Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.

Open and run the file shown in the folder above.  It should give you a list of the 25 most common words in written English, and various ways of analysing them:

List of words

If you run this program, you should see 7 headings just waiting to be filled in!

 

See how many of the bits of information from A to G you can show, using these hints:

Problem Hint
A - number of words The len function gives the number of items in any sequence.
B - first 5 words Use the syntax sequence[start:stop] .
C - last 3 words You can use negative numbers to say how many items before the end of the sequence you want to stop.
D - every 5th word Use the syntax sequence[start:stop:step value] .
E - four-letter words Use the iterator for X in Y:, and within this loop test whether the len of each item equals 4.
F - Words starting with w Use the same iterator syntax, but this time apply the startswith method to each item to see if it begins with a w.
G - words in order Tuples are immutable, so use the list function to convert your tuple to a list then apply the sort method.
