The command for running it interactive is %run -i hello.py Tab completion
INSTALL IPYTHON 3 CODE
If you want to test the code interactive, you will have to add the -i switch when you use %run. You can list the content of the files in your current folder with the ls command The code in hello.py will run, but the functions in it will not be available for interactive calls. IPython will look for that file in the current folder. To run python code that you have saved to a file (example hello.py), you use the command %run (in our case %run hello.py).
Then go back to IPython and run the file again. If something goes wrong, just go back to the text editor, fix the error, save and exit. If you want to test the code interactive, use the %run -i, otherwise, you can just use %run. You save the file and load it into IPython. The basic workflow in IPython is that you use the text editor to edit your code. You start IPython by typing “ ipython” in your terminal.

If you are on another system, please take a look here Let’s go ahead and see how an installation can look like on a system running Mac. There is an alternative called “IPython” which you can install by typing apt-get install IPython (see the install section below) When its installed you can just start it by typing IPython in the terminal IPython gives you all that you get in the basic interpreter but with a lot extra (line numbers, advanced editing, more functions, help functions etc)Īs I wrote above, if you are on a Ubuntu system, you can install IPython by typing apt-get install IPython in your terminal. The default interactive Python shell can sometimes feel to basic. IPython is an interactive shell for the Python programming language that offers enhanced introspection, additional shell syntax, tab completion and rich history.

In the future I’ll also write about “ The IPython Notebook“, which is a web-based interactive environment where you can combine code execution, text, mathematics, plots and rich media into a single document. I will leave the parallel computing part for another time. While IPython has two main components (an interactive Python Shell and an architecture for interactive parallel computing), this post will be about the Python shell. The goal of this article is to write a short introduction to IPython.
