shutil.copy2(source_file, destination_file) # 或者,如果你已经确认source_file和destination_file是Path对象: shutil.copy2(source_file, destination_file) 方法二:使用 shutil.copyfile() (不复制元数据如权限) import shutil source_file = "/path/to/source/file.txt" destination_file = "/path/to/dest...
引用当前工作目录下的文件:file = open("file.txt", "r") 引用当前工作目录下的子目录中的文件:file = open("subdirectory/file.txt", "r") 使用相对路径的好处是,它更具可移植性。无论在哪个计算机上运行代码,只要相对路径保持不变,代码就可以正常工作。 4、综合项目 项目简介:我们将设计一个中药材管理系...
with open('data.txt', 'r') as f: data = f.read()open() 接受文件名和模式作为参数。 r 是以只读模式打开文件。如果要将数据写入文件,请将w作为参数传入: with open('data.txt', 'w') as f:data = 'some data to be written to the file' f.write(data)在上面的示例中,open() 打开用于读...

To build Windows installer, seeTools/msi/README.txt. If you wish, you can create a subdirectory and invoke configure from there. For example: mkdir debug cd debug ../configure --with-pydebug make make test (This will fail if youalsobuilt at the top-level directory. You should do amake...
然后,在不输入它的情况下,通过键入mkdir mydirectory/mysubdirectory 如果您现在输入ls,您应该看到mydirectory被列为可用目录。你现在可以打字了cd mydirectory/mysubdirectory 您将位于新创建的子目录中。让我们测试一下echo函数。在终端中,键入echo "Hello, world!"终端应该响应Hello, world!
