创建的变量：
amount，把传入的交易的金额，变成浮点数并存入变量amount。
interest，本地交易操作的利息。
old_balance，账户余额。
new_balance，交易后的金额数。
执行的操作：
首先判断交易类型，是否为全局配置文件中的定义的交易类型的中的一种，分别有还款，提款，转账，消费。
如果交易类型存在，判断交易操作的方法，
如果操作的方法为plus，则把交易金额添加入账户余额中。
如果操作的方法为minus，则从交易金额中，减去交易金额以及利息。
如果减完后的金额为负数，就返回提示信息：”你当前的额度不足完成本次提款操作，你的余额为***“,退出此函数，并返回一个空值。
如果交易后的金额正常，就更新用户的json数据库中的余额信息。
然后通过accounts.dump_account(account_data)函数把更新后的json信息写入到json文件中。
并返回更新后的用户账户json信息。
如果交易类型不存在，就返回错误提示。
返回值：
如果正常运行，就返回交易后的用户账户json信息。
否则，返回一个空值。
