1994 Weekly Gas GraphIn the student sample programs for this book, you will find a text file named 1994_Weekly_Gas_Averages.txt. The file contains the average gas price for each week in the year 1994.(There are 52 lines in the file.) Using matplotlib, write a Python program that reads thecontents of the file then plots the data as either a line graph or a bar chart. Be sure to displaymeaningful labels along the X and Y axes, as well as the tick marks. (in python)

Assignment 5C: Level Map Creator. There are a variety of ways that game developers store their level layouts. One simple method is to associate level elements with certain symbols, and then storing them in a 2D grid inside a text file. We will use our knowledge of 2D arrays to create a very simple Level Map Creator tool. The program should prompt the user to enter a width and height for the level. Then it should initialize a 2D array and fill every element with the "*" symbol. Afterwards, the user should be given the following options via a menu: 1. Clear Level Re-initialize the 2D array and fill every element with the "*" symbol. 2. Add Platform Prompt the user to enter a starting point and length for the horizontal platform. Replace those elements in the 2D array with the "=" symbol. If the length is longer than the number of columns (or out of bounds), notify the user that this is not possible. 3. Add Item Prompt the user to enter a column and row index. Replace that element in the…

Problem2 Write a program that display the position of a given element in an array. You should print the index (i.e. the position) of the element. If the element appears more than one time than you should print all its positions. The size of the array should be entered by the user. If the element does not occur then you should display element not found. Sample1: Enter the size of the array: 5 Enter an array of size 5: 44 5 13 44 67 Enter the element to find: 44 44 is found at position 44 is found at position 44 occurs 2 time(s) Sample2: Enter the size of the array: 4 Enter an array of size 4: 12 150 17 20 Enter the element: 18 18 is not found
