python dict和函数不工作

Question

以下是我的文本文件的前20行，我有50K行。

    template<typename Key, typename Info>
    void Sequence<Key,Info>::operator=(const Sequence &x)
    {
        element *ptr=head;
        while(ptr)//deallocating memory
        {
            head=ptr->next;
            delete[] ptr;
            ptr=head;
        }
        x.element *ptr2;// <- it doesn't work - how can I make a ptr for structure of class x here?
// rest of code 
.
.
.
//



    }

我这样读，

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

我写了一本字典以匹配专业，这是字典。

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

我写了一个这样的函数来获取密钥的值，

它没有按预期工作，这可能是什么问题？

以下是我如何获得，它应该返回非匹配键的其他键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'])) ，但事实并非如此。

谢谢。

Answer 1

使用def key_in_dict(p): return (options.get(x, default='Other') for x in p) 方法指定未找到密钥时的默认值。

Rx.Observable.from([1, 2, 3, 4, 5])
  .zip(Rx.Observable.timer(0, 2000), x => x)
  .subscribe(x => console.log(x));

Answer 2

正如Barmar所说，您可以使用get字典方法。我认为以下内容可以为您提供所需内容：

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