Data Structures in Pythonis suitable for a first course in data structures and algorithms, especially common in the first two years of a computing major. Introduces the basics of algorithms and data structures, including sorting, runtime complexity, lists, stacks, queues, hash tables, trees, and...
Output ['Java','Python', 'C', 'c++', 42 Accessing Element To access the element from the list we need to use the index number. The index must be an integer. Let's see a few examples: print(Programming_languages[0]) Python Copy The above snippet will return first element in the li...

Data structures are basically just that - they are structures which can hold some data together. In other words, they are used to store a collection of related data.There are four built-in data structures in Python - list, tuple, dictionary and set. We will see how to use each of them...
