可以用 Python 编程语言做哪些神奇好玩的事情

  这个就很多了,比如有一个PythonChallenge,你可以使用python闯关.还可以使用scrapy做爬虫,采集自己感兴趣的东西.还有机器学习什么的,还是看你对哪方面感兴趣了.如果解决了您的问题请采纳!如果未解决请继续追问

  

使用Python编程

  symbol?=?{'+',?'-',?'*',?'/',?'%'}

  s?=?input('请输入算式:')

  if?len(symbol?-?set(s))?

  ????try:

  ????????print("{0}?=?{1}".format(s,?eval(s)))

  ????except?ZeroDivisionError:

  ????????print('除数不能为?0?')

  ????except:

  ????????print('error')

  else:

  ????print('error')

  

可以用 Python 编程语言做哪些神奇好玩的事情

  1、制作软件.比方可以制作任何你想开发的软件,比计算器

  2、采集数据.采集是它的强项.你想下载岛国片,批量下载就用它写最好了

  3、制作网站,很多网站都是用python编写的,比方豆瓣和知乎

  4、科学计算,科学计算也是python的特长,它可以做到matlap这样的软件的效果!

  总之,它是一门编程语言,和其他编程语言一样,可以做很多工作

  

如何像Python高手一样编程

  展开全部

  任何语言都是一门艺术,下面分析一下Python之禅:

  1. 在命令行输入:

  import this

  2. 结果如下:

  Beautiful?is?better?than?ugly.

  Explicit?is?better?than?implicit.

  Simple?is?better?than?complex.

  Complex?is?better?than?complicated.

  Flat?is?better?than?nested.

  Sparse?is?better?than?dense.

  Readability?counts.

  Special?cases?aren't?special?enough?to?break?the?rules.

  Although?practicality?beats?purity.

  Errors?should?never?pass?silently.

  Unless?explicitly?silenced.

  In?the?face?of?ambiguity,?refuse?the?temptation?to?guess.

  There?should?be?one--?and?preferably?only?one?--obvious?way?to?do?it.

  Although?that?way?may?not?be?obvious?at?first?unless?you're?Dutch.

  Now?is?better?than?never.

  Although?never?is?often?better?than?*right*?now.

  If?the?implementation?is?hard?to?explain,?it's?a?bad?idea.

  If?the?implementation?is?easy?to?explain,?it?may?be?a?good?idea.

  Namespaces?are?one?honking?great?idea?--?let's?do?more?of?those!3. 中英文对照解释如下:

  Beautiful?is?better?than?ugly.

  #?优美胜于丑陋(Python以编写优美的代码为目标)

  Explicit?is?better?than?implicit.

  #?明了胜于晦涩(优美的代码应当是明了的,命名规范,风格相似)

  Simple?is?better?than?complex.

  #?简洁胜于复杂(优美的代码应当是简洁的,不要有复杂的内部实现)

  Complex?is?better?than?complicated.

  #?复杂胜于凌乱(如果复杂不可避免,那代码间也不能有难懂的关系,要保持接口简洁)

  Flat?is?better?than?nested.

  #?扁平胜于嵌套(优美的代码应当是扁平的,不能有太多的嵌套)

  Sparse?is?better?than?dense.

  #?间隔胜于紧凑(优美的代码有适当的间隔,不要奢望一行代码解决问题)

  Readability?counts.

  #?可读性很重要(优美的代码是可读的)

  Special?cases?aren't?special?enough?to?break?the?rules.

  Although?practicality?beats?purity.

  #?即便假借特例的实用性之名,也不可违背这些规则(这些规则至高无上)

  Errors?should?never?pass?silently.

  Unless?explicitly?silenced.

  #?不要包容所有错误,除非你确定需要这样做(精准地捕获异常,不写except:pass风格的代码)

  In?the?face?of?ambiguity,?refuse?the?temptation?to?guess.

  #?当存在多种可能,不要尝试去猜测

  There?should?be?one--?and?preferably?only?one?--obvious?way?to?do?it.

  #?而是尽量找一种,最好是唯一一种明显的解决方案(如果不确定,就用穷举法)

  Although?that?way?may?not?be?obvious?at?first?unless?you're?Dutch.

  #?虽然这并不容易,因为你不是?Python?之父(这里的Dutch是指Guido)

  Now?is?better?than?never.

  Although?never?is?often?better?than?*right*?now.

  #?做也许好过不做,但不假思索就动手还不如不做(动手之前要细思量)

  If?the?implementation?is?hard?to?explain,?it's?a?bad?idea.

  If?the?implementation?is?easy?to?explain,?it?may?be?a?good?idea.

  #?如果你无法向人描述你的方案,那肯定不是一个好方案;反之亦然(方案测评标准)

  Namespaces?are?one?honking?great?idea?--?let's?do?more?of?those!

  #?命名空间是一种绝妙的理念,我们应当多加利用(倡导与号召)

  

那个编程大人知道下面用python怎么编写出来?

python经典程序实例(python数据分析5个案例)

(a) 3个人在餐厅吃饭,想分摊饭费.总共花费

  print(35.27*(1+0.15)/3)

  print(12.5*16.7)

  print((12.5+16.7)*2)

  def?convert(f):

  ????#?不知道什么是整除问题,所以没办法帮你解决

  ????return?5?/?9?*?(f?-?32)

  temperature?=?54

  print(convert(temperature))

  def?evaluateTime(S,?v):

  ????return?S/v

  distance?=?200

  speed?=?80

  print(evaluateTime(200,?80))
