In Python, `set` is an unordered and mutable collection data type that does not allow duplicate elements. It can be used to store a unique set of elements.<\/p>\n

A `set` object can be created using curly braces `{}` or the `set()` function. For example:<\/p>\n

# \u4f7f\u7528\u82b1\u62ec\u53f7\u521b\u5efa\u4e00\u4e2aset
<\/p>
my_set = {1, 2, 3, 4, 5}<\/p>
print(my_set)  # \u8f93\u51fa: {1, 2, 3, 4, 5}<\/p>
# \u4f7f\u7528set()\u51fd\u6570\u521b\u5efa\u4e00\u4e2aset<\/p>
another_set = set([5, 6, 7, 8, 9])<\/p>
print(another_set)  # \u8f93\u51fa: {5, 6, 7, 8, 9}<\/p><\/pre>\n
The main features of set include:<\/p>\n
The elements in the set are unordered, so they cannot be accessed by index.<\/p>\n
The elements in the set are unique, any duplicate elements will be automatically removed.<\/p>\n
3. A set is mutable and allows for adding, removing, and modifying elements.<\/p>\n
The elements in a set must be hashable (immutable), therefore they cannot contain mutable types of elements such as lists, dictionaries, etc.<\/p>\n
5. You can manipulate sets using a variety of built-in methods such as adding elements with `add()`, removing elements with `remove()`, finding the union with `union()`, and finding the intersection with `intersection()`.<\/p>\n
Here are some common operations examples for the `set`.<\/p>\n
my_set.add(6)  # \u6dfb\u52a0\u5143\u7d20
<\/p>
my_set.remove(3)  # \u79fb\u9664\u5143\u7d20<\/p>
print(len(my_set))  # \u8f93\u51fa: 5\uff0c\u96c6\u5408\u4e2d\u7684\u5143\u7d20\u4e2a\u6570<\/p>
print(2 in my_set)  # \u8f93\u51fa: True\uff0c\u5224\u65ad\u5143\u7d20\u662f\u5426\u5728\u96c6\u5408\u4e2d<\/p>
union_set = my_set.union(another_set)  # \u6c42\u5e76\u96c6<\/p>
intersection_set = my_set.intersection(another_set)  # \u6c42\u4ea4\u96c6<\/p>
print(union_set)  # \u8f93\u51fa: {1, 2, 4, 5, 6, 7, 8, 9}<\/p>
print(intersection_set)  # \u8f93\u51fa: {5}<\/p><\/pre>\n
In conclusion, `set` is a very useful data type, particularly suitable for handling unordered, unique collections of elements.<\/p>\n","protected":false},"excerpt":{"rendered":"
