Hi,

Sorry you've been having problems. What you need to do is pass an empty tuple 
for the dimension parameter for the creating the variable:

    numLines = goesr_remap.createVariable('numLines', np.short, ())

Then to set the value you do a full slice of the variable and set it to the 
value:

    numLines[:] = 1401
