python - Name of arguments in a function not defined

Question

I have defined def TrackXY_by_QI(im, QI, sho, xm, ym): Then some code follows. I return return xnw,ynw. I want to now print the result, so I type z = TrackXY_by_QI(im, QI, sho, xm, ym) print (z)

But then I get z = TrackXY_by_QI(im, QI, sho, xm, ym) 339 print (z)

NameError: name 'QI' is not defined How can I fix this?
