Basic Python programming help?

With no description of what the file looks like and what you're trying to count in it? Not likely.

Someone would have to make a very lucky guess--and that sort of luck should be buying a lottery ticket rather than typing on Y!A.

You have 123abc123def123abc

You are told to count how many 123's there are

while not EOF (end of file) read the next char.

Dose the char match 1? If not, go back to the top of the loop and read read next.

Test for match, no, try again, test for match and Yes, we have a match

We are now at the 5 element which we read in and then compare with '2'. We have a match. matches = matches + 1

Move to next char which is the 6th element and compare it to 'C' and we have another match. We now have a full set of "abc"

So now we go back up to the top of our loop again and read in char 5, compare against 1 ...

Continue until EOF and then display match count.
