python字典和功能不工作

这是我的文本文件的前20行，我有这样的50K行。python字典和功能不工作

prov_type|prov_type_desc 
0|FAMILY PRACTICE/CLINIC 
1|FAMILY PRACTICE 
2|ALLERGIST 
3|DERMATOLOGIST 
4|INTERNIST 
5|NEUROLOGIST 
6|NEUROSURGEON 
7|OB/GYN 
8|OPTHAMOLOGIST 
9|ORTHOPEDIST 
10|OTOLARYNGOLOGIST 
11|PATHOLOGIST 
12|PEDIATRICIAN 
13|PLASTIC SURGEON 
14|COLON AND RECTAL SURGERY 
15|PSYCHIATRIST 
16|RADIOLOGIST 
17|SURGEON 
18|THORACIC SURGEON 
19|UROLOGIST 
20|ANESTHESIOLOGIST

我读这样的，

ovations = pd.read_csv("Ovations.txt",sep='|',dtype=object) 
ovations.rename(columns={'prov_type_desc':'specialty'},inplace=True)

我写了一本字典，以匹配特产，这里是字典。

我为了得到该键的值写了这样的功能，

def key_in_dic(p): 
    return next((options[x] for x in p if x in options), 'Other') 
ovations['specialty_adj'] = key_in_dic(list(ovations['specialty']))

它无法按预期工作，有什么能在这个问题？

下面是我如何，我应该返回其他非匹配键，它是ALLERGIST，但事实并非如此。

谢谢。

也许补充，它是如何工作的，并突出它应该如何不匹配？ – Dilettant

已更新，请检查 – subro

为什么不使用'options.get（x，default ='Other'）'为不存在的专业指定默认值？ – Barmar

正如Barmar已经指出的那样，您可以使用get字典的方法。我认为以下应该给你想要的东西：

ovations["specialty_adj"] = ovations["specialty"].apply(lambda x: options.get(x, "Other"))

谢谢，它按预期工作。 – subro

还有一个帮助，我想返回'专业'，如果它不匹配，你能建议我该怎么做？ – subro

乐意帮忙。请注意，您需要在这里为字符串比较匹配拼写，因为'options'包含'FAMILYPRACTICE/CLINIC'，但在数据框中它被写入'FAMILY PRACTICE/CLINIC'并且有空格。根据你想达到的目标，你可以尝试在lambda表达式中使用'options.get（x.replace（“，”“），”Other“'，但你应该接受这个答案作为正确的答案， – ValD

使用dict.get()方法指定找不到密钥时的默认值。

def key_in_dict(p): 
    return (options.get(x, default='Other') for x in p)
