代碼結構
PyQt安裝完后Python\Lib\site-packages\PyQt5 有相關的pyd文件，這個是編譯后的python庫文件，相當於DLL或者是SO庫文件，代碼編輯器無法直接預覽， 所以Pycharm幫我們根據pyd反編譯得到：
C:\Users\xxxx\.PyCharm2018.3\system\python_stubs\498501734\PyQt5\Qt.py 這個文件是方便查看接口的參數和返回值及文檔說明
PyQt 包涵的代碼模塊

上面的py文件很清楚列除了所以PyQt 的類， 以及類所在的模塊，這樣清晰的羅列類似的結構關系。
在調試代碼得時候，為了方便可以直接全部導入，但是這樣會導致占用很多內存，而且運行啟動速度，但是很方便，我們在發布代碼時候改成按需導入即可
from PyQt5.Qt import *
按類名檢索
在PyQ官網還提供了按類名首寫字母檢索，之前說過PyQt和源生Qt的命名方式完全一樣，Qt所以的類都是以打頭。官網PyQt類大全
可以點擊下面類的首先字母查看對應的所有類， 然后Ctrl+F查找定位
3 | A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y
隨便點擊一個類能進入類的詳情頁面，里面包涵了該類所屬的模塊、該類的父類、繼承該類的子類、類的描述、枚舉常量、接口等信息
模塊描述
如上面描述Qt庫把各個類集合到特定的功能模塊里，下面大致了解一下各個模塊的說明
QtGui 涵蓋了各種各樣的圖形相關功能的類，比如字體、圖形、背景、圖標、顏色等等操作類；
QtCore 涵蓋了圖形無關的Qt核心模塊，比如信號/曹、時間、文件、目錄、數據、連接、網絡等非GUI圖形的操作類；
QtWebKite 涵蓋了網頁響應的類，使用他可以實現與瀏覽器類似的功能，實現web展現；
QtSql 是有關於數據庫相關的操作
Qt 模塊在內部導入所有Qt相關類
Qt 很多類用的時候可能記不清，那比如我想使用QPushButton類應該怎么導入，在哪個模塊里？有兩種方法可以導入:
- 方法一
from Qt import *
button = QPushButton()
- 方法二 使用
Pycharm開發工具， 把光標放在QPushButton上按 的Alt+Enter自動導入
