Initializing help system before first use

# xpress.attr

Purpose

Internal object class used for the attributes of an xpress.problem. The user can read attributes from a problem, but cannot create objects of this class. Also, an attribute of a problem may be read, but it cannot be set.

Example
The following example creates a problem and then prints one of its attributes:

    import xpress as xp

    p = xp.problem(x)

    x = [p.addVariable() for _ in range(10)]

    print(p.attributes.cols, "variables")  # will print "10 variables"
