Exercises¶

1. Using string interpolation, fill out the parameters so that “I go to UM and I am in SI 306” is assigned to str1.

1.1 Using string interpolation, fill out the parameters so that ‘This book teaches students python.’ is assigned to info.

1.2 Below, we have provided a list of words. Use string formatting to produce the following string: “My favorite animals are elephants, giraffes, and zebras.” Save this string to the variable name animal_string.

2. Use string formatting to complete the string given. The blanks should correspond to variable name and breed.

2.1 Using string interpolation, assign the correct value to the variable names so that the value assigned to the variable sent is “Paul, Jackie, and Stephen have taught or are teaching this class.”

2.2 Below, we have created the variables course and school. Use string formatting to produce the following string: “I’m enrolled in SI 106 here at University of Michigan.” Save this string to the variable name final.

3. Provided is a list of tuples, the first is a country, the second is their medal count. Create a new list called medals using these tuples so that if the tuple was (‘USA’, 121), then what is added to medals is the string “USA won 121 medals”. Do so using string interpolation.

3.1 Provided is a list of tuples, the first is a name, the second is a city. Create a new list called user_info using these tuples so that if the tuple was (‘Ashley’, ‘Kalamazoo’), then what is added to user_info is the string “Ashley is from Kalamazoo”. Do so using string interpolation.

3.2 Below, we have provided a list of tuples that contain information about summer Olympic meets. Create a new list called olympics_info using these tuples so that if the tuple is (‘2016’, ‘Rio de Janeiro, Brazil’), then what is added to olympics_info is the string: “The 2016 Olympics were held in Rio de Janeiro, Brazil.” Do this by using string interpolation.

4. Write a function called pokemon that takes in a list of an integer and string. The integer is the level of the trainer and the string is where the trainer plays. If the player is level five or below, they have the most rattatas. If they are between level 6 and 10, they have the most zubats. If they are higher than level 10, they have the most eevees. Return the string “I’m level __ and I caught a bunch of __ in the __!” where the first blank is the player level, the second is the pokemon, and the third is the location where they play. For instance, if the inputted list is [2, “city”], the returned string should be “I’m level 2 and I caught a bunch of rattatas in the city!” Do this using string interpolation.

4.1 Write a function called data_mine that takes a tuple as input, and return a string using interpolation, depending on the second item in the tuple. The first item is a city name, the second is the weather condition. If the second item in the tuple has the value of ‘rain’, then it should also be cloudy. If the second item has the value of ‘sun’, then there should be blue skies. If the second item has the value of ‘snow’, then it should be cold. Return the string “In ___ there is ___ so it is ____.” or “In ____ there is ___ so there are _____.” (so for (‘Maz’, ‘rain’), we would return “In Maz there is rain so it is cloudy” (the same goes for snow), while for (‘Bieur’, ‘sun’), we would return “In Bieur there is sun so there are blue skies.”)

4.2 Write a function called grades that takes in a list with two elements, the first being a string (a person’s name) and the second being an integer (their grade on a test). If the grade is greater than or equal to 70, the function should return: “Congrats, [name], you passed the test with a [grade]!” If the grade is lower than 70, the function should return: “Sorry, [name], you failed the test with a [grade].”

5. The list of tuples, order, contains information about pizza orders. It contains information on whether or not the order is a pickup or delivery, how many pizzas were ordered, the kind of pizzas, and in how many minutes they need to be ready. Create a list called response that gives a response to each order. For a delivery, if the order input is (“delivery”, 1, “cheese”, 10), the response should be “Your 1 cheese pizza will be delivered in 10 minutes”. If the order is a pickup, the response should be “Come pick up your 1 cheese pizza in 10 minutes”.

5.1 Below, we have provided a list of tuples that contain information about customers’ product reviews on Amazon: the product, its rating, and customer name. Write a function called feedback that takes a tuple as input and returns a message to the customer based on their review. If the customer rated their product as an 8 or higher, feedback should return the following string: “[name], we’re happy to hear that you gave your new [product] a [rating] rating!” If the rating was below 8, feedback should return: “[name], we’re sorry to hear that your new [product] was not excellent.” Create a list called feedback_messages that contains a response to each customer below.
