Revision Questions 2

The Problems

Write programs to do the following. Take screenshots of your code and upload them as a word document.

1. Prompt the user to enter the number of bits in a byte. If they answer 8 print correct, otherwise print “try again.” The program should loop until the user gets the correct answer.
2. Use a for loop to print out the 5 times table.
3. Create a list containing the following names: Ann, Sue, Andy, Steve, Charlotte, Craig, Mark, Raza. Now print out all the names, one after the other
4. Create a dictionary called french containing the following data: chien – dog, chat – cat, vache – cow, cheval – horse, mouton – sheep. Loop through the keys printing out the associated values.

Extension

1. Follow the link to find the text of the poem THE RIME OF THE ANCIENT MARINER: http://www.textfiles.com/etext/FICTION/coleridge-rime-371.txt
2. Copy the text into a file called rime.txt
3. Write a python program that reads rime.txt into a list.
4. Modify your program so that it counts how many lines there are in the list.
5. Modify the program further so that it counts how many words there are in the list.
6. Modify the program so that it counts how many times the word “the” appears.
7. Can you count the frequency of letters in the poem? In other words, how many times does ‘a’ appear, ‘b’ appear, ‘c’ appear and so on…

Time in Words

Given a time in numbers we can convert it into words. For example:

• 5:00 Five o’clock
• 5:10 Ten minutes past five
• 5:15 Quarter past five
• 5:30 Half past five
• 5:45 Quarter to six
• 5:47 Thirteen minutes to six

Write a program which inputs two numbers (the first between 1 and 12, the second between 0 and 59 inclusive) and then prints out the time they represent, in words. You should follow the format of the examples above. Your program should then terminate.

Sample run
Hours: 4
Minutes: 12
Twelve minutes past four

Partial Solution

The following code should start you off. It will answer some times correctly but not all. You will have test the code and then add extra lines to fix it.

times = ["o'clock","One","two","three","four", "five", "six",
	 "seven","eight","nine","ten","eleven","twelve","thirteen","fourteen",
	 "quarter","sixteen","seventeen","eighteen","nineteen","twenty",
	 "twenty one","twenty two","twenty three","twenty four",
	 "twenty five","twenty six","twenty seven","twenty eight",
	 "twenty nine","Half past"]

hours = 4
minutes = 12

if minutes>30:
    print(times[60-minutes]+ " to " + times[hours])
else: 
    print(times[minutes] + " past " + times[hours])

Test the code with examples given at the top of the screen.

The test data at the top of the screen is not exhaustive. Think of some other times that are not covered. Adjust your code accordingly.

Have you considered all the options? There is some test data at the bottom of this page…

Paste your completed code to a word document

Extension

1. Which times, when written in words, have the longest length?
2. Write a program that outputs times in 24 hour clock format, eg 13 hours 0 minutes outputs 13:00 and 9 hours 15 mins prints out 09:15.  You must include the leading 0s!
