import configparser

config = configparser.ConfigParser()
config.read('config.ini')
# 获取所有节点
sec = config.sections()
print(sec)
# 获取单个节点下所有选项
db = config.options(section="database")
print(db)
# 获取单个节点下某个选项值
username = config.get(section="database", option="username")
print(username)
# 获取某个节点下所有选项及选项值
value = config.items(section="database")
print(f"获取到的值是：{value}")

# 增加一个节点
config.add_section("db")
# 给节点增加选项和值
config.set(section="db", option="usr", value="chuanzhang")
# 保存操作
with open(os.path.dirname(__file__)+'/config.ini', mode='w+') as file:
  config.write(file)
  file.close()

# 删除节点下某个选项
config.remove_option(section="db", option="pwd")
with open(os.path.dirname(__file__)+'/config.ini', mode='w+') as opt:
    config.write(opt)
    opt.close()
# 删除节点
config.remove_section("db")
# 删除后保存
with open(os.path.dirname(__file__)+'/config.ini', mode='w+') as data:
    config.write(data)
