告诉我们发生了什么：

我在完成这一步时遇到了困难。我尝试了将 medical_records 变量转换为字符串并调用 validate 函数，但测试一直提示“你应该将你的 medical_records 列表转换成字串”。希望获得关于这一步的具体写法或排错指导。
I am having trouble with this step. I tried converting the medical_records variable to a string and calling the validate function, but the test keeps prompting “You should convert your medical_records list into a string.” I would appreciate some guidance on the exact syntax or troubleshooting for this step.

medical_str = str(medical_records)
validate(medical_str)

你目前的代码

# User Editable Region
medical_records = [
    {

        'medications': ['Lisinopril'],

you have not changed medical_records, you have created a new variable, medical_records is still a list of objects, not a string
