RANDOM NUMBERS

When working with random numbers in python, the first thing that you need to do is type the following line at the top of your program:

To display a random number between 1 and 100 INCLUSIVE, use this code :

import random

num = random.randint(1,100)

print(num)

birds = ["Robin","Pigeon","Starling"]

Create an algorithm that:

Asks the user if they fed any birds.
If the answer is yes, ask them for the name of the bird.
If the name of the bird is inside the array birds, then ask the user how many of that bird did they feed.
Calculate and display the total number of birds that have been fed.
The process repeats as long as the user enters “yes” when asked if they fed any birds.

Arrays

An arrays is a data structure which can store multiple values, however all of the data must be of the same data type.

Arrays are static data structures meaning it can not GROW or SHRINK.

Arrays & Lists

A list is also a data structure that stores multiple values, under 1 identifier.

However the data can be of DIFFERENT data types.

A list can grow and shrink.

The way you create a list in python is exactly the same as an array using [ ]

However if it grows or shrinks while the program is running, it means it’s a list.

Lists

#Creates an empty list/array called numbers.

numbers = [ ]

#Loops 4 times.

for x in range(4):

#Ask the user for a number

num = int(input("Enter a number"))

#Adds the number to the end of the list.

numbers.append(num)

#Displays the list

print(numbers)

Append means adding something to the end.

Text files

Advantages of storing data on a text file:

Data is not lost when the computer is switched off as data is stored permanently.
Data can be used by more than one program or reused when a program is run again.
Data can be backed up or archived.
Data can be transported from one computer to another.

Appending to a text file

When you open a file in write mode, it will either create a new file for you or overwrite an existing file with the same name.

If you want to open an existing file but don’t want to overwrite the contents that is already inside it, you need to open it in APPEND MODE.

This will allow you to add data to the end of the file rather than overwrite existing content.

Why we use subroutine/subprograms?

They perform a frequently used operation within a program that can be called when needed and that can be reused by another program.

Advantages of subroutine

Breaks down a program to make it easier to create and test as each subroutine can be tested separately.
Reuse code and avoids repetition so quicker to develop programs as its shorter.
Easier to maintain as code is shorter and easier to understand.
Easier to debug as code is shorter.
Work can be split up in a team to work on different subprograms at the same time.

Variable scopes

The differences between local and global variables:

Local variables are declared in subroutines.
Global variables are used throughout the entire program.

Advantages of using local variables:

Local variables are used when they are not needed throughout the entire program.
It uses memory only when needed.
It is harder to find errors in global as they can be accessed throughout the entire program.

Mr Suffar is developing an adding game. Write an algorithm to play this game. The rules for the game:

The game must have 5 players. (LOOP 5 TIMES).
For each player, the game asks the user to enter their name.
The player is then asked 8 addition questions for example: 5 + 6 , 7+7 , 8+10 (hint: another for loop is needed)
Each question asks the player to add together two random whole numbers between 1 and 10 inclusive.
If the user answer any question correctly, display “Correct” then add 1 to a score variable that starts with 0.
If the answer is incorrect display “Incorrect”
When each player finishes all 8 questions, their name is displayed on the screen and the number of correct answers is displayed in an appropriate format: for example: “Jones answered 8 questions correctly out of 8. Then add the name and the score to a 2D array called “players”. Which will be outputted once all players completed the game.
Store the name of each player and their score in a text file called “gamestats.txt”.

players= [ ["",""],["",""],["",""],["",""],["",""]]

578- A company wants to identify the length of time in seconds that sensor were activated in a day. Data for 2 of the days are shown in the table & array.

Using the array below, create a program that:

Asks the user for a date
If the date is in not in the array, it displays “error” and then repeats. If the date is in the array then it will do the following:
Calculates the total time the sensors were activated on that day
Store the total time for that day in a text file called “sensorstime.txt” and then outputs total time in an appropriate message including the date.

Example: Sensors were activated for 15 seconds on 15/03/2023

Use the array below to test your program.

sensors = [ ["15/10/2023",6],["15/10/2023",9],["16/10/2023",7],["16/10/2023",9] ]

Paste your code below:

Date	timeinseconds
15/10/2023	6
15/10/2023	9
16/10/2023	7
16/10/2023	9

An alarm has an algorithm that decides whether to sound the alarm by checking the data that is stored in the following three variables.
SystemArmed - example data: True
DoorSensorActive – example data: True
WindowSensorActive – example data: -True
The alarm will only sound when the SystemAlarm has been activated and one or both of the door and window sensors are activated. When the system needs to sound the alarm it calls the pre-written procedure SoundAlarm()
Write a program that asks the user the user to input True or False for each of the above variables (3 separate inputs needed) to check whether each is set to True or False depending on whether its active or not.
The program should check the data in the variables and calls SoundAlarm() when appropriate or displays “Alarm currently off”.
You must first create the SoundAlarm() procedure. The procedure must display “Warning!!” 5 times over 5 seconds. {Hint: Use import time and time.sleep(1) }

585. Coin flip game: In this program, you will create a flip the coin game where the user has to bet a specific amount, flip the coin and then win/lose the amount they bet depending if they get it right/wrong.

Give the user 1000 coins ($) by setting a variable to 1000.
Ask the user if they want to play the game, repeat the process using a while loop until the user enters NO.
Print the number of coins that they have.
Generate a random number between 1 and 2 and store it in a variable called coinroll.
Set the coin roll to heads if the coinroll is = 1 and to tails if the coin roll is = 2.
Ask the user how much they want to bet. Then use a while loop to repeat the question if they enter a bet that is higher than the number of coins ($) that they have.
Ask them if they want to pick heads or tails.
If they get it correct, give them the amount of coins they bet.
If they get it wrong, take away the amount of points they bet from the total coins they have that starts with 1000.
Ask the user if they want to play the game again. If they don’t say NO, then get them to play again unless they have 0 coins left.
