A lot of people find reading from a sequential file difficult. Well lets break it down, first of all what is a sequential file? A sequential file is a text based (ASCII or UNICODE) file that is made up of both printing and non printing characters. The end of the file is signalled with EoF, often programmers put data in separate lines using a new line character. Sometimes the files are in CSV format, which means that each line holds a records worth of data.
The basic premise of any Python read file access is
This post will mostly be focused on different ways of doing step 2.
These are the notes I took on the board today, you should now start to put them into your powerpoint at home. Make sure that also include an example question and answer from the past papers.
The Prelim exam for National 5 and Higher Computing Science classes will take place on Wednesday the 20th of January 2016. Both exams will start at 11:30am in the Hall.
Please make sure and bring
You should all be in study mode as the prelim is just after the holidays.
You can use this 2016 H Prelim Revision powerpoint to take notes and help you out.
Use BBC Bitesize or Scholar to study this list of topics.
A trace table is used by a programmer to help simulate the running of a program. The programmer dry runs the program, as they trace each line of code with their finger they record the values in a table that includes the line number of the program.
This is similar to TRACS but it requires the programmer to remember a lot more.

Then it suddenly hit me, this is a form of run length encoding, that we will be covering later in the course. It’s just that in this case the encoding is only for black squares. Anyway I just wanted to share it now while it was topical.
