To make sense of this, look at it from right to left. a_list is the list you're mapping. The Python interpreter loops through a_list one element at a time, temporarily assigning the value of each element to the variable elem. Python then applies the function elem ＊ 2 and appends that result to the returned list.〔【出典】"Dive Into Python 3" by Mark Pilgrim ◆【和訳】Fukada & Fujimoto ◆【License】CC-BY-SA-3.0 〕

それにうーんと昔、1960 年代初めとかだと、みんなコンピュータを変更して、いろんな新しい命令を足したり、すっごい TSS 機能を足したりして、だから MIT の PDP-1 は、引退する頃には 60 年代はじめに Digital が届けたときの 2 倍くらいの命令を持ってたし、特別なハードウェア・スケジューラ補助機能や変なメモリマッピング機能なんかもあって、個別ハード装置を特定のTSS ジョブに割り当てたり、その他ぼくでもほとんど知らないようないろんなことになってた。
And the really old days, the beginning of the 1960's people used to modify computers adding all sorts of new instructions and new fancy timesharing features, so that the PDP-1 at MIT by the time it was retired in the mid-seventies had something like twice as many instructions as it had when it was delivered by Digital in the early sixties, and it had special hardware scheduler assisting features and strange memory-mapping features making it possible to assign individual hardware devices to particular timesharing jobs and lots of things that I hardly really know about.〔【出典】日英対訳文・対応付けデータ（独立行政法人情報通信研究機構）〕"_RMS2", "2250055"

Now think about the rise of global networks like email and the web. Lots of "plain text" flying around the globe, being authored on one computer, transmitted through a second computer, and received and displayed by a third computer. Computers can only see numbers, but the numbers could mean different things. Oh no! What to do? Well, systems had to be designed to carry encoding information along with every piece of "plain text." Remember, it's the decryption key that maps computer-readable numbers to human-readable characters. A missing decryption key means garbled text, gibberish, or worse.〔【出典】"Dive Into Python 3" by Mark Pilgrim ◆【和訳】Fukada & Fujimoto ◆【License】CC-BY-SA-3.0 〕
If you have an international keyboard layout, you should set the optionXkbModel to pc102 or pc105, as this will allow mapping of the additional keys specific to your keyboard.〔【出典】Gentoo Linux ◆【License】CC-BY-SA-2.5 ◆【編集】独立行政法人情報通信研究機構 〕
