Note: Avoid using class keywords like int, str, list, and dict as variable/parameter names.

1. Update Values in Dictionaries and Lists

x = [ [5,2,3], [10,8,9] ] students = [ {'first_name': 'Michael', 'last_name' : 'Jordan'}, {'first_name' : 'John', 'last_name' : 'Rosales'} ] sports_directory = { 'basketball' : ['Kobe', 'Jordan', 'James', 'Curry'], 'soccer' : ['Messi', 'Ronaldo', 'Rooney'] } z = [ {'x': 10, 'y': 20} ] 

1. Change the value 10 in x to 15. Once you're done, x should now be [ [5,2,3], [15,8,9] ].
2. Change the last_name of the first student from 'Jordan' to 'Bryant'
3. In the sports_directory, change 'Messi' to 'Andres'
4. Change the value 20 in z to 30

2. Iterate Through a List of Dictionaries

Create a function iterateDictionary(some_list) that, given a list of dictionaries, the function loops through each dictionary in the list and prints each key and the associated value. For example, given the following list:

students = [ {'first_name': 'Michael', 'last_name' : 'Jordan'}, {'first_name' : 'John', 'last_name' : 'Rosales'}, {'first_name' : 'Mark', 'last_name' : 'Guillen'}, {'first_name' : 'KB', 'last_name' : 'Tonel'} ] iterateDictionary(students) # should output: (it's okay if each key-value pair ends up on 2 separate lines; # bonus to get them to appear exactly as below!) first_name - Michael, last_name - Jordan first_name - John, last_name - Rosales first_name - Mark, last_name - Guillen first_name - KB, last_name - Tonel

3. Get Values From a List of Dictionaries

Create a function iterateDictionary2(key_name, some_list) that, given a list of dictionaries and a key name, the function prints the value stored in that key for each dictionary. For example, iterateDictionary2('first_name', students) should output:

Michael John Mark KB 

And iterateDictionary2('last_name', students) should output:

Jordan Rosales Guillen Tonel 

4. Iterate Through a Dictionary with List Values

Create a function printInfo(some_dict) that given a dictionary whose values are all lists, prints the name of each key along with the size of its list, and then prints the associated values within each key's list. For example:

dojo = { 'locations': ['San Jose', 'Seattle', 'Dallas', 'Chicago', 'Tulsa', 'DC', 'Burbank'], 'instructors': ['Michael', 'Amy', 'Eduardo', 'Josh', 'Graham', 'Patrick', 'Minh', 'Devon'] } printInfo(dojo) # output: 7 LOCATIONS San Jose Seattle Dallas Chicago Tulsa DC Burbank 8 INSTRUCTORS Michael Amy Eduardo Josh Graham Patrick Minh Devon
