删除字典对象- python周围的双引号

Question

我有一个字典，我用它来填充每个键的YAML配置文件。

{'id': ['HP:000111'], 'id1': ['HP:000111'], 'id2': ['HP:0001111', 'HP:0001123'])}

使用ruamel.yaml

将键:值对插入YAML模板的代码

import ruamel.yaml
import sys
yaml = ruamel.yaml.YAML()
with open('yaml.yml') as fp:
data = yaml.load(fp)
for k in start.keys():
data['analysis']['hpoIds'] = start.get(key)
with open(f"path/yaml-{k}.yml","w+") as f:
yaml.dump(data, sys.stdout)

这是我得到的输出

analysis:
# hg19 or hg38 - ensure that the application has been configured to run the specified assembly otherwise it will halt.
genomeAssembly: hg38
vcf:
ped:
proband:
hpoIds: "['HP:000111','HP:000112','HP:000113']"

但这就是我需要的

hpoIds: ['HP:000111','HP:000112','HP:000113']

我试过使用字符串工具，如strip, replace，但没有

ast.literal_eval.

输出

hpoIds:
- HP:000111
- HP:000112
- HP:000113

repr

输出

hpoIds: ""['HP:000111','HP: 000112','HP:000113']""

任何帮助都将不胜感激

我不完全清楚你想做什么，为什么你打开文件'w+'表示转储

然而，如果你有一些东西出现块样式和未引号，这可以很容易地补救通过使用一个小函数:

import sys
from pathlib import Path
import ruamel.yaml
SQ = ruamel.yaml.scalarstring.SingleQuotedScalarString
def flow_seq_single_quoted(lst):
res = ruamel.yaml.CommentedSeq([SQ(x) if isinstance(x, str) else x for x in lst])
res.fa.set_flow_style()
return res
in_file = Path('yaml.yaml') 
in_file.write_text("""
hpoIds:
- HP:000111
- HP:000112
- HP:000113
""")
yaml = ruamel.yaml.YAML()
data = yaml.load(in_file)
data['hpoIds'] = flow_seq_single_quoted(data['hpoIds'])
yaml.dump(data, sys.stdout)

给了:

hpoIds: ['HP:000111', 'HP:000112', 'HP:000113']

至少从2006年9月开始，YAML文件的推荐扩展名是.yaml。
