例如,我们还可以将这个文件路径追加到一个列表中,然后对列表进行迭代以处理每个文件: # Iterate over the files in the current "root"forfile_entryinfiles:# create the relative path to the filefile_path = os.path.join(root, file_entry)print(file_path) 我们也可以使用root + os.sep() + file_en...
This means we only scan the main list once. We do scan the unique items list for each entry in the main list, but even in a worst case this greatly reduces the number of comparisons. Fastest implementation: Use a Set lookup Those two examples let us check for duplicates. The improved ...
