  1. The code below takes the list of country, country, and searches to see if it is in the dictionary gold which shows some countries who won gold during the Olympics. However, this code currently does not work. Correctly add try/except clause in the code so that it will correctly populate the list, country_gold, with either the number of golds won or the string “Did not get gold”.

1.1 Provided is a buggy for loop that tries to accumulate some values out of some dictionaries. Insert a try/except so that the code passes.

1.2 Below, we have provided a list of tuples that consist of student names, final exam scores, and whether or not they will pass the class. For some students, the tuple does not have a third element because it is unknown whether or not they will pass. Currently, the for loop does not work. Add a try/except clause so the code runs without an error - if there is no third element in the tuple, no changes should be made to the dictionary.

  1. The list, numb, contains integers. Write code that populates the list remainder with the remainder of 36 divided by each number in numb. For example, the first element should be 0, because 36/6 has no remainder. If there is an error, have the string “Error” appear in the remainder.

2.1 Provided is buggy code, insert a try/except so that the code passes.

2.2 Below, we have provided code that does not run. Add a try/except clause so the code runs without errors. If an element is not able to undergo the addition operation, the string ‘Error’ should be appended to plus_four.

  1. The code below assigns the 5th letter of each word in food to the new list fifth. However, the code currently produces errors. Insert a try/except clause that will allow the code to run and produce of list of the 5th letter in each word. If the word is not long enough, it should not print anything out. Note: The pass statement is a null operation; nothing will happen when it executes.

3.1 Write code so that the buggy code provided works using a try/except. When the codes does not work in the try, have it append to the list attempt the string “Error”

3.2 The following code tries to append the third element of each list in conts to the new list third_countries. Currently, the code does not work. Add a try/except clause so the code runs without errors, and the string ‘Continent does not have 3 countries’ is appended to countries instead of producing an error.

  1. The buggy code below prints out the value of the sport in the list sport. Use try/except so that the code will run properly. If the sport is not in the dictionary, ppl_play, add it in with the value of 1.

4.1 Provided is a buggy for loop that tries to accumulate some values out of some dictionaries. Insert a try/except so that the code passes. If the key is not there, initialize it in the dictionary and set the value to zero.

4.2 Below, we have provided buggy code. Add a try/except clause so the code runs without errors. If a blog post didn’t get any likes, a ‘Likes’ key should be added to that dictionary with a value of 0.
