Exercise 4 - Guessing Games

Exercise 4 - Guessing Games

➤ Try playing this simple game.

import numpy as np
import sys
import os
sys.path.append(os.getcwd()+'/.hidden/')
import guessingGames as gg
gg.guessingGame(nmax=10)

I am thinking of a number between 1 and 10
Make a guess:1
Sorry, try again.
Make a guess:4
Sorry, try again.

➤ Can you write your own version?

A couple of hints to help you:

  • To read input from the keyboard, you can use

x = input(message)

where message is the prompt shown to the user (e.g. ‘Make a guess:’ in gg.guessingGame). Whatever the user types in gets stored in the variable x. Note that x contains a string of characters, even if the user types in a number. You can use int(x) to convert the input to an integer (and float(x) if you want to convert it to a floating-point number).

  • To generate a random integer, you can call the function np.random.randint(lo,hi) where lo is the smallest integer you want to generate, and hi is one greater than the largest integer.

What happens if the user types something in that isn’t an integer? Can you make your version robust?

➤ Here’s another one to play:

gg.higherOrLower(nmax=100)

➤ Try writing your own version.

You should be able to use the code you wrote for guessingGame as a starting point.
