Hello

I am a masters student, and beginner in python programming. I seek help and
guidance from the tutors here. Thanks in advance.

Problem: Convert DOT files to PDF.

I came across pydot for this and tried following:
#####code####
import os
import pydot
(graph,) = pydot.graph_from_dot_file('hello.dot')
graph.write_png('hellow.png')

Error:
assert process.returncode == 0, process.returncode

AssertionError: 1



Python version: 3.7.4
Development environment: Spyder

Best regards
