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.

15. World Series Champions If you have downloaded this book’s source code (the companion Web site is available at www.pearsonhighered.com/gaddis), you will find a file named WorldSeriesWinners.txt. This file contains a chronological list of the winning teams in the World Series from 1903 through 2009. (The first line in the file is the name of the team that won in 1903, and the last line is the name of the team that won in 2009. Note that the World Series was not played in 1904 or 1994, so those years are skipped in the file.) Write a program that lets the user enter the name of a team, and then displays the number of times that team has won the World Series in the time period from 1903 through 2009.
Tip: Read the contents of the WorldSeriesWinners.txt file into an ArrayList. When the user enters the name of a team, the program should step through the ArrayList, counting the number of times the selected team appears

- Write a program that animates the linear search algorithm. Create a list that consists of 20 distinct numbers from 1 to 20 in a random order. The elements are displayed in a histogram, as shown in Figure 10.17. You need to enter a search key in the text field. Clicking the Step button causes the program to perform one comparison in the algorithm and repaints the histogram with a bar indicating the search position. When the algorithm is finished, display a dialog box to inform the user. Clicking the Reset button creates a new random list for a new start.arrow_forwardMorse Code Python Part 1: Variable setup and prompt for input• To create the Morse representations, use periods “.” for dots and hyphens “-“ for dashes. Forexample, the Morse representation for the letter “C” is “-.-.”. A table of the alphabet can befound here.• Create a dictionary where the keys are a single letter (you can choose if it’s upper case or lowercase) and the value is a string with the Morse representation of the letter.• Create a loop to prompt the user for input – if they press the enter key, quit the loop.Otherwise, continue to prompt the user for input. Part 2: Convert to visual Morse code• Create an empty string to eventually hold the user’s output in Morse code. • Analyze each character of the user’s input. Since Morse code is capitalization independent thealgorithm should work the same for uppercase letters and lowercase letter.
