os.path.getsize(path): 返回文件的大小(字节)。 示例: import os # 获取当前工作目录 current_directory = os.getcwd() print("当前工作目录:", current_directory) # 使用相对路径 relative_path = "subfolder/file.txt" absolute_path = os.path.join(current_directory, relative_path) print("绝对路径:...

由于os是built-in module,即使在同目录下有同名模块,解释器依然可以找到正确的os模块,而redis属于第三方模块,默认安装位置是 python 环境变量中的site-packages下,解释器启动之后会将此目录加入sys.path,按照上面所说的查找顺序,优先在执行文件所在的目录查找,由于其在sys.path的首位,因而本地的redis被导入。 2.交互...

Sometimes, however, absolute imports can get quite verbose, depending on the complexity of the directory structure. Imagine having a statement like this: Python from package1.subpackage2.subpackage3.subpackage4.module5 import function6 That’s ridiculous, right? Luckily, relative imports are a...
is_absolute() False 要从相对路径获得绝对路径,可以将Path.cwd() /放在相对Path对象的前面。毕竟,当我们说“相对路径”时,我们几乎总是指相对于当前工作目录的路径。在交互式 Shell 中输入以下内容: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 >>> Path('my/relative/path') WindowsPath('my/...
getatime(),getctime(),getmtime()和getsize() 依次指:返回上次访问该path的时间;返回该path的系统ctime,在unix系统上对应于该path上次元数据更改的时间,在windows上对应文件的创建时间;返回该path上一次修改的时间;返回该path的文件大小 In[16]:path='./.zshrc'In[17]:getatime(path),getctime(path),getmtime...
fromlist (Optional): 被导入的 submodule 名称 level (Optional): 导入路径选项,Python 2 中默认为 -1,表示同时支持 absolute import 和 relative import。Python 3 中默认为 0,表示仅支持 absolute import。如果大于 0,则表示相对导入的父目录的级数,即 1 类似于 '.',2 类似于 '..'。 使用示例如下: ...
