J.R. Johansson (jrjohansson at gmail.com) The latest version of this IPython notebook lecture is available at http://github.com/jrjohansson/scientific-python-lectures. The other notebooks in this lecture series are indexed at http://jrjohansson.github.io. Python code is usually stored in text files with the file ending ".py": Every line in a Python program file is assumed to be a Python statement, or part thereof.

Python code is usually stored in text files with the file ending ".py": Every line in a Python program file is assumed to be a Python statement, or part thereof. The only exception is comment lines, which start with the character # (optionally preceded by an arbitrary number of white-space characters, i.e., tabs or spaces). Comment lines are usually ignored by the Python interpreter. To run our Python program from the command line we use: On UNIX systems it is common to define the path to the interpreter on the first line of the program (note that this is a comment line as far as the Python interpreter is...

In this notebook we will deal mainly with syntax and semantics in Python we explore some basic expressions in Python we introduce some of the most important control flow statements This is a Jupyter notebook. It is an interface allowing us to combine code (in this case Python) and formatted text in a unified way. The basic unit in a notebook is a cell.

You are right now reading the content of a "Markdown" cell, designed to input formatted text. There are also 'Code' cells, designed to input executable code. intermediate level Python starting from a basic programming background basic knowledge in at least one object oriented programming language must know: variables, types, functions, basic I/O handling good to know: objects, classes, attributes, function arguments

Official Github repository: https://github.com/tuw-python/tuw-python-2022WS This notebook comes from A Whirlwind Tour of Python by Jake VanderPlas (OReilly Media, 2016). This content is licensed CC0. The full notebook listing is available at https://github.com/jakevdp/WhirlwindTourOfPython. Conceived in the late 1980s as a teaching and scripting language, Python has since become an essential tool for many programmers, engineers, researchers, and data scientists across academia and industry. As an astronomer focused on building and promoting the free open tools for data-intensive science, I've found Python to be a near-perfect fit for the types of problems I face day to day, whether...

The appeal of Python is in its simplicity and beauty, as well as the convenience of the large ecosystem of domain-specific tools that have been built on top of it. For example, most of the Python code in scientific computing and data science is built around a group of mature and useful packages: NumPy provides efficient storage and computation for multi-dimensional data arrays. SciPy contains a wide array of numerical tools such as numerical integration and interpolation. Jupyter notebook Homework 1/HW 1.1 - Introduction to the IPython notebook.ipynb In this class, you will be using the IPython Notebook to write code and written responses to assignments.

The notebook consists of a series of cells. For example, this text is in what is called a "Markdown cell". The following cell is a "code cell": You can tell what the type of a cell is by selecting the cell, and looking at the toolbar at the top of the page. For example, try clicking on this cell. You should see the cell type menu displaying "Markdown", like this:

In the notebook, there are two modes: edit mode and command mode. By default the notebook begins in command mode. In order to edit a cell, you need to be in edit mode. This tutorial should take at most 3-4 hours to fully work through. You can read it in HTML or PDF versions, or from the Sage notebook click Help, then click Tutorial to interactively work through the tutorial from within Sage. Though much of Sage is implemented using Python, no Python background is needed to read this tutorial.

You will want to learn Python (a very fun language!) at some point, and there are many excellent free resources for doing so: the Python Beginner’s Guide lists many options. If you just want to quickly try out Sage, this tutorial is the place to start. For example: This tutorial should take at most 3-4 hours to fully work through. You can read it in HTML or PDF versions, or from the Sage notebook click "Help", then click "Tutorial" to interactively work through the tutorial from within Sage.

You will want to learn Python (a very fun language!) at some point, and there are many excellent free resources for doing so including [PyT] and [Dive]. If you just want to quickly try out Sage, this tutorial is the place to start. For example: If you do not have Sage installed on a computer and just want to try some commands, use it online at http://sagecell.sagemath.org. See the Sage Installation Guide in the documentation section of the main Sage webpage [SA] for instructions on installing Sage on your computer. Here we merely make a few comments.

The Sage download file comes with “batteries included”. In other words, although Sage uses Python, IPython, PARI, GAP, Singular, Maxima, NTL, GMP, and so on, you do not need to install them separately as they are included with the Sage distribution. However, to use certain Sage features, e.g., Macaulay or KASH, you must install the relevant optional package or at least have the relevant programs installed on your computer already. Macaulay and KASH are Sage packages (for a list of available optional packages, type "sage -optional", or browse the “Download” page on the Sage website).
