- Use python language for a program that modifies and sorts the content of a specific csv file based on the inputted column name. The program should ask Enter filename: Enter column name to be sorted: Additionally, the csv file must be modified and no additional csv files must be created. The application will catch and display an error message "the file does not exist" if the csv file does not exist. *if possibe, do not use pandas*In Python Write a program that consists of (at least) two function: A function that creates and saves data in a file. The saved data represents exam grades. In the function, you will create n random numbers in the range [0,100], where n is the number of students. The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile. The main should perform validation for n (should be > 0), and the filename (should end with .txt). I will explain how to validate strings in the coming lecture. Hint: a good developer will write four functions to solve the problem.1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the file into the array. 6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array. Return the maximum value from the function (the function will be of type int). 7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages. Ensure the output is readable.
- Code should be in Python. A photographer is organizing a photo collection about the national parks in the US and would like to annotate the information about each of the photos into a separate set of files. Write a program that reads the name of a text file containing a list of photo file names. The program then reads the photo file names from the text file, replaces the "_photo.jpg" portion of the file names with "_info.txt", and outputs the modified file names. Assume the unchanged portion of the photo file names contains only letters and numbers, and the text file stores one photo file name per line. If the text file is empty, the program produces no output. (Examples in image)AaBbCcDd AaBbCc I U abe x, I Normal TNo Spac Font Paragraph ... 2 3 5 6 Write a program that asks the user for the names of two files. The first file should be opened for reading and the second file should be opened for writing. the program should read the contents of the first file, change all characters to lowercase, and store the results in the second file. The second file will be a copy of the first file, except that all the characters will be lowercase. Use Notepad or another text editor to create a simple file that can be used to test the program Required Submission: 1. Java Program 2. Text file created using Notepad 3. Exception Handling (Especially when reading File not found, End of the file, etc) 2. Sample Output (taken using Screenshot) on a Word documentUnfortunately, the change from int to Month means that it's harder to read Date objects from an input file, since it doesn't work if a user enters Date::jan. Write a toMonth function that can be used to enter a month as an integer. Throw invalid_argument if it fails. Month m = toMonth (3); // returns Month::mar udts.cpp 1 #include 2 #include 3 #include "date.h" using namespace std; 4 6. /** Construct a valid Month. 7 8. @param mm the month in the range 1-12 9. @exception throw invalid_argument if out of range. @return the correct Month. 10 11 */ Month toMonth(int mm) { 12 13 14 15 16 17 } Demo.cpp 1 #include 2 #include 3 #include "date.h" 4 using namespace std; 5 6 int main() 7 { cout « "Enter date as mm/dd/yyyy: "; int mm, dd, yyyy; char slash; cin >> mm >> slash » dd >> slash » yyyy; 8 10 11 12 13 try { Date d = makeDate (toMonth(mm), dd, yyyy); cout <« "The date is " << d << endl; } catch (invalid_argument& e) { cout « e.what() « endl; } 14 15 16 17 18 19 20 21 22 }

A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies. Below is an example file along with the program input and output: example.txt I AM SAM I AM SAM SAM I AM Enter the input file name: example.txt AM 3 I 3 SAM 3 The program should handle input files of varying length (lines).

- wordSort.py: Write a program that reads words from a file (filename given as a command-line argument) and prints them in (case insensitive) sorted order. For example, if the input file contains:If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print (one word per line, compressed here for brevity):a baby Check DJ hook I'll Ice ice If it it my outproblem revolves solve the there's while yowordCountDistinct.py: Write a program that reads words from a file (filename given as a command-line argument) and prints the number of distinct words. Words that differ only in case should be considered to be equivalent.For example, using the input: If there's a problem yo I'll solve itCheck out the hook while my DJ revolves itIce ice baby The program should print 18.The function file_first_chars in python takes one parameter, fname, the name of a text file, and returns a string made up of the first character from each line in the file. You may assume there are no blank lines in the file. Hint: Use a for loop to iterate over the lines of the file and accumulate the string of first characters. NOTE: Return the function, don't print For example: Test Result print(file_first_chars("wordlist1.txt")) hsaem
