Lesson goal: Data science: find the maximum value in a file

Previous: Find the average of some numbers | Home | Next: Find the minimum value

Again suppose that sample.dat contains a list of amounts spent by patrons during lunch at a retaurant. Let's see if we can tell the owner what his maximum sale amount was. In other words, let's find the maximum number in the file sample.dat.

We'll need a loop to be able to examine each number in the file, and we'll apply some coding logic to try and figure what the maximum value is in the data file.

Now you try. Try to complete the code and find the maximum number in the file sample.dat.
