Python Coding

Trinket. Welcome to this Hour of code activity, sponsored by Trinket.io Today we're going to learn the basics of a programming language named Python. Python is fun to learn but is also a Real programming language that powers websites and apps like Yelp.com and Twitter. Run your first program! No need to save the fun stuff until the end. Here's a program in Python. Press Run to see what it does: At the end of this activity we'll come back to this example and you'll see you'll understand quite a lot about how it works. Keep Going! You'll see lots of new things during this tutorial.

Also, for each of the interactive examples you see, there is a Reset button in the left hand menu. Have fun! No content has been added to this page yet. Operators and Operands — How to Think like a Computer Scientist: Interactive Edition. Operators are special tokens that represent computations like addition, multiplication and division. The values the operator works on are called operands. The following are all legal Python expressions whose meaning is more or less clear: 20 + 32hour - 1hour * 60 + minuteminute / 605 ** 2(5 + 9) * (15 - 7) The tokens +, -, and *, and the use of parenthesis for grouping, mean in Python what they mean in mathematics. The asterisk (*) is the token for multiplication, and ** is the token for exponentiation.

Addition, subtraction, multiplication, and exponentiation all do what you expect. (ch02_15) When a variable name appears in the place of an operand, it is replaced with the value that it refers to before the operation is performed. (ch02_16) What if, on the other hand, we had wanted to know how many whole hours there are and how many minutes remain. (ch02_17) Pay particular attention to the first two examples above. (ch02_18) The modulus operator turns out to be surprisingly useful.

Python Tutor - Visualize Python, Java, JavaScript, TypeScript, Ruby, C, and C++ code execution. Python for Beginners | Learn Python Progamming Online. Python Set Up - Google for Education. This page explains how to set up Python on a machine so you can run and edit Python programs, and links to the exercise code to download. You can do this before starting the class, or you can leave it until you've gotten far enough in the class that you want to write some code.

The Google Python Class uses a simple, standard Python installation, although more complex strategies are possible. Python is free and open source, available for all operating systems from python.org. In particular we want a Python install where you can do two things: Run an existing python program, such as hello.py Run the Python interpreter interactively, so you can type code right at it Both of the above are done quite a lot in the lecture videos, and it's definitely something you need to be able to do to solve the exercises. Download Google Python Exercises As a first step, download the google-python-exercises.zip file and unzip it someplace where you can work on it.
