Report Lab is not producing/saving a pdf file

Report lab is not producing a pdf in a very simple example/try:

from arcpy import *
from reportlab.lib.styles import getSampleStyleSheet, ParagraphStyle
from pyPdf import PdfFileWriter, PdfFileReader
from reportlab.pdfgen import canvas
from reportlab.lib.pagesizes import letter, cm
from reportlab.platypus import Paragraph
from reportlab.lib import colors
from reportlab.pdfgen import canvas

filename = "HelloWorld.pdf"
c = canvas.Canvas(filename)
c.drawString(100,750,"Welcome to Reportlab!")
c.save()

These two lines work fine: c.drawString(100,750,"Welcome to Reportlab!") c.save() But is this one that throw the errors. I've tried to change the path, the filename, try the 'r' before the string of text for the path+filename, nothing works.

I've got this error trace:

You need to call showPage():

from reportlab.pdfgen import canvas

filename = "HelloWorld.pdf"
c = canvas.Canvas(filename)
c.drawString(100,750,"Welcome to Reportlab!")
c.showPage()
c.save()
