In Python, the list and element group are a Data Structure: A sequence. Each element in the sequence is assigned a sequence number. The position of the element, the position of the first original element is 0, and so on. Sequence is the most basic data structure. The
shard is equivalent to directly deleting all elements in the shard.
This statement is similar to del number [2: 7].

Welcome to personal website: www.comingnext.cn1. About Python built-in sequence typesA. Differentiate the container sequence by the ability to store different types of data:list, tuple, and collections.deque these sequences can hold different types of dataFlat sequence:STR, Bytes, ByteArray, Memoryview, and array.array, such sequences can only hold one type.B. Classify variable sequences according to whether they can be modified:List, ByteArray, Array.array, Collections.deque, and Memoryview.Imm
In Python, lists and tuples are data structures: sequences, each element in the sequence is assigned an ordinal, the position of the element, the position of the first element is 0, and so on. Sequence is the most basic data structure, lists and tuples have a certain difference between them, that is, the list can be modified, and tuples cannot be modified! If you want to add an element, it is best to use a list

As mentioned in "a large list (1)", the elements in the list can be numbered from left to right from 0 to create an index (if the index is from right to left, numbers starting from-1). An index can be used to extract a
