Python Script Variable and Conditional Review

June 14, 2022

In this activity, you will review variable declaration and conditionals.

Starter file

# Create a list called 'farm' with the elements "pig", "cow", "chicken", "dog", "horse", "sheep".


# Write an if statement that prints the string "RWAR!" if the first element of farm is NOT "Godzilla".

# Write an else if statement that prints the string "SCREECH!" if the last element of farm is "Mothra".

# Else, print the string "This animal is neither Godzilla nor Mothra!".


# Declare a variable named 'dog' with a string of "Spot".

# Declare 3 variables `cat`, `city`, `car` without assigning them values.


# Assign the string "Farley" to `cat`.


# Assign the string "San Francisco" to `city`.


# Assign the string "Prius" to `car`.


# Using string concatenation, print out the sentence "See Spot run!".


# Using string concatenation, print out the sentence "I drive Farley around San Francisco in my Prius".


# Declare a variable budget and assign it a value of 5000.


# Declare a variable rent_cost and assign it a value of 1500.


# Declare a variable utilities_cost and assign it a value of 150.


# Declare a variable food_cost and assign it a value of 250.


# Declare a variable transportation_cost and assign it a value of 350.


# Declare a variable computer_cost and assign it a value of 2000.


# Declare a variable called total_cost that takes the sum of all costs above (excluding budget).


# Write an if statement that checks whether the sum of all our costs is within the budget.
# If so, print "You're total cost is " concatentated with the `total_cost` variable.
# Else, print "You're over budget by " concatenated with the difference between `budget` and `total_cost`.


# Write an if statement that checks whether the rent_cost is larger than the sum of the `utilities_cost`, `food_cost`,
# and `transportation_cost`. If so, print a string that says "The rent is too damn high!".
# Else, print a string that says "Ahhh just right!"

Instructions

Open the starter file and perform the following:

Create a list called farm with the elements “pig”, “cow”, “chicken”, “dog”, “horse”, “sheep”.
Write an if statement that prints the string “RWAR!” if the first element of farm is NOT “Godzilla”.
Write an else-if statement that prints the string “SCREECH!” if the last element of farm is “Mothra”.
Else, print the string “This animal is neither Godzilla nor Mothra!”
Declare a variable named dog with a string of “Spot”.
Declare 3 variables, cat, city, and car, without assigning them values.
Assign the string “Farley” to cat.
Assign the string “San Francisco” to city.
Assign the string “Prius” to car.
Using string concatenation, print out the sentence “See Spot run!”
Using string concatenation, print out the sentence “I drive Farley around San Francisco in my Prius”.
Declare a variable budget and assign it a value of 5000.
Declare a variable rent_cost and assign it a value of 1500.
Declare a variable utilities_cost and assign it a value of 150.
Declare a variable food_cost and assign it a value of 250.
Declare a variable transportation_cost and assign it a value of 350.
Declare a variable computer_cost and assign it a value of 2000.
Declare a variable total_cost that takes the sum of all costs above (excluding budget).
Write an if statement that checks whether the sum of all the costs is within the budget.
- If so, print “Your total cost is ” concatentated with the total_cost variable.
- Else, print “You’re over budget by ” concatenated with the difference between budget and total_cost.
Write an if statement that checks whether the rent_cost is larger than the sum of the utilities_cost, food_cost, and transportation_cost.
- If so, print a string that says “The rent is too damn high!”
- Else, print a string that says “Ahhh just right!”

Solution

# Create a list called 'farm' with the elements "pig", "cow", "chicken", "dog", "horse", "sheep".
farm = ["pig", "cow", "chicken", "dog", "horse", "sheep"]

# Write an if statement that prints the string "RWAR!" if the first element of farm is NOT "Godzilla".
if farm[0] == "Godzilla":
    print("RWAR!")
# Write an else if statement that prints the string "SCREECH!" if the last element of farm is "Mothra".
elif farm[-1] == "Mothra":
    print("SCREECH!")
# Else, print the string "This animal is neither Godzilla nor Mothra!".
else:
    print("This animal is neither Godzilla nor Mothra!")

# Declare a variable named 'dog' with a string of "Spot".
dog = "Spot"

# Declare 3 variables `cat`, `city`, `car` without assigning them values.
cat = ""
city = ""
car = ""

# Assign the string "Farley" to `cat`.
cat = "Farley"

# Assign the string "San Francisco" to `city`.
city = "San Francisco"

# Assign the string "Prius" to `car`.
car = "Prius"

# Using string concatenation, print out the sentence "See Spot run!".
print(f"See {dog} run!")

# Using string concatenation, print out the sentence "I drive Farley around San Francisco in my Prius".
print(f"I drive {cat} around {city} in my {car}")

# Declare a variable budget and assign it a value of 5000.
budget = 5000

# Declare a variable rent_cost and assign it a value of 1500.
rent_cost = 1500

# Declare a variable utilities_cost and assign it a value of 150.
utilities_cost = 150

# Declare a variable food_cost and assign it a value of 250.
food_cost = 250

# Declare a variable transportation_cost and assign it a value of 350.
transportation_cost = 350

# Declare a variable computer_cost and assign it a value of 2000.
computer_cost = 2000

# Declare a variable called total_cost that takes the sum of all costs above (excluding budget).
total_cost = rent_cost + utilities_cost + food_cost + transportation_cost + computer_cost

# Write an if statement that checks whether the sum of all our costs is within the budget.
# If so, print "You're total cost is " concatentated with the `total_cost` variable.
# Else, print "You're over budget by " concatenated with the difference between `budget` and `total_cost`.
if total_cost < budget:
    print(f"You're total cost is {total_cost}")
else:
    print(f"You're over budget by {total_cost - budget}")

# Write an if statement that checks whether the rent_cost is larger than the sum of the `utilities_cost`, `food_cost`,
# and `transportation_cost`. If so, print a string that says "The rent is too damn high!".
# Else, print a string that says "Ahhh just right!"
if rent_cost > (utilities_cost + food_cost + transportation_cost):
    print("The rent is too damn high!")
