ZETA Series

GPRS/UMTS/LTE Terminal with GPIO

Telit Easy Script in Python

Telit Easy Script in Python is a high-level Python programming language script
interpreter. Python is often characterized as minimalist, although this applies mainly
to the language’s core syntax and semantics. The standard library provided within the
development environment offers a large number of additional extensions to perform
many complex tasks to enable fast application development.

The ZETA modems offer the Python script interpreter engine with around 3MB of
nonvolatile memory for the user application scripts and data storage. There is an
additional 1.2MB of RAM reserved for Python engine usage and integrated TCP/IP
stack. There are many benefits of the Python programming language and it is already
being used in a wide variety of applications.

Some of the key distinguishing features of Python include:

»

Extremely clear, readable syntax

»

Strong introspection capabilities

»

Intuitive object orientation

»

Natural expression of procedural code

»

Full modularity, supporting hierarchical packages

»

Exception-based error handling

»

High level dynamic data types

»

Extensive standard libraries and third party modules
