Entry({
            'id': 'Entry-1',
            'actions': [],
        })
    ],
}

yaml = YAML(typ='rt')
yaml.register_class(Entry)
yaml.dump(data, sys.stdout)

但在输出中，!<!entry>我得到了!%3C%21entry%3E.

steps:
- !%3C%21entry%3E
  id: Entry-1
  actions: []
