我在做什么？ 我有使用PyQt构建的GUI界面，它通过验证指纹来授予用户访问权限。
我正在使用指纹传感器R305，用于我的模块。
我的问题？ 我在GIT上提供了我的代码，它将数据保存在特定的ID中。 但它无法搜索指定的指纹。

在完成代码之后，我在您的GUI代码中使用new（）来生成用于保存指纹模板数据的随机ID值。但是在你的搜索代码中，你正在检查数组[0,1]中r [2]的值，它实际上是你当前存储的id列表。这就是为什么您的搜索程序无法找到您的指纹 要在python中生成id的动态值，可以使用动态数组或循环。 将其替换为GUI代码中的new（）：
lst=[]
def new(self):
print("new")
def main1(self):
for z in range(0,256):
if z in lst:
z=z+1
self.new()
else:
lst.append(z)
a=z
z=z+1
break
return a
通过调用main1（）来获取id的值：
id=self.main1()
在搜索代码中进行以下更改：
if r[0]==0 and r[2] in lst:
