Python interpreter

Before you start, check that when you call Python interpreter, the output is:

$ python
Python 3.7.3 (default, May 13 2019, 15:44:23)
[GCC 4.9.2] on linux
Type "help", "copyright", "credits" or "license" for more information.

Output shows that Python 3.7 is set. Invitation >>>, this is a standard invitation from Python interpreter. Interpreter call is executed by python command and to exit you need to type quit(), or press Ctrl+D.

Note

Book will use ipython instead of standard Python interpreter
