Python高难度代码例子、Python最复杂代码例子

#IT教育# #IT# #程序员# #人工智能#

最近学习pytorch,看到下面的Python高难度代码例子和Python最复杂代码例子:

from google.colab import output as colab_output

from base64 import b64decode

from io import BytesIO

from pydub import AudioSegment

RECORD = """

const sleep = time = new Promise(resolve = setTimeout(resolve, time))

const b2text = blob = new Promise(resolve = {

const reader = new FileReader()

reader.onloadend = e = resolve(e.srcElement.result)

reader.readAsDataURL(blob)

})

var record = time = new Promise(async resolve = {

stream = await navigator.mediaDevices.getUserMedia({ audio: true })

recorder = new MediaRecorder(stream)

chunks = []

recorder.ondataavailable = e = chunks.push(e.data)

recorder.start()

await sleep(time)

recorder.onstop = async ()={

blob = new Blob(chunks)

text = await b2text(blob)

resolve(text)

}

recorder.stop()

})

"""

def record(seconds=1):

display(ipd.Javascript(RECORD))

print(f"Recording started for {seconds} seconds.")

s = colab_output.eval_js("record(%d)" % (seconds * 1000))

print("Recording ended.")

b = b64decode(s.split(",")[1])

fileformat = "wav"

filename = f"_audio.{fileformat}"

AudioSegment.from_file(BytesIO(b)).export(filename, format=fileformat)

return torchaudio.load(filename)

waveform, sample_rate = record()

print(f"Predicted: {predict(waveform)}.")

ipd.Audio(waveform.numpy(), rate=sample_rate)

js 的Promise函数对象编程,字符串javascript函数对象,IPython解释js对象,解释结果和python代码结合,IPython Shell显示非字符串数据,python音频使用IPython简单调用。

复杂Python模块下的多知识点结合代码,是Python高难度代码的体现。

Js的Promise理解为动态函数,比C++的类成员函数和全局函数这类静态形式的函数处理灵活,不过初学者理解起来麻烦。代码里sleep和b2text都代表一些处理函数,也就是几行代码,而不是数据。通常来讲,变量一般代表数据,但是这里代表了指令。

python编程,求大神,在线等,急

按照题目要求编写的Python程序如下

class Grade(object):

def __init__(self,grade):

self.grade=grade

class Class(object):

def __init__(self,bclass):

self.bclass=bclass

class Teacher(Grade,Class):

def __init__(self,grade,bclass,subject,name):

Grade.__init__(self,grade)

Class.__init__(self,bclass)

self.subject=subject

self.name=name

def run(self):

print("老师的姓名%s,年级%s,班级%s,学科%s" %(self.name,self.grade,self.bclass,self.subject))

class Student(Grade,Class):

def __init__(self,grade,bclass,age,name):

Grade.__init__(self,grade)

Class.__init__(self,bclass)

self.age=age

self.name=name

def run(self):

print("学生的姓名%s,年龄%d,年级%s,班级%s" %(self.name,self.age,self.grade,self.bclass))

T=Teacher('五','3','数学','张三')

S=Student('四','2',10,'李四')

val=input("请输入打印老师(T),学生(S):")

if val=='T':

T.run()

else:

S.run()

源代码(注意源代码的缩进)

求简洁优美的python代码例子、片段、参考资料

建议你去看一本书:《计算机程序的构造与解释》。里面用的语言是Scheme,一种Lisp的方言。通过这本书学习程序的抽象、封装,以及重要的函数式编程思想。等看完这本书以后,你在来写写Python代码,就知道如何让其简洁直观而又不失其可读性了。

同时,要让代码写得简洁,你也得熟悉Python本身,充分挖掘其能力。Python内建的几个高阶函数:map,reduce,filter,enumerate等等,lambda表达式,zip函数,以及标准库里强大的itertools、functools模块,都是函数式编程的利器。此外Python本身提供了许多非常好的语法糖衣,例如装饰器、生成器、*args和**kwargs参数、列表推导等等,也是简化代码的有效手段。还有,Python有着强大的库。多参考官方的文档了解其原理和细节,我相信你也能写出高效简洁的代码的。

其实代码的简洁没有什么捷径,它要求你了解你要解决的问题,所使用的语言和工具,相关的算法或流程。这些都得靠你自己不断地练习和持续改进代码,不断地专研问题和学习知识。加油吧,少年!

楼下让你参考PEP 20,其实不用去查,标准库里的this模块就是它(试试import this):The Zen of Python(Python之禅)。它就是一段话:

让我们来做个小游戏吧:统计上面这段话的单词总数目,以及各个单词的数量(不区分大小写),然后按字典顺序输出每个单词出现的次数。要求,例如it's和you're等要拆分成it is和you are。你会怎么写代码呢?如何保持简洁呢?

下面是我的参考答案,争取比我写的更简洁吧~

import?re

p?=?re.compile("(\w+)('s|'re|n't)?")

wc?=?{}

tail_map?=?{?"'s"?:?'is',?"'re"?:?'are',?"n't":?'not'}

for?m?in?re.finditer(p,?s):

????word?=?m.group(1).lower()???????????????????#?Get?the?word?in?lower?case

????wc[word]?=?wc.get(word,?0)?+?1??????????????#?Increase?word?count

????tail?=?m.group(2)???????????????????????????#?Get?the?word?tail

????if?tail?is?not?None:????????????????????????#?If?a?word?tail?exists,

????????tail?=?tail_map[tail]???????????????????#?map?it?to?its?full?form

????????wc[tail]?=?wc.get(tail,?0)+1????????????#?Increase?word?count

print?('Total?word?count:?%d'%sum(wc.values()))?#?Output?the?total?count

max_len?=?max(map(len,?wc.keys()))??????????????#?Calculate?the?max?length?of?words?for?pretty?printing

for?w?in?sorted(wc.keys()):?????????????????????#?Sort?the?words

????print?('%*s?=?%d'%(max_len,?w,?wc[w]))?????#?Output

python代码怎么写?

python3.6代码:

cnt=0

whileTrue:

print("请输入分数:")

i=input()

if(noti):

print("输入有误!")

print("学生人数:"+str(cnt))

int i;

min = max = score[0];

avg = 0;

for(i=0; in; i++)

baiavg += score[i];

if(score[i] max)?

规范的代码:

Python采用强制缩进的方式使得代码具有较好可读性。而Python语言写的程序不需要编译成二进制代码。Python的作者设计限制性很强的语法,使得不好的编程习惯(例如if语句的下一行不向右缩进)都不能通过编译。其中很重要的一项就是Python的缩进规则。

一个和其他大多数语言(如C)的区别就是,一个模块的界限,完全是由每行的首字符在这一行的位置来决定(而C语言是用一对花括号{}来明确的定出模块的边界,与字符的位置毫无关系)。
