Can anyone please help me with this program. Parts A and B are already done. NEED HELP WITH PART C (i, ii, iii, iv).

Write a Python program that draws a pie chart of the n most frequent letters in "Words.txt file. The program will: Use Tkinter to build an interface to input the number of letters,n, in the pie chart: Have a module imported that determines the probability of letters in "Words.txt file: a. Frequency of letter Frequencies of all letters Probability of letter c. Use Turtle to draw the pie chart: Area of each segment of the pie chart is proportional to the probability of the corresponding letter: Central angle of segment 2? Probability of letter iL Each segment has a different color; il Each segment has a legend showing the letter and its probability iv. The last segment represents "All Other Letters" and their cumulative probability. In the graph below, the probability of All Other Letters is one minus the sum of the probabilities of letters e,s, and ?,01102 v Note Beware! Using graph tools or packages to draw the pie chart will not be considered an acceptable solution
