This tutorial is fully interactive and it is powered by Java. Please select Always trust content from this publisher when you will see a pop-up window. Please wait while the Java downloading the library for this tutorial. If Java is not installed, you still can see the examples, but they will be interactive.
Left window is a code editor which can be used to type Python commands. Press the [Run] button on the right to run these commands and to see the output. You can change vertical divider position with the mouse if the output does not fit to the right window.
Let's get familiar with the interactive prompt. Type:
and press [Run]. You will see “ok”. This means that you can talk to the interactive Python. In fact, now you have learned how to print a string (“ok”). You can type the same a new text in the editor, and press [Run]. For example, let's print ok on different lines using “\n” as a separator:
where two backslashes indicate your comment for this code. Again, press [Run]. You will see a pop-up window with the 3 lines of “ok”. The reason why you got a pop-up window instead inline output, is because the text did not fit to the on-line window. You can type several commands on one line, but separated them with ”;”
In some cases you can edit example and run the modified code. In such cases you will see a green border around such codes. Try to change 'ok' to something else and print “output”
If you are not the registered member, you cannot run the code and cannot see the outputs. But you can still read this manual. For example, non-members will see the following code example: with non-active [Run] button.
You can download the standalone application to work with symbolic math. This application runs on any computer (Windows, Linux, Mac) However, you should be a full member.
