Please do the following exercises and submit python files during the lab time.

Create a different file for every code. 

1. Fruit Basket:

A shopkeeper wants to record the weight of 4 fruit baskets.

a. Ask the user to enter 4 weights (kg).

b. Print the heaviest and lightest basket.

# Fruit Basket Weights

weights = []
for i in range(4):
    w = float(input(f"Enter weight of basket {i+1} (kg): "))
    weights.append(w)

print("Heaviest basket:", max(weights), "kg")
print("Lightest basket:", min(weights), "kg")

2. Movie Tickets: A cinema sells tickets for 25 SAR each.

a. Ask the user how many adults and how many children came.

b. Children pay half price.

c. Print the total cost.

# Movie Tickets Calculator

adult_tickets = int(input("Enter number of adults: "))
child_tickets = int(input("Enter number of children: "))

adult_price = 25
child_price = adult_price / 2

total = (adult_tickets * adult_price) + (child_tickets * child_price)

print("Total cost:", total, "SAR")

3. Exam Grades: Ask the user to enter 6 exam marks.

a. Store them in a list.

b. Print how many marks are passing (≥ 60) and how many are failing.

marks=[]
passing_counter=0
failing_counter=0
for mark in range(6):
    mark=int(input("enter the mark:"))
    marks.append(mark)
    if mark>=60:
        passing_counter+=1
    else: failing_counter+=1
print("number of passing marks: ",passing_counter)
print("number of failing marks: ",failing_counter)

4. Password Strength Checker:

Ask the user to enter a password.

a. If the password length < 6 → “Weak”

b. If it contains numbers and letters → “Strong”

c. Otherwise → “Medium”

password=input("enter the password:")
has_digit=False
has_letter=False
if len(password)<6:
    print("weak")
else:
    for p in password:
        if p.isdigit():
            has_digit=True
        if p.isalpha():
            has_letter=True
            
    if has_digit and has_letter:
      print("strong")
    else: print("Medium")

5. Cafeteria Menu: A cafeteria has a menu: ["tea", "coffee", "sandwich", "juice"].

a. Ask the user to order 3 items (input each one).

b. If an item is not in the menu, print “Not available”.

c. At the end, print the final order list.

menu = ["tea", "coffee", "sandwich", "juice"]
order = []

for i in range(3):
    item = input(f"Enter item {i+1}: ").lower()
    if item in menu:
        order.append(item)
    else:
        print("Not available")

print("Final order:", order)

6. Multiples Game: Ask the user for a number n.

a. Print all multiples of n from 1 to 100.

b. At the end, print how many multiples were found.

# Multiples Game

n = int(input("Enter a number: "))
multiples = []

for i in range(1, 101):
    if i % n == 0:
        multiples.append(i)

print("Multiples of", n, "from 1 to 100:", multiples)
print("Total multiples found:", len(multiples))

7. Parking Lot Fees: A parking lot charges 5 SAR per hour.

a. Ask the user how many hours 3 cars stayed.

b. Store the hours in a list.

c. For each car, print the fee (hours × 5).

d. At the end, print the total fee for all cars.

# Parking Lot Fees

hours = []
for i in range(3):
    h = float(input(f"Enter hours for car {i+1}: "))
    hours.append(h)

total_fee = 0
for i, h in enumerate(hours, start=1):
    fee = h * 5
    print(f"Car {i} fee: {fee} SAR")
    total_fee += fee

print("Total fee for all cars:", total_fee, "SAR")

8. Temperature Records: Ask the user to enter the temperature for 7 days.

a. Store in a list.

b. Print the average temperature.

c. Print how many days were above average.

# Temperature Records

temps = []
for i in range(7):
    t = float(input(f"Enter temperature for day {i+1}: "))
    temps.append(t)

avg_temp = sum(temps) / len(temps)
above_avg = sum(1 for t in temps if t > avg_temp)

print("Average temperature:", round(avg_temp, 2))
print("Days above average:", above_avg)

9. Student Class (with User Input):

Create a class `Student` with attributes `name` and `student_id`.

a. Constructor should initialize both.

b. Add getters, setters, and `__str__`.

c. Ask the user to enter data for 2 students, create objects, and print them.

# Student Class

class Student:
    def __init__(self, name, student_id):
        self.name = name
        self.student_id = student_id

    def get_name(self):
        return self.name

    def get_id(self):
        return self.student_id

    def set_name(self, name):
        self.name = name

    def set_id(self, student_id):
        self.student_id = student_id

    def __str__(self):
        return f"Student Name: {self.name}, ID: {self.student_id}"


students = []
for i in range(2):
    name = input(f"Enter name for student {i+1}: ")
    sid = input(f"Enter ID for {name}: ")
    s = Student(name, sid)
    students.append(s)

for s in students:
    print(s)

10. Book Class (with User Input):

Create a class `Book` with attributes `title`, `author`, and `pages`.

a. Constructor should initialize all attributes.

b. Add getters, setters, and `__str__`.

c. Ask the user to enter details for 2 books.

d. Print both books, and check if any book has more than 200 pages.

# Book Class

class Book:
    def __init__(self, title, author, pages):
        self.title = title
        self.author = author
        self.pages = pages

    def get_title(self):
        return self.title

    def get_author(self):
        return self.author

    def get_pages(self):
        return self.pages

    def set_title(self, title):
        self.title = title

    def set_author(self, author):
        self.author = author

    def set_pages(self, pages):
        self.pages = pages

    def __str__(self):
        return f"Book Title: {self.title}, Author: {self.author}, Pages: {self.pages}"


books = []
for i in range(2):
    title = input(f"Enter title for book {i+1}: ")
    author = input(f"Enter author for {title}: ")
    pages = int(input(f"Enter number of pages for {title}: "))
    b = Book(title, author, pages)
    books.append(b)

for b in books:
    print(b)
    if b.get_pages() > 200:
        print("This book has more than 200 pages.")
