Each name should be followed by a hard return (do not store them in a list). Main Function. Write a program where the user enters a name. Using the read function, check to see if the name is in the text document. If it is, respond back to the user the name is found within the list. Read Function. The read function should return the contents of the text document as a list. Write Function. The write function should take the list and override the file with the new names list in reverse alphabetical order with a hard return after each name.arrow_forwardSlot Machine SimulationA slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money that the slot machine dispenses back to the user. Create a program that simulates a slot machine. When the program runs, it should do the following: Asks the user to enter the amount of money he or she wants to enter into the slot machine. Instead of displaying images, the program will randomly select a word from the following list: Cherries, Oranges, Plums, Bells, Melons, Bars To select a word, the program can generate a random number in the range of 0 through 5. If the number is 0, the selected word is Cherries; if the number is 1, the selected word is Oranges; and so forth. The program should randomly select a word from this list three times and display all three of the words. If none of the randomly selected words match, the…arrow_forward
- C# language MORSE CODE CONVERTERDesign a program that asks the user to enter a string and thenconverts that string to Morse code. Morse code is a code whereeach letter of the English alphabet, each digit, and variouspunctuation characters are represented by a series of dots anddashes. Table 8-9 shows part of the code. Needs to be two labels, two text boxes and click button for conversionarrow_forwardLearning Objectives: Python Programming Use loop over a stringReplace characters within a stringFunction (declaration and call)Write code in modular formInstructions Create a function only_chars that takes the line of text and returns the text line excluding the spaces, periods, exclamation points, or commas. Create a program that will read the input line, use the function, and then print the line, without spaces, periods, exclamation marks, or commas and their length. Ex: If the input is: Listen, Mr. Jones, calm down. the output is: ListenMrJonescalmdown21Do not forget if __name__ == "__main__" section!arrow_forwardIn C # Assume a file named Student.txt contains a list of student names.

- Write code that does the following: Opens a file named NumberList.txt, uses a loop to write the numbers 1 through 100 to the file, and then closes the file. Opens the NumberList.txt file and reads all of the numbers from the file and displays them, and then closes the file. Opens the NumberList.txt file and reads all of the numbers from the file, calculate the sum of these numbers and displays their total. Opens a file named NumberList.txt for writing, but does not erase the contents of the file if it already exists.arrow_forwardA ______ value is a special value that is used to terminate a loop when a set of data is being entered.

When the loop finishes, the program should display the time of their fastest lap, the time of their slowest lap, and their average lap time.arrow_forward
- Geometric Progression Printer As you might recall, a Geometric Progression (or GP) is a sequence of elements in which the next number in the sequence is obtained by multiplying the previous number by the common ratio. The next number in the sequence is obtained by using this formula: a_na_1* r(n-1) While the sum of all numbers in the sequence is obtained using any of these formulae: If r 1, sum = a* n If r != 1 and r> 1, sum= a[(r¹-1)/(r - 1)] If r != 1 and r < 1, sum = a[(1 - r¹)/(1-r)] where a n = next number in the sequence, a_1 = first number in the sequence, r = common ratio, n = number of terms Your task is to write a Python program that 1. Accepts the necessary inputs from the user, i.e., start value (a_1), common ratio (r), and number of generate to generate (n). 2. Generates the Geometric Progression (GP) sequence starting from a_1 to n. 3. Prints out the GP HORIZONTALLY not VERTICALLY, e.g. 3, 9, 27, 81, 243, 729 .... 4. Calculates the sum of all numbers in the GP sequence 5.…arrow_forwardGroup 2/12 Problem – Population Create an application that predicts the approximate size of a population of organisms. The application should use textboxes to allow the user to enter the starting number of organisms, the average daily population increase (as a percentage), and the number of days the organisms will be left to multiply. Use a ListBox to display the population size for each day of the simulation. If the user clicks the Save button, save the current prediction to a file.
