![]() The easiest way to learn which keys do what in Emacs is to follow the built-in tutorial. If you try to paste code into Emacs, for instance, then you may find the standard Ctrl + V keystroke doesn’t work. There are some odd key mappings in Emacs, however. Emacs responds as expected to the arrow keys, as well as the Enter, Backspace, Del, Home, End, and Tab keys.Emacs highlights the opening bracket or parenthesis whenever you type a closing bracket or parenthesis.Emacs changes the indentation to appropriate locations when you hit Tab on an indented line.Emacs indents lines following for and if statements automatically.Emacs highlights variables and constants differently from Python keywords.You may recognize this code as the Sieve of Eratosthenes, which finds all primes below a given maximum. You can download all the files referenced in this tutorial at the link below:ġ MAX_PRIME = 100 2 3 sieve = * MAX_PRIME 4 for i in range ( 2, MAX_PRIME ): 5 if sieve : 6 print ( i ) 7 for j in range ( i * i, MAX_PRIME, i ): 8 sieve = False : Major update adding new code samples, updated package availability and info, basic tutorial, Jupyter walk-through, debugging walk-through, testing walk-through, and updated visuals.You should have some experience developing in Python, and your machine should have a Python distribution already installed and ready to go. Add source control functionality using Gitįor this tutorial, you’ll use GNU Emacs 25 or later, although most of the techniques shown will work on older versions (and XEmacs) as well.Debug Python code using integrated Emacs tools.Run and Test Python code in the Emacs environment.Write Python code to explore Emacs capabilities.Build a basic Python configuration for Emacs.Set up an Emacs initialization file to configure Emacs.Install Emacs on your selected platform.In this tutorial, you’ll learn about using Emacs for Python development, including how to: To this day, GNU Emacs and the XEmacs variant are available on every major platform, and GNU Emacs continues to be a combatant in the Editor Wars. It was adopted into the GNU project by Richard Stallman in the early 1980s, and GNU Emacs has been continuously maintained and developed ever since. One of the most feature-rich editors available is Emacs.Įmacs started in the mid-1970s as a set of macro extensions for a different code editor. Then, you can try to find editors that have those features. To choose the right code editor, you have to start by knowing which features are important to you. Many developers explore numerous editors as they grow and learn. That is why transpose and sort and transpose back does not work.Finding the right code editor for Python development can be tricky.

So I think I can transpose the data, sort and transpose it back. The second one is concatenating the data with itself. If you want to replicate observations, you could have multiple OUTPUT statements in your code. I don't think PROC TRANSPOSE necessarily sorts the columns, I think it'll probably list variables according the order in which in comes across them.Īs for efficiency, I guess that really depends on what the system can handle. Proc sort data = a_contents (keep = name) out = a_sort Proc contents data = sashelp.adomsg out = a_contents noprint * in a new datastep use the ATTRIB statement to with the macro variable above * creating a macro variable with the contents of the above list * PROC CONTENTS - to get a listing of the variables A PROC SORT should do the trick for rows.įor columns, I would like to know if there's a function/proc which will do this too.
