Python is probably the easiest-to-learn and nicest-to-use programming lan-
guage in widespread use. Python code is clear to read and write, and it is con-
cise without being cryptic. Python is a very expressive language, which means

that we can usually write far fewer lines of Python code than would be required
for an equivalent application written in, say, C++ or Java.
Python is a cross-platform language: In general, the same Python program can
be run on Windows and Unix-like systems such as Linux, BSD, and Mac OS X,
simply by copying the file or files that make up the program to the target
machine, with no “building” or compiling necessary. It is possible to create
Python programs that use platform-specific functionality, but this is rarely
necessary since almost all of Python’s standard library and most third-party
libraries are fully and transparently cross-platform.
One of Python’s great strengths is that it comes with a very complete standard
library—this allows us to do such things as download a file from the Internet,
unpack a compressed archive file, or create a web server, all with just one or a

few lines of code. And in addition to the standard library, thousands of third-
party libraries are available, some providing more powerful and sophisticat-
ed facilities than the standard library—for example, the Twisted networking

library and the NumPy numeric library—while others provide functionality
that is too specialized to be included in the standard library—for example, the
SimPy simulation package. Most of the third-party libraries are available from
the Python Package Index, pypi.python.org/pypi.
