One last thing to note: if you just need to loop over the unique items right away there's no need to convert back to a list. This works fine: >>>forcolorindict.fromkeys(all_colors):...print(color)...bluepurplegreenredpink That works because all forms of iteration are the same in ...
mylist = ["a", "b", "a", "c", "c"] mylist = list(dict.fromkeys(mylist)) print(mylist) Create a dictionary, using the List items as keys. This will automatically remove any duplicates because dictionaries cannot have duplicate keys.Create a Dictionary mylist = ["a", "b", "a...

通过将列表转换为set,我们可以自动去除重复元素,然后再将其转换回列表。 list(set(original_list))将original_list转换为set,然后再转换回列表。 方法2: 使用列表推导式 列表推导式是一种简洁的创建列表的方法。我们遍历original_list,并将不在unique_list中的元素添加到unique_list中。 [unique_list.append(x) fo...

初学者经常会遇到如何移除list中重复元素的问题。 这个问题在其他语言中可能需要for循环什么的,而在python中不用这样,非常简单,只需要将list作为set的构造函数构造一个set,然后再将set转换会list就可以了。 如下代码: 代码语言:javascript 代码运行次数:0
To remove duplicates from a Python list while preserving order, create a dictionary from the list and then extract its keys as a new list: list(dict.fromkeys(my_list)).
