11/27/2023 0 Comments Simple data types in pythonYou can also slice strings, which means that you select parts of strings: # Range Slicing Here are some other basic operations that you can perform with strings For example, you can use * to repeat a string a certain number of times: # Repeat You can also apply the + operations on two or more strings to concatenate them, just like in the example below: x = 'Cake' In Python, you can create strings by enclosing a sequence of characters within a pair of single or double quotes. Strings are collections of alphabets, words, or other characters. Dynamically typed languages are the languages where the type of data an object can store is mutable. That is because it is a dynamically typed language. Note that in Python, you do not have to explicitly state the type of the variable or your data. Take a look at the following DataCamp Light Chunk and try out some of the integer and float operations!ĮyJsYW5ndWFnZSI6InB5dGhvbiIsInNhbXBsZSI6IiMgRmxvYXRzXG54ID0gNC4wXG55ID0gMi4wXG5cbiMgQWRkaXRpb25cbnByaW50KHggKyB5KVxuXG4jIFN1YnRyYWN0aW9uXG5wcmludCh4IC0geSlcblxuIyBNdWx0aXBsaWNhdGlvblxucHJpbnQoeCAqIHkpXG5cbiMgUmV0dXJucyB0aGUgcXVvdGllbnRcbnByaW50KHggLyB5KVxuXG4jIFJldHVybnMgdGhlIHJlbWFpbmRlclxucHJpbnQoeCAlIHkpIFxuXG4jIEFic29sdXRlIHZhbHVlXG5wcmludChhYnMoeCkpXG5cbiMgeCB0byB0aGUgcG93ZXIgeVxucHJpbnQoeCAqKiB5KSJ9 You can use it for rational numbers, usually ending with a decimal figure, such as 1.11 or 3.14. "Float" stands for 'floating point number'. You can use an integer to represent numeric data and, more specifically, whole numbers from negative infinity to infinity, like 4, 5, or -1. In the next sections, you'll learn more about them! Integers Python has four primitive variable types: They are the building blocks for data manipulation and contain pure, simple values of data. These are the most primitive or basic data structures. The former are the simplest forms of representing data, whereas the latter are more advanced: they contain primitive data structures within more complex data structures for special purposes. Generally, data structures can be divided into two categories in computer science: primitive and non-primitive data structures. This implementation requires a physical view of data using some collection of programming constructs and basic data types. Now, data structures are actually an implementation of Abstract Data Types or ADT. Abstract Data Type and Data StructuresĪs you read in the introduction, data structures help you to focus on the bigger picture rather than getting lost in the details. With it, you'll discover methods, functions, and the NumPy package. The course gives an introduction to the basic concepts of Python. In DataCamp's free Intro to Python for Data Science course, you can learn more about using Python specifically in the data science context.
