Note: I am using python I have a 2d list called data as the input: data = [ [2,4,3], [8,6,4], [2,0,17], [8,0,17], [8,3,7] ] I need to count how many times the first number of each list repeats and then store the information in a dictionary where the number is the key and the number of times it repeats is the value Output

Please complete on Python   Write a program that keeps a dictionary in which both keys and values are strings, names of students and their courses grades. Prompt the user of the program to add or remove students, to modify grades, or to print all grades. The printout should be sorted by name and formatted like this: <br>Carl: B+ <br>Joe: C <br>Sarah: A <br>Francine: A

python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.

Put the following code in a main.py file and a module.py file. Define the names sort, list_max and sum_of_list after putting the code into a main file and a module file   #predefined modules import random import math #function to sort the list in ascending order def sort(x):     #predefined function sort()     x.sort()     #print the sorted list     print("\nSorted list is: ",str(x)) #function to find the sum of list elements def sum_of_list(x):     #predefined function sum()     Sum=sum(x)     #return the sum of list elements     return Sum #function to list the maximum from the list def list_max(x):     #predefined function max()     maximum=max(x)     #return maximum     return maximum #function to test the above three function def main():     #set a flag variable     flag=True     #create a list     list1=list()     #initialize the list element by using randrange() predefined function of random module     list1=[random.randrange(1, 50, 1) for i in range(0,7)]     #print the…

Write a python program that takes two lists, merges thetwo lists, sorts the resulting list, and then finds the median of theelements in the two lists. You cannot use python build-in sort() function #todo#You can use math functions like math.floor to help the calculationimport math #todo#You can use math functions like math.floor to help the calculation import math def task7(list_in_1, list_in_2):  # YOUR CODE HERE                return median please use these variables no print function please

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…

Write the code (Python) necessary to sum the elements of an list named: myLstAssume the list myLst has already been created and initializedAssume the constant SIZE has already been created and initialized with the number of elements in the myLst list.Complete the following tasks:Using a loop of your choice,OOutput each element of the list myLst•Calculate the sum of the elements of the list myLst. Create any variables necessary to complete this task.Output the string "Sum is: " followed by the actual sumNote: Only submit the code necessary to complete this task. Do not create myLst or SIZE, as you are to assume they have already beencreated and assigned values.

Word frequencies (dictionaries) Implement the build_dictionary() function to build a word frequency dictionary from a list of words. Ex: If the words list is: ["hey", "hi", "Mark", "hi", "mark"] the dictionary returned from calling build_dictionary(words) is: {'hey': 1, 'hi': 2, 'Mark': 1, 'mark': 1}   half answered: code: def build_dictionary(words):# The frequencies dictionary will be built with your code below.# Each key is a word string and the corresponding value is an integer # indicating that word's frequenc # The following code asks for input, splits the input into a word list, # calls build_dictionary(), and displays the contents sorted by key.if __name__ == '__main__':words = input().split()your_dictionary = build_dictionary(words)sorted_keys = sorted(your_dictionary.keys())for key in sorted_keys:print(key + ': ' + str(your_dictionary[key]))
