Problem 9. Consider the following program mystery.-py: import stdio x = stdio.readString () y = stdio.readString () stdio.write(x + 'L' + y) stdio.write ('') stdio.write (y + 'R' + x) stdio.writeln () Next, suppose that the file input.txt Contains the two strings F and F separated by a space. What does the following command output? $ python3 mystery.py < input.txt | python3 mystery.py | python3 mystery.py

python: Open the file mbox-short.txt and read it line by line. When you find a line that starts with 'From ' like the following line:From stephen.marquard@uct.ac.za Sat Jan 5 09:14:16 2008 You will parse the From line using split() and print out the second word in the line (i.e. the entire address of the person who sent the message). Then print out a count at the end. Hint: make sure not to include the lines that start with 'From:'. Also look at the last line of the sample output to see how to print the count. You can download the sample data at http://www.py4e.com/code3/mbox-short.txt my code: fname = input("Enter file name: ")if len(fname) < 1: fname = "mbox-short.txt" fh = open(fname)count = 0 print("There were", count, "lines in the file with From as the first word")

can you do it python

I have a bit of code that is intended to read a file ("students.txt") and calculate the average, highest, and lowest scores from given information. (students.txt reads: " Mark Thompson 72.50James Taylor 100.00Daniel Price 80.2Busy Phillips 63.0 " ) This is the code I have: I have tweaked it to output the highest and lowest but I cannot get it to read the file. I have saved the file into the directory of the program but nothing seems to be working. I am also stumped on the formatting of the calculations. //////////////////////////////////////////// #include <iostream>#include <fstream>#include <cmath>#include <string>#include <iomanip>using namespace std; int main() { ifstream inFile; // This is a declaration of the inFile that holds all the gradesstring fileName; // This is the filename that the user will enterconst int min = 63.0; // This is a constant min used to find the lowest scoreconst int max = 100.0; // This is the constant max used to find the...

Write a C program to read in a text file and provide a count ofa. The number of strings in the file, where a string begins with anon–white space character and ends with a white space character.b. The number of words in the file, where a word begins withan alphabetic character (e.g., a–z or A–Z) and ends with anonalphabetic character.c. The number of unique words in the file. Words are as defined inpart b. The set of unique words has no duplicates.d. The frequency of words in order of most frequent to least frequent.In other words, analyze the text file, count the number of times eachword occurs, and display these counts from most frequent word toleast frequent.

1. Write a Java program that reads the file "input.txt" and calculates and prints the average of all integer numbers in this file. SAMPLE OUTPUT: throws FileNotFoundException try/catch OUTPUT SAMPLE #1 for input.txt: 1 2 3 4 5 6 x x x 8 12 x x 34 x x 10 20 Please input the name of the file to be opened: input.tx --- File Not Found! OUTPUT SAMPLE #1 for input.txt: 1 2 OUTPUT SAMPLE #2 for input.txt: 1 2 3 4 5 6 x x x 8 12 x x 34 x x 10 20 Please input the name of the file to be opened: input.txt Number # 1 is: 1 Number # 2 is: 2 3 4 5 6 x x x 8 12 x x 34 x x 10 20 Number # 1 is: 1 Number # 2 is: 2 Number # 3 is: 3 Number # 4 is: 4 Number # 5 is: 5 Number # 6 is: 6 Number # 3 is: 3 Number # 4 is: 4 Number # 5 is: 5 Number # 7 is: 8 Number # 8 is: 12 Number # 9 is: 34 Number # 6 is: 6 Number # 10 is: 10 Number # 7 is: 8 Number # 11 is: 20 The average of 11 numbers/file = 9.55 Number # 8 is: 12 Number # 9 is: 34 Number # 10 is: 10 OUTPUT SAMPLE #2 for Number # 11 is: 20 The average of 11...

Write a program that will input the contents of a text file containing integers then writes each number and the frequency of that number appearing in the file. The output should look like the following sample output: Number Frequency 1 2 3 3 Also, copy the contents of the text file under your code Hints: Sort the list in ascending order before counting the numbers.

Write code that uses the input string stream inSS to read input data from string userInput, and updates variables userMonth, userDate, and userYear. Sample output if the input is "Jan 12 1992": Month: Jan Date: 12 Year: 1992

In Python.

Write a program called p2.py that has the following functionality:1. read input from a file containing a list of words (each word is written on its own line) andstore the data (strings) in a listHint: try using the readline() function or a for loop2. randomly select a string from the list3. output / write the selected string to a new file

Write code to read the content of the text file input.txt .●くろまる For each line in input.txt , write a new line in the new text file output.txtthat computes the answer to some operation on a list of numbers.●くろまる If the input.txt has the following:o Min: 1,2,3,5,6o Max: 1,2,3,5,6o Avg: 1,2,3,5,6●くろまる Your program should generate output.txt as follows:o The min of [1, 2, 3, 5, 6] is 1.o The max of [1, 2, 3, 5, 6] is 6.o The avg of [1, 2, 3, 5, 6] is 3.4.
