3. Write and test the following function: 1| def open_triangle(num_rows): Add the function to a PyDev module named functions.py. Test it from t03.py. open_triangle takes an integer parameter and prints a triangle of # characters with an empty center. Provide the function docstring (documentation) following the CP104 style. The function must use a for loop. The function does not ask for input. Sample execution: 1 | open_triangle(3) # # 1 open_triangle (8) ## # Test the function with three different sets of parameters. Partial testing: *#*## * * * * * * * #

Create a module called chemistry that contains the following three functions: elementName(symbol) This function accepts one string parameter. The symbol represents the name of a specific element on the periodic table. The function returns the name of the element (as string) of the specific element. For example, elementName(Na) returns Sodium. elementName(Li) return Lithium. Note: You are NOT allowed to use lists or any data types not yet covered in class. ionicCompound(e1, c1, e2, c2) This function accepts the chemical symbol and charge for two elements. The function should return the ionic compound created with these two elements. The subscripts should be reduced. ionicName(e1, e2) This function accepts the chemical symbols for two elements. Based on these two symbols the function should return an appropriate chemical name. ionicName(Mg, O) returns Magnesium Oxide. Create a Python program that uses the functions defined in your chemistry module to allow a user to create chemical…

LAB ASSIGNMENTS IMPORTANT: you should complete the PDP thinking process for each program. Turn in items: 1) book_list.py: you can adapt your Chapter 4 book_list.py Lab program. The program summarizes costs of a book list. It uses all of our standard mipo_ex features. In this version of the program you must use pylnputPlus functions to perform all the input validation and for the main() loop decision. Adjust your program to allow book prices to include $ and cents. Restrict individual book prices to $100 maxium. • Clearly document, with comments, your use of the pyip functions. This program summarizes a book liat. Enter the number of books that you need: Please enter a whole number: three Enter a number greater than 0: 3 Enter the name of book #1: The Mueller Report Enter cost of The Mueller Report, to the nearest dollar: Please enter a whole number: 18 Enter the name of book #2: Educated: A Memoir Enter cost of Educated: A Memoir, to the nearest dollar: Please enter a whole number: 24…

Non dynamic.arrays are allocated at runtime where dynamic arrays are allocated at compile time. True False Question 4 There are other ways to end a loop other than just the loop condition evaluating to false. True False

In c++ Write a for loop to print all elements in courseGrades, following each element with a space (including the last). Print forwards, th backwards End each loop with a newline. Ex If courseGrades (7, 9, 11, 10), print: 7 9 11 10 10 11 9 7 Hint Use two for loops. Second loop starts with i=NUM VALS-1. (Notes) Note: These activities may test code with different test values. This activity will perform two tests, both with a 4-element array (int courseGrades(4) See 'How to Use zyBooks Also note: If the submitted code tries to access an invalid array element, such as courseGrades[9] for a 4-element array, the test may generate strange results. Or the test may crash and report "Program end never reached", in which case the system doesn't print the test case that caused the reported message 32344345730rity? 2 using namespace std; 3 4 int main() { 5 6 7 8 9 10 11 12 13 14 const int NUM VALS-4; int courseGrades [NUM VALS]; int i; for (i = 0; i > courseGrades[1]; } y Your solution goes here Y

Computer Science csv file "/dsa/data/all_datasets/texas.csv" Task 6: Write a function "county_locator" that allows a user to enter in a name of a spatial data frame and a county name and have a map generated that shows the location of that county with respect to other counties (by using different colors and/or symbols). Hint: function(); $county ==; plot(); add=TRUE.

Write a function calculate_expression(values) that calculates and returns the value of the following expression: ((angle - 34) ** (1./a)) / (vol ** b) The function receives as input a dictionary containing the values of the parameters (a, b, vol, angle). The string name of the parameter is the key and the associated number is the value. The result must be rounded to three digits after the comma.
