We will learn about the differences between list, sequence, and slice data types in Python in this article. Lists − In Python, a list is a type of data that can hold multiple values in a single variable. You can think of it like a shopping list that contains multiple items. For example, you could have a list of numbers like [1, 2, 3, 4, 5] or a list of names like ["John", "Jane", "Bob", "Sue"]. Number_List = [1, 2, 3, 4, 5] Name_List = ["John", "Jane", "Bob", "Sue"] Sequences − In Python, a sequence is a type of data ... Read More

Sequence Data Types are used to store data in containers in the Python computer language. The different types of containers used to store the data are List, Tuple, and String. Lists are mutable and can hold data of any type, whereas Strings are immutable and can only store data of the str type. Tuples are immutable data types that can store any sort of value. List The sequential data-type class includes the list data type. The list is the sole mutable data type in the sequential category. It can store any data type's values or components. Many procedures in the ... Read More

We are accustomed to using the * symbol to represent multiplication, but when the operand on the left side of the * is a list, it becomes the repetition operator. The repetition operator makes multiple copies of a list and joins them all together. Lists can be created using the repetition operator, *. For example, Examplenumbers = [0] * 5 print numbersOutputThis will give the output −[0, 0, 0, 0, 0][0] is a list with one element, 0.  The repetition operator makes 5 copies of this list and joins them all together into a single list. Another example using multiple ... Read More

In Python, a list is an ordered sequence that can hold several object types such as integer, character, or float. In other programming languages, a list is equivalent to an array. Concatenation of lists is an operation that adds the elements of one list to the end of another. We're discussing list data structures here, therefore we'll join the elements of one list to the end of another. In this article, we will show you how to concatenate lists in python. The following are the different methods to accomplish this task − Using Concatenation(+) Operator Using For Loop(Naive Method) ... Read More
