    Python is a comparatively simple programming language, compared to c++. Although some of the benefits of c++ are abstracted away in python, they are replaced with an overall easier to learn language with many “intuitive” features. For this reason it is common and recommended by most professionals that people new to programming start with python.

  • Perl Programming

    Perl is an open-source, general-purpose interpreted programming language. Used often for CGI, Perl is also used for graphics programming, system administration, network programming, finance, bioinformatics, and other applications. The Perl languages borrow features from other programming languages including C, shell scripting (sh), AWK, and sed. They provide powerful text processing facilities without the arbitrary data-length limits of many contemporary UNIX command line tools, facilitating easy manipulation of text files.
