希望此功能可以对您有所帮助（我正在使用Python 2.7）：
import osdef get_files_by_file_size(dirname, reverse=False): """ Return list of file paths in directory sorted by file size """ # Get list of files filepaths = [] for basename in os.listdir(dirname): filename = os.path.join(dirname, basename) if os.path.isfile(filename): filepaths.append(filename) # Re-populate list with filename, size tuples for i in xrange(len(filepaths)): filepaths[i] = (filepaths[i], os.path.getsize(filepaths[i])) # Sort list by file size # If reverse=True sort from largest to smallest # If reverse=False sort from smallest to largest filepaths.sort(key=lambda filename: filename[1], reverse=reverse) # Re-populate list with just filenames for i in xrange(len(filepaths)): filepaths[i] = filepaths[i][0] return filepaths
