Python PEP8: Blank lines convention
我想知道程序部分之间换行符的Python约定是什么? 例如,考虑一下:
1 2 3 4 5 | import os def func1(): def func2(): |
以下两者之间理想的换行分隔应该是什么:
功能?
我已经阅读了PEP8,但是我想确认以上两点。
如果可以查看PEP8的"空白行"部分,则可以找到以下内容:
Surround top-level function and class definitions with two blank lines.
Method definitions inside a class are surrounded by a single blank line.
Extra blank lines may be used (sparingly) to separate groups of related functions. Blank lines may be omitted between a bunch of related one-liners (e.g. a set of dummy implementations).
Use blank lines in functions, sparingly, to indicate logical sections.
关于进口,PEP8声明:
Imports should usually be on separate lines
...
Imports should be grouped in the following order:
standard library imports related third party imports local application/library specific imports You should put a blank line between each group of imports.
因此,对于您的示例,符合PEP8的格式为:
1 2 3 4 5 6 7 | import os def func1(): def func2(): |
为了给出更全面的说明:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 | import re import glob import sys import requests import scrapy from flask import Flask from my_local_module import MyClass def top_level_function1(): pass def top_level_function2(): pass class TestClass(object): def class_method1(): pass def class_method2(): pass class TestClass2(object): def class2_method1(): pass def class2_method2(): pass |
