Python特效代码简单(python做动画特效)
python圣诞树代码简单
```python# Python 圣诞树代码for i in range(1, 6): for j in range(1, i+1): print('*', end=' ') print('\n')```
拓展:如果想改变树的形状,可以在代码中添加更多的控制参数,如在每一行中添加不同的空格数,使得树的形状不一样。同时可以通过添加HTML标签,使用CSS样式来改变圣诞树的颜色、背景和文字等等。

python简单的编程代码
输入两个数字,比较大小,然后按照大小输出
def cmpNum():
a = input("请输入一个数字:")
b = input("请输入一个数字:")
if a = b:
print(a, b)
else:
print(b, a)
cmpNum()
结果一:
请输入一个数字:159
请输入一个数字:456
456 159
结果二:
请输入一个数字:9568
请输入一个数字:1452
9568 1452
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~
