I'm not sure what the plus sign in the second line signifies 
but otherwise it looks like you will need to process each file 
line by line and concatenate each string.

for line1 in fileA:
     line2 = fileB.readline()
     fileC.write("%s\t%s" % line1,line2)


You might need to strip the lines before writing them...
