Ruth Ware. Lets be a little conventional and print out a "hello". Just type in the following code after you start the interpreter. Nevertheless, it is considered one of the standard textbooks for learning Python. Now lets dive into the wonderful world of Python variables and take our understanding of strings even further. Python is a true object-oriented language, and is available on a wide variety of platforms. Programming, web development, machine learning, and data science are just a few of the industries that use it. It is used in many organizations as it supports multiple programming paradigms. While using W3Schools, you agree to have read and accepted our. endobj Lets take a look at a couple of particular notes here: There are a couple of rules and best practices to help you name your variables: Now that you have a good, preliminary understanding of Python variables, lets take a little bit of time to dive into using Python to do math! We can create strings using single quotes (this 'this'), double quotes (like "this"), or triple quotes (like """this"""), though the last version is used generally for multi-line strings.
