the following:

	Those are essentially useless...

		uStr and pStr are required arguments to the instance creation, and

here you bind them to the instance specific uName/pWord attributes. The
class-wide uName/pWord will never be visible unless somewhere you
explicitly use
		Unamepword.uName
or 
		Unamepword.pWord 
in some method of the class, in order to bypass the instance attribute.

	Since you don't show the entire class I can't comment further -- if all
it does is set those attributes you could just as easily use a dictionary

login = Unamepword("bob", "secret")

print login.uName, login.pWord

vs

login = {	"uName" : "bob",		"pWord" : "secret" }

print login["uName"], login["pWord"]

	Note: I'm not necessarily recommending the latter -- just offering
alternatives... If you assume username is always first a simple tuple might
do

login = ("bob", "secret")
print login[0], login[1]

...

UNAME = 0
PWORD = 1

print login[UNAME], login[PWORD]
