Day 3 - Beginner - Control Flow and Logical Operators

30. Control Flow with if | else and Conditional Operators.py

print("Welcome to the rollercoaster!")
height = int(input("What is your height in cm? "))

if height >= 120:
    print("You can ride the rollercoaster!")
else:
    print("Sorry, you have to grow taller before you can ride. ")

31. [Interactive Coding Exercise] Odd or Even? Introducing the Modulo.py

# Which number do you want to check?
number = int(input())

# If the number can be divided by 2 with 0 remainder.
if number % 2 == 0:
    print("This is an even number.")
# Otherwise (number cannot be divided by 2 with 0 remainder).
else:
    print("This is an odd number.")

32. Nested if statements and elif statements.py

print("Welcome to the rollercoaster!")
height = int(input("What is your height in cm? "))

if height >= 120:
    print("You can ride the rollercoaster!")
    age = int(input("What is your age? "))
    if age < 12:
        print("Please pay $5.")
    elif age <= 18:
        print("Please pay $7.")
    else:
        print("Please pay $12.")
else:
    print("Sorry, you have to grow taller before you can ride.")

33. [Interactive Coding Exercise] BMI 2.0.py

print("Welcome to the rollercoaster!")
height = float(input("What is your height in meters? "))  # e.g., 1.55
weight = int(input("What is your weight in kilograms? "))  # e.g., 72

# Calculate BMI
bmi = weight / (height * height)

# Categorize BMI
if bmi < 18.5:
    print(f"Your BMI is {bmi:.2f}, you are underweight.")
elif bmi < 25:
    print(f"Your BMI is {bmi:.2f}, you have a normal weight.")
elif bmi < 30:
    print(f"Your BMI is {bmi:.2f}, you are slightly overweight.")
elif bmi < 35:
    print(f"Your BMI is {bmi:.2f}, you are obese.")
else:
    print(f"Your BMI is {bmi:.2f}, you are clinically obese.")

34. [Interactive Coding Exercise] Leap Year.py

# Which year do you want to check?
year = int(input())

if year % 4 == 0:
    if year % 100 == 0:
        if year % 400 == 0:
            print("Leap year")
        else:
            print("Not leap year")
    else:
        print("Leap year")
else:
    print("Not leap year")

35. Multiple If Statements in Succession.py

print("Welcome to the rollercoaster!")
height = int(input("What is your height in cm? "))
bill = 0

if height >= 120:
  print("You can ride the rollercoaster!")
  age = int(input("What is your age? "))
  if age < 12:
    bill = 5
    print("Child tickets are $5.")
  elif age <= 18:
    bill = 7
    print("Youth tickets are $7.")
  else:
    bill = 12
    print("Adult tickets are $12.")
  
  wants_photo = input("Do you want a photo taken? Y or N. ")
  if wants_photo == "Y":
    bill += 3
  
  print(f"Your final bill is ${bill}")

else:
  print("Sorry, you have to grow taller before you can ride.")

36. [Interactive Coding Exercise] Pizza Order Practice.py

print("Thank you for choosing Python Pizza Deliveries!")
size = input()  # What size pizza do you want? "S", "M", or "L"
add_pepperoni = input()  # Do you want pepperoni? "Y" or "N"
extra_cheese = input()  # Do you want extra cheese? "Y" or "N"

# Your code below this line 👇
bill = 0
if size == "S":
  bill += 15
elif size == "M":
  bill += 20
else:
  bill += 25

if add_pepperoni == "Y":
  if size == "S":
    bill += 2
  else:
    bill += 3

if extra_cheese == "Y":
  bill += 1

print(f"Your final bill is: ${bill}.")

38. [Interactive Coding Exercise] Love Calculator.py

print("The Love Calculator is calculating your score...")
name1 = input()  # What is your name?
name2 = input()  # What is their name?
# Your code below this line 👇
combined_names = name1 + name2
lower_names = combined_names.lower()
t = lower_names.count("t")
r = lower_names.count("r")
u = lower_names.count("u")
e = lower_names.count("e")
first_digit = t + r + u + e

l = lower_names.count("l")
o = lower_names.count("o")
v = lower_names.count("v")
e = lower_names.count("e")
second_digit = l + o + v + e

score = int(str(first_digit) + str(second_digit))
if (score < 10) or (score > 90):
  print(f"Your score is {score}, you go together like coke and mentos.")
elif (score >= 40) and (score <= 50):
  print(f"Your score is {score}, you are alright together.")
else:
  print(f"Your score is {score}.")
