please code in python The data for this product is stored in the text file named GasPrice.txt [The image]. The file contains the weekly average prices for a gallon of gas in the United States, beginning on April 5th, 1993, and ending on August 26th, 3013. The following is a sample of the first few lines of the data file. Each line in the file contains the average price for a gallon of gas on a specific date. Each line is formatted in this way: MM-DD-YYYY:Price Where MM is the two-digit moth, DD is two-digit day, and YYYY is the four-digit year. Price is the average price per gallon of gas on the specific day. For this project, you are to develop one or more programs that read the data from the data file, and perform these tasks: Average Price Per Year: Calculate the average price of gas per year, for each year in the file. Average Price Per Month: Calculate the average price for each month in the file. Highest and Lowest Prices Per Year: For each year in the data file,…

A program stores the prime numbersin a file named PrimeNumbers.dat. Write a program that finds the numberof prime numbers that are less than or equal to 12, 120, 1,200, 12,000,100,000, 1,200,000, 12,000,000, 120,000,000, 1,200,000,000, and12,000,000,000. Your program should read the data from PrimeNumbers.dat.
Code in Python: 10 users were asked to select from four options (A, B, C and D). Their responses are stored in the variable x below. x = pd.Series(["A" , "B", "A", "A", "D", "C", "A", "C", "A", "A"]) Use the data in x to plot a pie chart representing the counts for each of the 4 options. This can be done by: - Counting the number of occurrences of each option and storing it into a DataFrame. - Invoking the plot method in Pandas with pie option on the DataFrame, indicating that your y value is the counts column.
I want to read the numbers from random_number.txt and then display the number and display total of the number and the number of random number read from the file and the average of this number
Sorted telephone numbers are given as input of data from the monitor. Determine and display the gap(telephone numbers) between the telephone numbers. Gap means, telephone numbers which are not given to anybody yet. For example, if the given telephone numbers are given as 36687821 36687825 36687830 36687831 36687835 EOF Output will be as follows The gap between the telephone numbers 36687821-36687825 are 36687822, 36687823, 36687824 The gap between the telephone numbers 36687825-36687830 are 36687826, 36687827, 36687828, 36687829 The gap between the telephone numbers 36687831-36687835 are 36687832, 36687833, 36687834 Using C programming language
I need help with this coding assignment.
The Springfork Amateur Golf Club has a tournament every weekend. The club president has asked you to write a program that will read each player's name and score as keyboard input, and then save these as records in a file named golf.txt . First, the program should ask the user for the number of players. Then, it should ask the user for each name and score individually. The file golf.txt should be structured so that there is a line with the player's name, followed by their score on the next line. Here is an example: Emily 30 Mike 20 Jonathan 23 Look carefully at the following sample run of the program. In particular, notice the wording of the messages and the placement of spaces and colons. Your program's output must match this. Sample Run (User input shown in bold) Enter number of players :4↵ Enter name of player number 1 : Jimmy↵ Enter score of player number 1 : 30↵ Enter name of player number 2 : Carly↵ Enter score…
