The module reportlab seems very good to make pdf files. This is the first post about this library. Let’s start with making a simple new pdf with some text like our hello world script.
I have used this module to create a nice application that adds a page with text to an existing pdf file (made to add an evaluation to tests) in this post here.
This code was taken from the Pythonvsmouse blog. You can find more documentation here with some useful code snippets.
from reportlab.pdfgen import canvas
import os
c = canvas.Canvas("hello.pdf")
c.drawString(100, 700, "First time using reportlab")
c.save()
os.startfile("hello.pdf")
You start from the bottom. To print the text at the start you need to pyt something like 700 as the height.
This is what you should come up to
In the following video there is this code above, just to show how easy it is. The audio is not so good, sorry.
Letter size
The default size of the page is a4. If you want letter size, add this to the code when you use the Canvas class, the pagesize argument=letter, like you see down here:
from reportlab.lib.pagesizes import letter
from reportlab.pdfgen import canvas
canvas = canvas.Canvas('myfile.pdf', pagesize=letter)
width, height = letter
How to set fonts
To set the size and tyope of the fonts, use a code like this
canvas.setFont('Helvetica', 12)
Draw lines
You can draw lines with this code.
- first you set the width of the line
- then you give the coordinates
canvas.setLineWidth(.3) canvas.line(378,723,580,723)

In the next post we will go further into this module to see what we can do with a pdf and python.
