I have taken a basic course in pascal long ago, will I be able to understand this?
The Pascal will probably help, depending on how long ago you learned it. If it's faded away, you'll be starting more or less from scratch. If you still remember some of it, many of the concepts will be paralleled in Python.
How do I find a tutor or someone to help me through the difficult parts?
You can ask questions here, there are people who will help :)
