<type 'tuple'> Sets 集合 集合对象是一组无序排列元素组成。集合有两种不同的类型:可变集合(set)、不可变集合(frozenset)。 可变集合:可以添加和删除元素,它不是可哈希的,因此不能用做字典的键也不能做其他集合中的元素。 不可变集合:与可变集合相反,不可修改,有哈希值,可用做字典的键或作为集合中的一个成员。
12.Lists and Tuples in Python: Conclusion01:48 Start Now cherianzachariahonAug. 5, 2020 There is a lot of new little things that I learnt from this course. Thank you and keep up the good work. I am loving it so far. ← Browse All Courses...
This article discussed the two famous data structures used in Python, especially in Machine Learning and Data Science fields, Lists and Tuples. We learned about the various operations performed on these data types and accessing elements from them. We will discuss two other data structures, sets, ...

While the + operator only works with two lists, this unpacking technique can be used for other iterables (e.g. tuples or sets), too. c=[*a,*b]# [1, 2, 3, 4] a=[1,2]b=(3,4)# c = a + b# TypeError: can only concatenate list (not "tuple") to listc=[*a,*b]# [...
Don’t do items += "Test" or items.extend("Test") or Python will add 4 individual characters to the list, resulting in ['Roger', 1, 'Syd', True, 'T', 'e', 's', 't']Remove an item using the remove() method:items.remove("Test")...

there are places in Python itself where a tuple is used when a list makes more sense. When you define a function with *args, args is passed to you as a tuple, even though the position of the values isn’t significant, at least as far as Python knows. You might say it’s a tuple...
