一下三个模块完美的实现了模块之间的参数传递。
1、将编写好的代码设置成模块
2、设置成模块之后还存在一些导入模块之后，怎么时候执行，怎么执行的问题
这个问题使用如下代码解决。
if __name__==‘__main__‘#如果程序是主函数自己执行的，（意思就是该函数不是被别人import（被调用）执行的），那么久执行shop()函数,你就可以先导入到你的当前代码中，导入的方法为（import _shopping）,此时导入进来的模块将不会执行shop()，你需要调用执行的时候，你只需输入( _shopping.shop() )代码，即可调用执行。_shopping.shop()
else:
shop()
if __name__==‘__main__‘: bank.bank(gouwuche,shopping_userlogin,shangpinname)else: bank(None,None,None)
3、模块之间的参数如何传递系列的问题会呈现出来；
def bank(gouwuche,shopping_userlogin,shangpinname):
5、如何将传递的参数写入日志，并且查询：
使用pickle或者是json,
