Python comes with a library of standard modules.
Some modules are built into the interpreter; these provide access to operations that are
not part of the core of the language but are nevertheless built in, either for efficiency
or to provide access to operating system primitives, such as system calls.
One particular module deserves some attention: sys, which is built into every Python
interpreter. The variables sys.ps1 and sys.ps2 define the strings used as primary and
secondary prompts if the interpreter is in the interactive mode:
>>> import sys
>>> sys.ps1
'>>> '
>>> sys.ps2
'... '
The variable sys.path is a list of strings that determines the interpreter’s search path
for modules: see what it prints for you when you run the code of the task.
Remember that you can use the &shortcut:CodeCompletion; shortcut after a dot (.) to explore available methods of a module. You can read more about standard modules here.
