Step by step
Solved in 3 steps
- Answer the given question with a proper explanation and step-by-step solution. 1- Write code that does the following: opens an output file with the filename number_list.txt, uses a loop to write the numbers 1 through 100 to the file, then closes the file.example code of how to generate a dictionary of all the words within a file using loops. No functions can be usedFill in the blank question- Only answer needed without explanation Q. _____________ utility is used to check the file system in super blocks.
- Make the following modifications for the solution above: name the output/input file "myRandomNumbers.txt" use a loop to output 17 random numbers to the file after creating the file, close it open the file for input and read the contents and then total the numbers in the file determine the average of the numbers in the file determine the highest and lowest numbers in the file DO NOT USE PYTHON BUILTIN FUNCTIONS TO CALCULATE THE AVERAGE OR THE HIGHEST AND LOWEST NUMBERS an expected number of modules/functions would be in the 5-8 range Display your results: the numbers generated on a single horizontal line the calculated total and average the highest and lowest number in the file Be sure to use clear prompts/labeling for input and output.Modify below program to read dictionary items from a file and write the inverted dictionary to another file.

- Create a new Python program (you choose the filename) that contains a main function and another function named change_list. Refer to the SAMPLE OUTPUT after reading the following requirements. In the main function: create an empty list. use a for loop to add 12 random integers, all ranging from 50 to 100, to the list. use second for loop to iterate over the list and display all elements on one line separated by a single space. display the 4th element, the element at index 9, and the smallest element. call the change_list function with your list as its sole argument. In the change_list function: use a slice to make a new list from the list that was passed into this function. The new list should hold the middle 6 elements of the list that was passed in. NOTE: you must accomplish this step with a slice. use a function to determine the size of the new list. Print the size. sort the new list in ascending order and return the sorted list to main.
