學python編程難嗎？

你好，我很高興回答你的問題。

作為Python用戶，讓我們談?wù)剛€人感受。在工作中，我總是嘗試用Python來代替shell，以便結(jié)合實際操作加深我的印象。下面是我的學習過程，了解學習python是否困難。

最后，我們可以根據(jù)自己的興趣選擇合適的開發(fā)框架來實現(xiàn)一些主要的功能需求。如scratch-crawler框架、Django框架、flash框架等，通過各種框架的使用，可以提高開發(fā)效率。隨著我們自己項目的積累，python編程不再困難。

一開始一切都很困難。作為一種非常流行的語言，Python非常容易使用。然而，要走得更遠，我們還需要繼續(xù)深入研究。困難的程度取決于你付了多少錢。

好吧，就這些。我希望我的回答能幫助你。

python__getattr__和__setattr__應(yīng)該怎么理解？

getattruuuuu這是一個內(nèi)置方法。當點號用于獲取實例屬性時，如果該屬性不存在，則在設(shè)置類實例屬性時自動調(diào)用uuuuuGetAttruuuuMethod

uuuSetAttruuuuuMethod，如j.name=5uSetAttruuuMethod self。[name]=5

因為這個類是從dict繼承的，它是dict的超類

所以self[attr]=value相當于調(diào)用dict的下標方法

和a={}a[attr]=value

python類里的私有變量如何定義？

Python沒有私有變量，任何定義的變量都可以直接調(diào)用，但一般來說，在定義的變量之前和之后添加兩個下劃線，并將該變量視為專用變量，如下代碼所示：

class person:defuuuuu inituuuuuuuuu（self）：self.uuuu Privateuuuuu=100p=person（）print（“uuuuuu Privateuuuuuuuuuuuuuu：”，p.uuuu Privateuuuuuuu）print（“p contains variables:”，dir（p））

output:__100p是一個包含變量的：100p是一個包含100個P的100個P的100個P的100個P的100個P的100個P的100個P的100個P的100個P的100個P的100個P的包含變量：[“uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu100級的階級，、“uuuuuDeluuuuuuuuuuuuuuuuuuuuuuuuuuu ”、、““ uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu“，” uuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuprivateuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu。打印結(jié)果取決于其內(nèi)部存儲結(jié)構(gòu)和輸出方式。
