Theos.rename()method raises the FileExistsError or OSError when the destination file name already exists. This can be avoided by wrapping our code in thetry-exceptblock. Use theisfile(‘path’)function before renaming a file. It returns true if the destination file name already exists. We ca...
``` # Python script to rename multiple files in a directory import os def rename_files(directory_path, old_name, new_name): for filename in os.listdir(directory_path): if old_name in filename: new_filename = filename.replace(old_name, new_name) os.rename(os.path.join(directory_path...
Keep in mind if the "dest" already exists then the FileExistsError will be thrown in Windows and in the case of UNIX, an OSError will be thrown. Renaming only the Extension of the file in Python Sometimes you might want to rename the extension of your file and this can be quickly ...
file-like Object:像open()函数返回的这种有个read()方法的对象,在Python中统称为file-like Object。除了file外,还可以是内存的字节流,网络流,自定义流等等。file-like Object不要求从特定类继承,只要写个read()方法就行。 StringIO就是在内存中创建的file-like Object,常用作临时缓冲。 • 写文件 调用open( ...

运行python /path/to/filename时,Python 做两件事: 将目录/path/to添加到模块路径中。 执行/path/to/filename中的代码。 当运行python/path/to/directory/时,Python 的行为就像我们输入python/path/to/directory/__main__.py一样。 换句话说,Python 会做以下两件事: ...
