- step 1: Write a python program that will ask the user for their grocery list, one item at a time, and will write it to a file called groceries.txt. The program should create a new file called groceries.txt that will contain all of the user’s groceries when opened. Step 2: Modify the python program that creates a groceries.txt file so that if the user’s favourite fruit is not on the list, the program will append it to the end of groceries.txt file.arrow_forward1. 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.arrow_forwardΡYTHON Write a program that first reads in the name of an input file, followed by two strings representing the lower and upper bounds of a search range. The file should be read using the file.readlines() method. The input file contains a list of alphabetical, ten- letter strings, each on a separate line. Your program should output all strings from the list that are within that range (inclusive of the bounds). Ex: If the input is: input1.txt ammoniated millennium and the contents of input1.txt are: aspiration classified federation graduation millennium philosophy quadratics transcript wilderness zoologists the output is: aspiration classified federation graduation millenniumarrow_forward
