Using ConfigObj to Read, Write, and Manage INI Files in Python

ConfigObj is a powerful third‑party Python library that simplifies reading and writing INI configuration files, which are essential in API automation and other backend tasks.

Reading a configuration file

from configobj import ConfigObj
# 读取配置文件
config = ConfigObj('config.ini')
# 获取配置项的值
base_url = config['API']['base_url']
api_key = config['API']['api_key']
print("Base URL:", base_url)
print("API Key:", api_key)

Writing a new configuration file

from configobj import ConfigObj
# 创建配置文件对象
config = ConfigObj()
# 添加配置项和值
config['API'] = {'base_url': 'https://api.example.com',
                 'api_key': 'your-api-key'}
# 写入配置文件
config.write(open('config.ini', 'w'))
print("配置文件写入成功！")

Updating an existing configuration value

from configobj import ConfigObj
# 读取配置文件
config = ConfigObj('config.ini')
# 更新配置项的值
config['API']['api_key'] = 'new-api-key'
# 写入更新后的配置文件
config.write()
print("配置项的值已更新！")

Handling multiple configuration files

from configobj import ConfigObj
# 创建配置文件对象
config = ConfigObj()
# 读取多个配置文件
config.merge(ConfigObj('config.ini'))
config.merge(ConfigObj('config_override.ini'))
# 获取配置项的值（优先使用 override 文件中的配置）
base_url = config['API']['base_url']
api_key = config['API']['api_key']
print("Base URL:", base_url)
print("API Key:", api_key)

Dynamic generation of sections and options

from configobj import ConfigObj
# 创建配置文件对象
config = ConfigObj()
# 动态生成节和选项
sections = ['API', 'Database']
options = {'API': ['base_url', 'api_key'],
           'Database': ['host', 'username', 'password']}
for section in sections:
    config[section] = {}
    for option in options[section]:
        value = input(f"请输入 {option} 的值：")
        config[section][option] = value
# 写入配置文件
config.write()
print("配置文件已生成！")

These examples show how to flexibly read, create, update, merge, and dynamically generate INI configuration files using ConfigObj, helping developers streamline interface automation workflows.
