对教科书中垃圾代码的批判
整洁的代码让人感到有“代码感”，整齐划一，简直没有办法再整洁了，而垃圾的代码让人头痛，单单看着就头痛，更别说作为一个高中生，竟然还要看着教科书和练习中的垃圾代码写题。哎。
人们都说Python代码简洁，“甚至写代码还要拿着一把尺子”，但人们似乎完全忽视了其他语言可以完全比Python整洁，所以我们可以得到一个结论：
代码的整洁只取决于编写者本身，而和语言一点关系都没有。
Python限制缩进，必须让你写出这样的代码：
if something:
doSomething()
但若你是个不擦屁股的流氓，你也可以滥用这种所谓“优势”：
def someJunkFunction():
while some_thing:
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
doSomeTHing()
for some_iterator in some_list:
something()
someOtherThing()
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
for some_thing in some_other_list:
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
doSomeTHing()
for some_iterator in some_list:
something()
someOtherThing()
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
特别是再教科书和练习中，你没有那么大一页纸，但那些没有素养的技术老师们永远把代码写在寥寥几个函数中，但凡有稍微拆分一下代码的结构就谢天谢地了，于是，我们在书中看起来像这样：
def someJunkFunction():
while some_thing:
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
doSomeTHing()
for some_iterator in some_list:
something()
someOtherThing()
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
for some_thing in some_other_list:
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
doSomeTHing()
for some_iterator in some_list:
something()
someOtherThing()
if something:
doThing()
doOtherThing()
if some_other_thing:
doSomething()
doSomeOtherThing()
else:
doSomeChecks()
if some_other_other_thing:
doSomeOtherOtherThing()
else:
doSomeThhhhhhing()
doSomeThhhhhhhing()
doSomeOtherChecks()
if some_check_failed:
doSomeOtherOtherChecks()
doSomeThiiiing()
while some_predicate:
doSomeThiiiiiing()
doOOOOOOOTHERTHING()
这还是老师有些良心，愿意为你眼前的代码添加长名字的情况。随着时间的推移，我们领到的试卷总算是将代码分块了，但永远都会违反SRP，OCP，LSP，ISP，DIP等基本设计原则，对象到处随意操控，而且名字！！！名字！！！名字！！！照样用单字符的名字！！！根本没有改正！！！写长名字你会死啊？你是没钱装IDE吗？？？
最终，今年，我们看到的是诸如此类的代码，没有任何改善（从53 2024 A版上面摘来）：
s="1a20b3"
s=s[::-1]
t,sum=0,0
for ch in s:
if "0" <= ch and ch <= 9:
t=t*10+int(ch)
else:
sum+=t
t=0
print(sum)
还有（二叉查找树，同样摘自53）：
class BTNode:
def __init__(self,data=None,left=None,right=None):
self.data=data
self.left=left
self.right=right
class SBTree: # 这个名字取的太傻逼了，跟技术老师们的水平很相配
def __init__(self,root=None):
self.root=root
def insert(self,root,data):
if self.root is None:
self.root=BTNode(data)
elif data<root.data:
if root.left is None:
_____(1)_____
else:
self.insert(root.left,data)
else:
if root.right is None:
root.right=BTNode(data)
else:
_____(2)_____
def inorder(self,root):
if root is None:
return _____(3)_____
print(root.data,end=",")
def search(self,root,key):
if root is None or root.data==key:
return root
elif key<root.data:
return _____(5)_____
else:
return _____(6)_____
if __name__=="__main__":
a=[3,5,2,6,4,1]
print(a)
sbt=SBTree()
for i in a:
sbt.insert(sbt.root,i)
sbt.inorder(sbt.root)
print()
k=int(input())
p=sbt.search(sbt.root,k)
if p is not None:
print(k,p.data)
else:
print(k,p)
我起草过Dimensium Coding Standard，我是不是整洁代码的实行者一目了然。身为深陷整洁代码中的开发者，对这种代码及其仇恨。渴望教育部能发通知下令整改代码规范和整洁要求，让技术考试和练习更考研素养，而非阅读理解。
