如何使用 python 從網站查找信息

Question

我想知道是否可以在 python 中編寫代碼，這將允許我從在線資源中查找信息並將其添加為我的代碼作為字典。 （我想使用它，所以我有一本字典，其中包含哈利波特維基上列出的所有咒語作為鍵，它們的描述作為關聯值（ https://harrypotter.fandom.com/wiki/List_of_spells ））

我正在開始 python 學生，真的不知道如何開始，我想我可以將信息復制為文本文件並從那里進行操作，但我真的希望它也能改變，如果在線源發生變化等。

您可以在此處獲取 wiki 數據並對其進行解析：

https://harrypotter.fandom.com/wiki/List_of_spells?action=edit

看起來拼寫遵循相同的格式，使其易於解析。 它們由新行分隔，因此您可以通過 \n 拆分數據，並解析出每一行。 似乎有兩種不同類型的咒語，以“|”開頭的咒語和其他以'：'開頭的，所以你必須對類型進行不同的解析。 這對你開始有幫助嗎？

===([[Albus Dumbledore's forceful spell|Albus Dumbledore's Forceful Spell]])===

:'''Seen/Mentioned:''' This incantation was used only once throughout the series, and that was by Dumbledore in the [[British Ministry of Magic|Ministry of Magic]], immediately following the [[Battle of the Department of Mysteries]] on [[17 June]], [[1996]], while he duelled Voldemort.

===''[[Unlocking Charm|Alohomora]]'' (Unlocking Charm)===
[[File:Unlocking charm1.gif|235px|thumb]]
:'''Type:''' Charm
:'''Pronunciation:''' ah-LOH-ho-MOR-ah
:'''Description:''' Unlocks doors and other objects. It can also unlock doors that have been sealed with a [[Locking Spell]], although it is possible to bewitch doors to become unaffected by this spell.
:'''Seen/Mentioned:''' Used by [[Hermione Granger]] in [[1991]] to allow [[Trio|her and her friends]] to access the [[Third-floor corridor]]] at [[Hogwarts School of Witchcraft and Wizardry|her school]], which was at the time forbidden; she used it again two years later to free [[Sirius Black|Sirius]]'s cell in [[Filius Flitwick's office|her teacher's prison room]].
:'''Etymology:''' The incantation is derived from the West African Sidiki dialect used in geomancy; it means "friendly to thieves", as stated by [[J. K. Rowling|the author]] in testimony during a court case.<ref name=alomohoracourt>{{cite web |url=http://cyberlaw.stanford.edu/files/blogs/Trial%20Transcript%20Day%201.txt |title=Warner Bros Entertainment, Inc. and J.K. Rowling  v. RDR Books (Transcript) |author=United States District Court, Southern District of New York |date=April 14, 2008 |publisher=Stanford Law School |access-date=October 1, 2015 |quote=Alohomora is a Sidiki word from West Africa, and it is a term used in geomancy.  It is a figure -- the figure alohomora means in Sidiki "favorable to thieves."  Which is obviously a very appropriate meaning for a spell that enables you to unlock a locked door by magic.}}</ref>
:'''Notes:''' Whilst in the first book, when the spell is cast the lock or door must be tapped once, in the fifth, [[Miriam Strout|a healer]] simply points her wand at the door to cast it, and on {{PM}} the wand motion is seen as a backward 'S'.
