那么求相对路径的问题可以看作两个过程: 先从 a 回溯到交汇点, 再从交汇点流向 b. 回溯的计算, 可以获得 ‘…/’ 的数量. 顺流的计算, 可以获得从交汇点到 b 的路径. 这两个相加就是 b 相对于 a 的相对值了. 函数也非常简单, 表示如下: defcalculate_relative_path(a,b):""" 计算相对路径: 已知两...
os.path()模块还可以获取绝对路径,检查它是否存在,并获取父目录。我们还可以使用os.path.dirname()函数或访问os.path.split()函数的第一个元素来获取父目录。split()方法更常用于从路径中获取文件名: # Gather other propertiesprint("Is a symlink: ", os.path.islink(file_path))print("Absolute Path: ",...
/usr/bin/env python3''' My First Script: Calculate an important value. '''print(355/113) 它是如何工作的... 与其他语言不同,Python 中几乎没有样板。只有一行开销,甚至#!/usr/bin/env python3行通常是可选的。 为什么要将编码设置为 UTF-8?整个语言都是设计为仅使用最初的 128 个 ASCII 字符。
When the import system encounters an explicit relative import in a module without __package__ set (or with it set to None ), it will calculate and store the correct value ( __name__.rpartition(‘.’)[0] for normal modules and __name__ for package initialisation modules). 这句话的意...
