Reportlab is a Python library that allows you to make multi-page documents, working with a canvas. I found a nice introduction and tutorial here: https://www.blog.pythonlibrary.org/2010/03/08/a-simple-step-by-step-reportlab-tutorial/
From this tutorial, I created a basic page:
#import the canvas object from pdfgen
from reportlab.pdfgen import canvas
#supply a filename to the canvas object
c = canvas.Canvas("hello.pdf")
# drawstring draws text - starts at the bottom left, so this is 100 points (pixels) from the left margin, and 750 from the bottom
c.drawString(100,750,"Welcome to Reportlab!")
#save the PDF
c.save()
By adding a zero to the bottomup keyword argument you can change where drawstring starts draing text to - this will probably set it to begin at top left The default canvas is A4, this can be changed to other formats (such as US letter) with the following code:
#import the letter format from the pagesizes library
from reportlab.lib.pagesizes import letter
#import the canvas object from pdfgen
from reportlab.pdfgen import canvas
#supply a filename to the canvas object, specify the pagesize to be letter
canvas = canvas.Canvas('myfile.pdf', pagesize=letter)
#grab the width and height for letter - this can be useful to calculate when to add a page break or to define margins
width, height = letter
A form:
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
canvas = canvas.Canvas('myfile.pdf', pagesize=letter)
width, height = letter
and a letter with flowing text:
