please code in python count_word: This function takes a filename and a keyword. Return the number of times the keywordoccurs in the file. Initialize a variable to keep track of the number of times the keyword appears.Traverse the file by line. Use the count method on each line to find the number of times the keywordappears in it and add that amount to the variable
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.
