Gudio Van Rossum Main()

I've written a few main() functions in my time. They usually have a structure roughly like this:

"""Module docstring.

This serves as a long usage message.
"""
import sys
import getopt


def main():
    # parse command line options
    try:
        opts, args = getopt.getopt(sys.argv[1:], "h", ["help"])
    except getopt.error, msg:
        print msg
        print "for help use --help"
        sys.exit(2)
    # process options
    for o, a in opts:
        if o in ("-h", "--help"):
            print __doc__
            sys.exit(0)
    # process arguments
    for arg in args:
        process(arg) # process() is defined elsewhere

if __name__ == "__main__":
    main()

SQL

SQL Injection

 A SQL Injection is a type of virus that you type into a user input field that allows access to the database that the field is connected to. If done right a SQL Injection can leave devastation on a computer and site. SQL Injection's can be done in a variety of ways and forms, and they are becoming increasingly dangerous via the web.

Different SQL codes can be used to override SQL database code and gain information.

SELECT user from users where password = 'pass123' OR email = 'email@m.com'
