The most basic data structure in Python is the sequence. Each element of a sequence is assigned a number – its position or index. The first index binary option demo zero, the second index is one, and so forth.
Python has six built-in types of sequences, but the most common ones are lists and tuples, which we would see in this tutorial. There are certain things you can do with all sequence types. These operations include indexing, slicing, adding, multiplying, and checking for membership. In addition, Python has built-in functions for finding the length of a sequence and for finding its largest and smallest elements. Important thing about a list is that items in a list need not be of the same type. Creating a list is as simple as putting different comma-separated values between square brackets. Similar to string indices, list indices start at 0, and lists can be sliced, concatenated and so on.
