Can you Tell What the Following Program Does?

It uses Almost All of the Topics We Studies in Python Including:

• Lists
• Functions
• Loops including for and While
• Conditionals/If Statements
• Importing Modules
• User Input
• Variables
• Print Statements

import random  # This is the module we'll use

def get_random_number():
    """Generates a random number between 1 and 10."""
    return random.randint(1, 10)

def get_user_guess():
    """Prompts the user for a guess and returns it as an integer."""
    guess = input("Enter your guess (1-10): ")
    return int(guess)

def play_game():
    """Main game logic."""
    number_to_guess = get_random_number()
    guess = None
    attempts = 0
    guesses = []

    print("Welcome to the Guess the Number Game!")
    print("Try to guess the number between 1 and 10.")

    while guess != number_to_guess:
        guess = get_user_guess()
        guesses.append(guess)
        attempts += 1

        if guess < number_to_guess:
            print("Too low!")
        elif guess > number_to_guess:
            print("Too high!")
        else:
            print(f"Correct! The number was {number_to_guess}.")
            print(f"It took you {attempts} attempts.")

    print("\nYour guesses were:")
    for g in guesses:
        print(g)

# Run the game

Pseudocode and Algorithms

What is an Algorithm?

An algorithm is a step-by-step set of instructions for solving a problem or completing a task.

An algorithm is a recipe for solving a problem.

How would you find the largest number given a list of numbers?

def find_max(num_list):
    max_num = num_list[0]
    for num in num_list:
        if num > max_num:
            max_num = num
    return max_num    

Pseudocode

What is Pseudocode

Pseudocode is a way to describe an algorithm using plain, structured language that looks like code — but isn't meant to run on a computer.

Key Points About Pseudocode

• It's not real code (won't run in Python, Java, etc.)
• It uses simple, human-readable language
• Helps plan out the logic of a program before coding
• Focuses on the what and how, not the syntax

Pseudocode to find Max Number

START
SET max TO first number in the list
FOR each number in the list
    IF number > max THEN
        SET max TO number
    ENDIF
ENDFOR
PRINT max
END

Pseudocode Rules

There is no strict standard, but it is usually

• Use indentation to show structure (like loops and conditionals)
• Use keywords like IF, THEN, ELSE, FOR, WHILE, etc.
• Keep it simple and clear
• Avoid specific programming language syntax

Pseudocode Examples

Check if Number is Even or Odd

START
INPUT number
IF number MOD 2 = 0 THEN
    PRINT "Even"
ELSE
    PRINT "Odd"
ENDIF
END

Sum 2 Numbers

START
INPUT num1, num2
SET sum TO num1 + num2
PRINT sum
END

Print Numbers 1 to 5

START
FOR i FROM 1 TO 5
    PRINT i
ENDFOR
END

Count how many times a number appears in a list

START
INPUT list of numbers
INPUT target number
SET count TO 0
FOR each number IN list
    IF number = target THEN
        INCREMENT count BY 1
    ENDIF
ENDFOR
PRINT count
END
