获取 settings.ini 最方便的方法是什么，内容以字典和几个变量的形式出现？

  • 772

需要将字典和变量写入settings.ini文件，（**如果文件不存在，则创建）

字典准备：

dict1 = [
    {'object': 'label', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'button', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'color', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'line', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'unknown', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
]

变量：

theme = light
icon_size = 32
indent = 36

问题：

最方便的方法是什么？配置解析器、yaml 还是 json？（重要的是该文件被称为“settings.ini”）

python

    可以这样写：

    import configparser

dict1 = [
    {'object': 'label', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'button', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'color', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'line', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'unknown', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
]

config = configparser.ConfigParser()

config['DEFAULT'] = {'theme': 'theme', 'icon_size': 32, 'indent ': 36}

for d in dict1:
    config[d['object']] = d

with open('example.ini', 'w') as f:
    config.write(f)

    从ini读取：

    import configparser

config = configparser.ConfigParser()
config.read('example.ini')

print(dict(config['DEFAULT']))
# {'theme': 'theme', 'icon_size': '32', 'indent': '36'}

for section in config.sections():
    print(dict(config[section]))

# {'object': 'label', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command', 'theme': 'theme', 'icon_size': '32', 'indent': '36'}
# {'object': 'button', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command', 'theme': 'theme', 'icon_size': '32', 'indent': '36'}
# {'object': 'color', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command', 'theme': 'theme', 'icon_size': '32', 'indent': '36'}
# {'object': 'line', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command', 'theme': 'theme', 'icon_size': '32', 'indent': '36'}
# {'object': 'unknown', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command', 'theme': 'theme', 'icon_size': '32', 'indent': '36'}

    文件example.ini：

    [DEFAULT]
theme = theme
icon_size = 32
indent  = 36

[label]
object = label
icon = icon
icon_hover = icon_hover
command = command

[button]
object = button
icon = icon
icon_hover = icon_hover
command = command

[color]
object = color
icon = icon
icon_hover = icon_hover
command = command

[line]
object = line
icon = icon
icon_hover = icon_hover
command = command

[unknown]
object = unknown
icon = icon
icon_hover = icon_hover
command = command

  2. 写入文件：

    #!/usr/bin/env python
# -*- coding: utf-8 -*-

import configparser

dictionary = [
    {'object': 'label', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'button', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'color', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'line', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
    {'object': 'unknown', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'},
]

config = configparser.ConfigParser()

config['default'] = {'theme': 'theme', 'icon_size': 32, 'indent ': 36}

for d in dictionary:
    config[d['object']] = d

with open('example.ini', 'w') as f:
    config.write(f)

    从文件中读取：

    with open('example.ini', 'r') as f:
    config.read(f)

dictionary = []
for s in config.sections():
    section = {}
    for k in config[s]:
        v = config[s][k]
        section.update({k: v})
    if s == 'default':
        settings = section
    else:
        dictionary.append(section)

print(dictionary)
print(settings)

    结果：

    [{'object': 'label', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'}, {'object': 'button', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'}, {'object': 'color', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'}, {'object': 'line', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'}, {'object': 'unknown', 'icon': 'icon', 'icon_hover': 'icon_hover', 'command': 'command'}]
{'theme': 'theme', 'icon_size': '32', 'indent ': '36'}
