What exactly does the delete operator do?

Answer the following questions for your initial discussion.   There are various functions that can be used for both strings and lists. Conduct research to locate several functions which might be useful. What do the functions do? Why would you use them? What is the syntax?

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…

What is a "foreach" loop?

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…

Complete the Swap() method in main.c to exchange the values of the num field of two Number struct objects, num1 and num2.

Assume the variable definitions references a dictionary.  Write an if statement that determines whether the key 'marsupial' exists in the dictionary.  If so, delete 'marsupial' and its associated value.   If the key is not in the dictionary, display a message indicating so.

As part of this assignment, the program that you will be writing will store current grades in a dictionary using course codes as keys and with values consisting of percent grades in lists. The main functions of this program are to print a student's gradebook, to drop the lowest grade in each course, print the student's gradebook again, drop the course with lowest average, and finally printing the student's gradebook again.  This program requires a main function and a custom value-returning function. In the main function, code these basic steps in this sequence (intermediate steps may be missing): start with an empty dictionary that represents a gradebook and then use a while loop to allow the input of course codes from the keyboard. End the while loop when the user presses enter without entering data.within the while loop:for each course entered, use a list comprehension to generate five random integers in the range of 70 through 100. These random integers in a list represent the…

Game of Hunt in C++ language   Create the 'Game of Hunt'.  The computer ‘hides’ the treasure at a random location in a 10x10 matrix. The user guesses the location by entering a row and column values. The game ends when the user locates the treasure or the treasure value is less than or equal to zero. Guesses in the wrong location will provide clues such as a compass direction or number of squares horizontally or vertically to the treasure. Using the random number generator, display one of the following in the board where the player made their guess: U#  Treasure is up ‘#’ on the vertical axis (where # represents an integer number). D# Treasure is down ‘#’ on the vertical axis (where # represents an integer number) || Treasure is in this row, not up or down from the guess location. -> Treasure is to the right. <- Treasure is to the left. -- Treasure is in the same column, not left or right. +$ Adds $50 to treasure and no $50 turn loss. -$ Subtracts…

Please show all of your workWrite and test the following function: def list_subtract(minuend, subtrahend): """ ------------------------------------------------------- Alters the contents of minuend so that it does not contain any values in subtrahend. i.e. the values in the first list that appear in the second list are removed from the first list. Use: list_subtract(minuend, subtrahend) ------------------------------------------------------- Parameters: minuend - a list of values (list) subtrahend - a list of values to not include in difference (list) Returns: None ------------------------------------------------------ """ Add the function to a PyDev module named functions.py. Test it from t01.py. Hint: you may use find_indexes in the function to solve the problem. The function does not ask for input and does no printing - that is done by your test program. Sample execution: list_subtract([5, 5, 4, 5], [5]) -> None minuend after: [4] Test the function with three different sets of…
