for name, age in zip_longest(names, ages, fillvalue="Unknown"): print(f"{name} is {age} years old.") 3. 避免显式循环,多用内置函数 Python 提供了许多高效的内置函数,可以避免for循环,提高代码性能。 3.1 使用map()代替for进行映射 # ❌ 低效写法 numbers = [1, 2, 3, 4] squares = []...
有些编辑器不会保留尾空格,并且很多项目(像CPython)在pre-commit的挂钩调用中会过滤掉尾空格。 总是在二元运算符两边加一个空格:赋值(=),增量赋值(+=,-=),比较(==,<,>,!=,<>,<=,>=,in,not,in,is,is not),布尔(and, or, not)。 如果使用具有不同优先级的运算符,请考虑在具有最低优先级的运算...
#6 – Do not use a single blank line between relatedPython one-liners. For example, if you write the specification of three functions for later implementation, you can simply omit the blank lines aroundone-liner function definitionsto avoid too much whitespace in the code. Like so: deff1()...

PEP是 Python Enhancement Proposal 的缩写,翻译过来就是 Python增强建议书 。 PEP8译者:本文基于 2013-08-02 最后修改的 PEP8 版本翻译,若要查看英文原文,请参考PEP8 回到顶部 二、A Foolish Consistency is the Hobgoblin of Little Minds尽信书则不如无书 ...
5.PEP8规范编写代码 1. 可迭代对象 我们已经知道可以对list,tuple,dict,set,str等类型数据使用for…in…的循环语法从其中依次拿到数据进行使用,我们把这样的过程称为遍历,也叫迭代。 把可以通过for…in…这类语句迭代读取一条数据供我们使用的对象称之为可迭代对象(iterable)。
1、找到python的script目录 2、把ppx.py拷贝到当前目录 3、按住“shift”键,并在空白处右击,选择“在此处选择powershell窗口” 4、在powershell中输入:autopep8 --in-place --aggressive --aggressive ppx.py 并执行该命令 5、对比原始代码,可以发现如下标红处都已优化 ...
