If..else

Python uses if else statement as follows

If day == “Saturday” or day == ”Sunday”:

print “At least I can sleep in today”

else

print “Oh, No programming today – thats sad”

Challenge

Grade 6 Challenge:

Extend the program above to ask the user about other PC time, such as smart phone, ipad, xbox, ps3 time and add this to the amount of time they spend on the computer

Grade 8 Challenge:

Extend the program again to IF….ELIF…..ELSE. The program should say suitable messages for less than 2 hours per day, between 2 and 3 hours and more than 3 hours.

If..elif…else

The code:

# Program to ask the user for their name and exam mark %.

# It should then print their grade based on

# >90% A*, >80% A, >70% B, >60% C, 60% or less F.

# ask the user for their name

name = input("Enter you name ")

# Ask for the use for their exam mark and convert it to an integer

mark = int(input("what mark did you get? "))

Challenge

Add to this code to make it print out the exam grade based on the mark % the user enters. You will need to use if elif else statements.

Grade 6 Challenge:

Extend your answer above to print a message if the student is above their target grade. You’ll need to ask the user for their target grade.

Grade 8 Challenge:

Extend challenge 1 above to print a message based on how the student is doing compared to their target grade.

If..elif…else, upper(), variables.

# Program to ask the user for their name.

# It should then pose the user 3 questions and ask for answer

# and tell the user if they are right or wrong.

# ask the user for their name

name = input("Enter you name ")

# Pose the question 1

a1 = input ("Q1. which football team plays at Upton Park? ")

if a1 == "West Ham United":

print ("Correct")

The code poses a question and lets the user provide and answer. If they get it right they are told so.

Challenge

Complete the program to ask a total of 3 questions and tell the user the correct answer if they provide the wrong one. You can also change the first question if you wish.

Grade 6 Challenge:

Extend the solution to the program to ignore capital letters in the answers. Thus in the above example all the following “West Ham United”, “WEST ham United”, “west ham united” will all be marked as correct. You might want to use .lower() or .upper()

Grade 8 Challenge:

Extend challenge 1 above to count how many answers the user gets right and displays a summary of the correct number of marks at the end of the quiz.

Import Statement

The statement

import time

allows you to use time features in python. One of these is time.sleep(5) which will lets your program sleep (or wait) for 5 seconds.

Challenge

Writeaprogramthatasks theuser‘Whatisyourquestion?’Theprogramshould respondwith‘Letmethink aboutthat’ and pausesfor10 secondsbeforeresponding with ‘Idon’t wanttoanswerthatquestionrightnow’

Theprogramshould thenask theuserthe questionthattheuserentered, wait for an input,and thenlaugh outloud(lol) attheirresponse.

Challenge13

Write a program that asks the user 5 numbers, you will need to store them and then prints the smallest and largest number in the list.

Hint: You will need a function that has 2 parameters and returns the smaller of the 2. You will also need a second function that returns the larger of 2 numbers.

Grade 6 Challenge:

Extend the program above to take the absolute value of the numbers before finding the smallest and largest.

Grade 6 Challenge:

For loops are good at doing something a set number of times, like times table. Write a program to print out the 6 times table.

Grade 8 Challenge:

For loops can be placed inside one another, such as

for x in range ( 1, 5 ):

for y in range ( 10, 15 ):

print (x, y, "hello – this will get printed lots of times")

Write down what you think will happen, and why.

Challenge15

Ghost.

There is a ghost hidden behind 1 of 3 doors. Write a program to choose a door at random and ask the user to guess which door the ghost is behind. The idea is for the user to avoid the ghost. If the user has avoided the ghost then add 1 to their score, and they have another go as the ghost may have moved doors. If the user has found the ghost then their go is over – print out how many times they missed the ghost.
