Your program should prompt the user to enter names and salaries from the user. Create a dictionary called information which should be initialized by the values from the two lists that you created above. Your program should pass this dictionary to a function named insights which would calculate and print the names and salaries for each employee. Before printing the salary, your function should multiply the salary by a random number and then print it. [26] For example, name = Employee01, salary = 100 new_salary = salary * random number between 1 and 10
python exercise: Write a Python function called get_top_students that takes the list of dictionaries as input and returns a dictionary containing the name and GPA of the top two students in the list. Each dictionary has the following keys: "name", "age", "major", and "gpa".
Each function deals with null terminated C-strings. You can assume that any char array passed into the functions will contain valid, null-terminated data. Your functions must have the signatures listed below. This function returns the index in string s where the substring can first be found. For example if s is “Skyscraper” and substring is “ysc” the function would return 2. It should return -1 if the substring does not appear in the string. int findSubstring(char *s, char substring[])
Task 01 Write a function that takes a dictionary as a parameter. The dictionary holds student names as keys and their mid-term marks in the python course as values. Your function should get the student name corresponding to the minimum and maximum mark achieved by the student and return it to the function call. Then, finally prints the returned statement after the function call. Sample Input: {'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 } Function Call: function_name({'Samin': 25, 'Lily': 28,'Akib': 17,'Salma': 22, 'Imon': 20 }) Sample Output: Highest scorer: Lily Lowest scorer: Akib Sample Input: {"A":60,"B":30,"P":2, "R":8, "S":33, "T":88} Function Call: function_name({"A":60,"B":30,"P":2, "R":8, "S":33, "T":88}) Sample Output: Highest scorer: T Lowest scorer: P
3. lookup_friends_heights This function takes a friends database (a list of dictionaries, like the previous functions) and a list of friends names, and it returns a list of heights for the specified friends. If a given friend's name is not present in the friends database, we put a None in the corresponding slot. We assume that there will be at most one friend with a given name in the list. You may want to use nested for-loops for this function. Sample calls should look like this. >>> lookup_friends_heights([{"name":"todd","height":170},{"name": "sarah", "height":165},{"name":"dweezil", "height":175}], ["dweezil", "sarah"]) [175, 165] >>> lookup_friends_heights([{"name": "todd","height":170},{"name": "sarah","height":165},{"name": "dweezil", "height":175}], %3D ["sarah", "elíza", "dweezil"]) [165, None, 175]

Overview This is a review assignment where you will use multiple tools you have picked up so far throughout the course. If you're confused about how to do something make sure you look back at earlier assignments. In this program you will start by declaring an empty dictionary named population_dict. Then you will use a while-loop to prompt a user for a series of cities and their populations, storing the input in population_dict). After this you will prompt the user to decide what is the maximum population for a city to be considers a small down. Finally, you will open a file called populationdata.txt where you will write the results. Expected Output Example of standard out (the console): What is next city? (enter q to quit) Long Beach What is the population of Long Beach? 362000 What is next city? (enter q to quit) Los Angeles What is the population of Los Angeles? 382000000 What is next city? (enter q to quit) San Diego What is the population of San Diego? 136000000 What is next city?…
Median Function – In statistics, the median of a set of values is the value that lies in the middle when the values are arranged in sorted order. If the set has an even number of values, the median is the average of the two middle values. Your program should start with two arrays of integers containing the following values: Even numbered array: 17 32 45 68 99 101 67 89 22 27 Odd numbered array: 17 32 45 68 99 101 67 89 22 Using a sort function of your choice, first sort the arrays. NOTE: you may use the Standard Template Library sort function or your own sort function. Then, write a function that determines the median of a sorted array. The function should take an array of numbers and an integer indicating the size of the array and return the median of the values in the array. The same function should be called twice – once for the even array and once for the odd array. Your program should also have a printArray function that can be used to print the sorted array. (It…
Tails Function Purpose: Produce a new column-based ( e.g. dict[str, list[str]] ) table with only the first N (a parameter) rows of data for each column. * Function name: Tails Parameters: 1. dict[str, list[str]] - a column-based table of data that_will not be mutated_ 2. int - The number of "rows" to include in the resulting list * Return type: dict[str, list[str]] Implementation strategy: 1. Establish an empty dictionary that will serve as the returned dictionary this function is building up. 2. Loop through each of the columns in the first row of the table given as a parameter. 1. Inside of the loop, establish an empty list to store each of the first N values in the column. 2. Loop through the first N items of the table's column, 1. Appending each item to the previously list established in step 2.1. 3. Assign the produced list of column values to the dictionary established in step 1. 3. Return the dictionary.
Write a function that use array (y) to print the result in the figure. Then write only the call statement to call the function. y = -3 4 0 -1 5 -6 2 8 10 -4 Location of negative numbers: 0 --> -3 3 --> -1 5 --> -6 9 --> -4
a C++ program that creates a two-dimensional integer array (4x3) initialized with user given data. The program should have the following functions: • Print the sum of all values in the array. • Print the average of all the values in the array. • Take row number from user and print the sum of the values in that specified row.(use loop and no if statement) • Take column number from user and print the sum of the values in that specified column.(use loop and no if statement)
