- Alert dont submit AI generated answer. Need some help Your task: Using Python Write a basic program that prompts the user for a filename. Then, create a file that generates ten random integers. The file that your program creates should be a .txt file and I should be able to run it on both a Mac and Windows operating system. Important: The numbers that are generated must be truly random (hint: built-in function)Python Question: Which statement correctly opens an existing file if you want to add lines to it? A. open('data.txt', 'a') B. f = open('data.txt', 'append') C. f = open('data.txt', 'a') D. data = open('data.txt', 'w')The 'a' mode appends new data to the end of an existing file. But if the file is nonexistent, it does not create a new one to append the data.True or False
- Python script that uses the os module 1. Display the current working directory. 2. Create a new directory called "test_dir" in the current working directory. 3. Change the current working directory to "test_dir". 4. Verify the current working directory has been changed. 5. Create a new file named "test_file.txt" in "test_dir". a. You must write the following contents to test_file.txt: This is a test file. 6. Verify that "test_file.txt" was created by listing the contents of "test_dir". 7. Display the file size and the last modification time of "test_file.txt". 8. Change the name of "test_file.txt" to "new_test_file.txt". 9. Verify the name change by listing the contents of "test_dir" again. 10. Finally, remove "new_test_file.txt" and "test_dir", verifying each deletion by listing the contents of the parent directory.// Ex 7-1.cpp in this exercise you will use what you learned about opening a file and reading input //Read and follow the comments submit your code through the Exercise one quiz #include <fstream> #include <iostream> #include <string> using namespace std; int main() { //this is the code for exercise 7-1 ofstream data_in; //find and fix the error in this line data_in.open(myDVDFile.dat); //find and fix the error in this line string dvdName, dvdPrice, dvdShelf; data_in >> dvdShelf; data_in >> dvdPrice; data_in >> dvdName; /* use notepad to create a datafile named myDVDFile.dat that contains the following data Fargo 8.00 1A Amadaus 2.00 2C Casino 7.50 3B */ //add print statements to output dvdShelf, dvdPrice, dvdName record the values in your workbooks // there is a problem with the values fix it } // End of main functionComputer Science Hello I have a Powershell question but my answer doesn't seem to work.

- Encode the file by adding 10 to every byte in the file. Write a gramthat prompts the user to enter an input file name and an output file name and savesthe encrypted version of the input file to the output file.When a program works with an input file, a special value known as a(n) __________ is internally maintained for that file and marks the location of the next item that will be read from the file. a. input locator b. accumulator c. read position d. sequential read valueSimple SHELL (.sh) script Write a SHELL script (minExF.sh) that takes a csv file ("Comma Separated Values", a text file that can be manipulated by Excel) as an argument containing the grades of the mid-term (called intra) exams with the passing thresholds and calculates the minimum grades that must be obtained in the Final exam by adding them as a column to the initial information in the output file. Note: To manipulate large integers and real numbers use the Unix command bc . Here is an example of how to use of this command to add two non-integer numbers stored in the variables VAR1 and VAR2 : VAR1=5.5VAR2=3.14159RESULT='echo $VAR1+$VAR2 | bc'echo $RESULT The result displayed on the screen will be 8.64159.
