このデータ構造に関連する最後の問題です

In the last question involving this data structure,

学期をキーとしてまた値を特定の人物が携わる各コースのリストとして含むディクショナリを作成する必要があります

we want to create a dictionary that contains the hexamesters as the keys and the values as a list of each course a given person is involved with.

まずはDaveを見てみましょう

So let's look at Dave.

2012年4月の2つのコースに携わっています

For April 2012 he's involved in 2 courses:

コンピューターサイエンス入門と暗号技術の応用です

cs101, his intro course, and cs387, the Applied Cryptography course.

ディクショナリは継続しますが構造は同じ状態にとどまります

And the dictionary continues on, but the structure stays the same,

それはキーが学期で値が携わる人のコースのリストです

where the key is the hexamester and the value is a list of courses for which that person is involved.

おそらく携わるとはどう意味かとお思いでしょう

So 1 question you may be asking yourself, what does it mean to be involved?

データ構造に戻って行うことは

And if we go back to our data structure, what we're going to do

コースに関連している名前と値の組を見ることです

is look at the name value pairs associated with the course.

Steveを探すとWeb開発、Webエンジニアリング

So if we're looking for Steve, Steve is associated with his class, cs253,

ブログの作成に関連しています

the Web Engineering - Building a Blog.

このように見ていきます

And so that's what we're going to do.

各コースを1つずつ調べ名前と値の組で値を見ていきます

We're going to go through each course, looking at the value in the name value pairs,

値が探しているものだったら

and if the value is what we're looking for,

そのコースを学期のキーに関連する

then we're going to add that course to our dictionary

ディクショナリに追加します

associated with the key of that hexamester.

やや複雑で答えは長くなりますが

It sounds a little convoluted, and the answer is a little long,

考え方はいたってシンプルです

but it's really a simple idea.

まず出力ディクショナリを作成します

The first thing I'm doing is creating the output dictionary.

各学期を調べていきます

We're going to go through each hexamester.

各学期の各コースを調べていきます

We're going to go through each course in each hexamester.

名前と値の組の各キーを調べていきます

We're going to go through each key in the name value pairs.

もし値がすべてに関連している場合それが探している人物です

If the value associated with all this is the person we're looking for,

そこで出力ディクショナリをアップデートします

then we're going to update our output dictionary.

この学期をキーとしてすでに出力ディクショナリに追加している場合このコースを学期に関連するリストの末尾にappendします

If we've already added this hexamester as a key to the output dictionary, then we're just going to append this course at the end of the list associated with that hexamester.

もしくはコースがたった1つの値である新しいリストを作成します

Otherwise we're going to create a new list for which the course is the sole value,

これらすべてのループが終了したら出力ディクショナリを返します

and once we're done with all these for loops, we're going to return our output dictionary.
