How can I make pdf with snippet in reportlab

I am new in programming and have got weak background to deal with snippet. My problem is that I have no idea about how to use the snippet included in the ReportLab user guide

https://www.reportlab.com/docs/reportlab-userguide.pdf

I just follow by this protocol All I have done is the code in section 2.1 - 2.6 But in section 2.7, I have no idea how to use function (def...) to create pdf

My question is:

(1) What is the basic background that I should know? (2) Could you please give me some example code that show how to deal with this stuff?

Solution

Try this tutorial. The snippet below should create a file "hello.pdf" in the same directory as your python script.

from reportlab.pdfgen import canvas

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