Using Python.Com  Challenges

In order to refine your Python skills for the controlled assessment all students should ensure that they understand can complete the following challenges.  If you can’t complete a challenge find out where you are going wrong and correct – do not move on until you have completed each challenge.

Your teacher will provide you with solutions:

If you are unsure about any of the basics work through the introductory sections from the main menu.

Welcome Back 03/09/15

This term we are really going to work at understanding Python:


A Python Crash Course can be found in the following folder:

Hopefully it's shared.

We are also going to complete the Summer Controlled  Assessment.  A link to this can be found here:

A Wee Python Challenge

A Wee Python Challenge

In today's lesson we are going to start with a mini Python challenge.

Your Task:

Answer the two problems below.

Screen dump the code and the output to a Google document and post the URL to the blog.

NOTE:  If you get help from another website or a peer acknowledge this under a heading called 'Sources'.

Problems

1. Write a program in Python which adds up 3 numbers which are inputted by the user.

2. Write a program in Python which finds the maximum number in the list below:

[7,15,4,5,22,32,45,19]

When you have finished the challenge you may continue with the Controlled assessment work:

Extension Challenge (Optional but worth doing for CA)

Write a Python Program for a 'Tic Tac Toe' game.  This is quite a big program and you may want to reserach and try it out as an additional task over the Summer.

A link to a new Python Course will be posted here shortly:

15. Pseudocode and built-in subprograms: random function

Activity 14.1

Pseudocode

Pseudocode, or ‘mock’ code, is another way of describing a program. You will need a copy of the pseudocode used in this course (Appendix B of the specification) to answer thesequestions.

•

What does this pseudocode do?

RECEIVE myName FROM (STRING) KEYBOARD

RECEIVE myAge FROM (INTEGER) KEYBOARD

SET AgeInTen TOmyAge + 10

SEND myName “will be” AgeInTen “in 10 years’ time” TO DISPLAY

•

Write the Python code for this program.

Activity 14.2

•

What does this pseudocode do?

SET score TO 119

IF score < 50 THEN SEND “You have lost” TO DISPLAY

ELSE SEND “You have won” TO DISPLAY

END IF

•

Write the Python code for this program.

Activity 14.3

random() function

•

Copy and run this program code:

•

Run the program a few times. What does it do?

•

What is meant by ‘import random’?

•

What happens if you alter the values to 1, 100?

Activity 14.4

Write a program that acts like a dice. After each ‘throw’ of the dice it should ask if the playerwishes to continue and stop when they enter ‘Y’.

Activity 14.5

Write a program that gives the user 10 chances to guess a number between 1 and 10. It then compares their answer with a randomly generated number and stops the program when the number generated matches the number guessed or when the user is out of guesses.

14. Repetition construct: while loop, flowcharts

Activity 13.1

While command

•

What does this while command do?

•

What is the condition that is being tested and how does it change?

Activity 13.2

Write a program that asks the user if they are hungry. While they reply ‘N’ the program repeats the question, showing how many times they have replied ‘N’.  

When they reply ‘Y’, the program tells them to get something to eat.

Activity 13.3

•

What does this program do?

•

What is the ‘sentry’ variable?

•

What is the condition?

Activity 13.4

Flowcharts and while command

Flowcharts can be used to represent programs. Complete the flow chart for this program.
