The >>> prompt indicates you’re in the Python shell which acceptsPython commands. The command from sympy import * imports allthe SymPy functions into the current namespace. All SymPy functionsare now available to you. To exit the python shell press CTRL+D.I highly recommend you also install ipython, which is an improvedinteractive python shell. If you have ipython and SymPy installed,you can start an ipython shell with SymPy pre-imported using thecommand isympy. For an even better experience, you can try ipythonnotebook, which is a web frontend for the ipython shell.Each section of this tutorial begins with a python import statementfor the functions used in that section. If you use the statement fromsympy import * in the beginning of your code, you don’t need torun these individual import statements, but I’ve included them soyou’ll know which SymPy vocabulary is covered in each section.
