If that's the exact text of your program, then a blank page is exactly 
what you should get.  You define a function to print "Hello World", but 
you never call that function.  All you do is create an empty canvas and 
save it.

So, you either need to do this:

  from reportlab.pdfgen import canvas
  def hello(c):
  ~    c.drawString(100,100, "Hello World")
  c = canvas.Canvas("c:\hello.pdf")
  hello(c)    # <<<<< add this
  c.showPage()
  c.save()


or just write the string in-line:

 from reportlab.pdfgen import canvas
 c = canvas.Canvas("c:\hello.pdf")
 c.drawString(100,100, "Hello World")
 c.showPage()
 c.save()
