get_top_regions() that takes three input parameters; the 2-D list (similar to the database), the dictionary that stores information of all regions, and a non-zero positive integer x. This function returns a new dictionary that contains the information of top-x regions in terms of the total number of hospitalization cases recorded in these regions. That means these top-x regions have the largest numbers of hospitalization cases. Each {key:value} pair in this resulting dictionary stores the name of a top region as the key and the value is the total number of hospitalization cases reported in this region. The result does not need to be sorted, the regions of the resulting dictionary can appear in any order as long as the top-x regions have been identified correctly. If the value of x is less than 1, or more than the total number of unique regions, your function should print a message informing the user and return an empty dictionary. See sample outputs below. >>> topx_regions…
Python question, need some help
True/False Select true or false for the statements below. Explain your answers if you like to receive partial credit. 3) Which of the following is true about the insertBeforeCurrent function for a CircularLinked List (CLL) like you did in programming exercise 1?a. If the CLL is empty, you need to create the new node, set it to current, andhave its next pointer refer to itselfb. The worst case performance of the function is O(n)c. If you insert a new element with the same data value as the current node, theperformance improves to O(log n)
What will be displayed after the following code executes? (Note: the order of the display of entries in a dictionary are not in a specific order.)
Code the following directions in python. 1.Assume the variable dct references a dictionary. Write an if statement that determines whether the key 'Jim' exists in the dictionary. If so, delete 'Jim' and its associated value. 2.Write code to create a set with the following integers as members: 10, 20, 30, and 40. 3.Assume each of the variables set1 and set2 references a set. Write code that creates another set containing all the elements of set1 and set2, and assigns the resulting set to the variable set3.
Read strings from input until 'stop' is read. For each string read: If the string is a key in dictionary patients_record, delete the key from patients_record and output the string followed by ' deleted'. Otherwise, output the string followed by ' not a key'.
This code is a part of a C dictionary. Please write the code for the below requirements. dict_get Next, you will implement: char* dict_get (const dict_t* dict, const char* key); This function goes through the list given by dict. If you use the above structure, this means starting at el = dict->head and checking each time whether the key at el is key; if it is not, we set el = el->next, until either key is found, or we reach el == NULL. To compare key with el->key, we need to compare one by one each character in key with those in el->key. Remember that strings in C are just pointers (memory addresses) to the first character in the string, so comparing el->key == key will not do what you want. So how do you even get the length of a string s? You would start at memory location s and advance as long as the byte at s (i.e. *s) is not the end-of-string marker (\0, the NULL character). This can get a bit messy, so luckily, you are allowed to use the string comparison…
Write code that iterates through a dictionary represented by the variable my_dict and prints any values (not keys!) associated with keys beginning with the letter "k" (lowercase).
Write a program that creates a dictionary containing Canadian provinces' abbreviations as the keys (e.g., 'on') and their long format as the values (e.g., 'Ontario'). Use the internet to get a list of provinces and their abbreviations. The program should then randomly quiz the user by displaying the abbreviation of the province and asking the user to enter the extended format for the abbreviation. The program should keep count of the number of correct and incorrect responses.
In python make a function with the parameter of a dict[str, str] the function will simply invert the dictionary do not use .get, .item, .values, or import builtins If you encounter more than one of the same key when trying to invert the key and value, raise a keyerror for example ['john': 'white', 'garcia': 'white'], should trigger the raise KeyError call
This section has been set as optional by your instructor. OBJECTIVE: Write a program in Python that prints the middle value of a dictionary's values, using test_dict from the test_data.py module. NOTE: test_dict is created & imported from the module test_data.py into main.py Example 1: test dict = {'a':1,'b':9,'c':2,'d':5} prints 5 Example 2: test_dict = {'b':9,'d':5} prints 5 Hint: You may(or may not) find the following function useful: list.sort() which sorts the elements in a list. Note: the result is automatically stored in the original list, and return value from the function is None Туре list = [1, 2,3,2,1] After calling: list = [1,1,2,2,3] list.sort(), 339336.2266020 x3zgy7 LAB 13.11.1: Middlest Value (Structured Types) АCTIVITY 0/11 File is marked as read only Current file: test_data.py 1 #This module creates the test_dict to be used in main.py 2 #Reads input values from the user & places them into test_dict 3 dict_size = int(input()) #Stores the desired size of test_dict. 4…
given dictionaries, d1 and d2, create a new dictionary with the following property. For each entry(a,b) in d1, if a is not a key of d2 then add (a,b) to the new dictionary. For each entry (a,b) in d2, if a is not a key of d1 then add (a,b) to the new dictionary. For example, if d1 is {2:3, 8:19, 6:4, 5:12} and d2 is {2:5, 4:3, 3:9}, then the new dictionary should be {8:19, 6,4, 5:12, 4:3, 3:9}. using puthon
