I need help with an assignment. I need to begin with the Python code below:.   

alphabet = “abcdefghijklmnopqrstuvwxyz”   

test_dups = [“zzz”,”dog”,”bookkeeper”,”subdermatoglyphic”,”subdermatoglyphics”] 

test_miss = [“zzz”,”subdermatoglyphic”,”the quick brown fox jumps over the lazy dog”] 

def histogram(s):

   d = dict()

   for c in s:

     if c not in d:

        d[c] = 1

     else:

        d[c] += 1

   return d 

I need to make a function called has_duplicates that takes a string parameter and returns True if the string has any repeated characters. Otherwise, it should return False.  

Then I need to implement has_duplicates by creating a histogram using the histogram function above.My implementation should use the counts in the histogram to decide if there are any duplicates. 

I need to make a loop over the strings in the provided test_dups list. Then I need to print each string in the list and whether or not it has any duplicates based on the return value of has_duplicatesfor that string. For example, the output for “aaa” and “abc” would be the following. 

aaa has duplicates

abc has no duplicates 

At last, I need to print a line like one of the above for each of the strings in test_dups. 

Part 2 

I need to make a function called missing_letters that takes a string parameter and returns a new string with all the letters of the alphabet that are not in the argument string. The letters in the returned string should be in alphabetical order. 

My implementation should use a histogram from the histogram function. It should also use the global variable alphabet. It should use this global variable directly, not through an argument or a local copy. It should loop over the letters in alphabet to determine which are missing from the input parameter. 

The function missing_letters should combine the list of missing letters into a string and return that string. 

I need to make a loop over the strings in list test_miss and call missing_letters with each string. Then I must print a line for each string listing the missing letters. For example, for the string “aaa”, the output should be the following. 

aaa is missing letters bcdefghijklmnopqrstuvwxyz 

If the string has all the letters in alphabet, the output should say it uses all the letters. For example, the output for the string alphabet itself would be the following. 

abcdefghijklmnopqrstuvwxyz uses all the letters 

I need to print a line like one of the above for each of the strings in test_miss. 

Can you please include the following. 

• The provided code for alphabet, test_dups, test_miss, and histogram. 
• Your implementation of the has_duplicates function. 
• A loop that outputs duplicate information for each string in test_dups. 
• Your implementation of the missing_letters function. 
• A loop that outputs missing letters for each string in test_miss. 

I will also need the output from running my program.

Please help me plot this data in excel. I need to calculate the percent error…I need help as soon as possible. Everytime I try to right click in Excel the data will not work. Thank you!

1.    Open Excel
2. Start a new workbook in EXCEL.
3.           Enter the following experimental data:
4.                   For row A1 enter “x”.
5.                   In row A2 enter “0.110”.
6.                In row A3 enter “0.125”.
7.                 In row A4 enter “0.150”.
8.                In row A5 enter “0.210”.
9.                   In row B1 enter “y”.
10.                   In row B2 enter “1.08”.
11.                In row B3 enter “1.32”.
12.                 In row B4 enter “1.58”.
13.                In row B5 enter “2.04”.
14.            Finish entering data.
15. The next part is to graph the data and then complete a curve fit which we will skip. The curve fit will give the equation y = 9.23x + 0.13. Use this equation to calculate the predicted y or yfit.
16.            In row C1 enter “y fit”.
17.            In row C2 enter “= 9.23*A2 + 0.13”.
18.            Click to select row C2. Then left click twice on the lower right corner of C2. This will calculate for row C3 – C5.
19. Now calculate the square of the error
20.       In row D1 enter “Error squared”
21.            In row D2 enter “= (B2 – C2)^2”.
22.            Click to select row D2. Left click the lower right corner twice to repeat the calculation for rows D3 – D5.
23. Now calculate the root mean square error.
24.           In row D6 enter ” = sqrt( Average(D2:D5) )”.
25.           When this is done you should have a value of 0.0516 in row D6. This is the rms error.
26. To calculate the percent error of the fit, calculate the average of the |y|.
27.           In row E1 enter “Abs(y)”
28.           In row E2 enter ” = abs(B2)”.
29.           Click to select row E2. Left click twice on the lower right corner of E2 to calculate for row E3 – E5.
30.         In row E6 enter ” = Average(E2:E5)”.
31. You should have a value of 1.505 in row E6.
32. Now calculate the percent error
33.      In row F1 enter “Percent error —>”
34.          In row G1 enter ” = D6/E6*100″.
35. Now repeat with a new set of data and answer the question below.
36. Question: Enter the experimental data below into an EXCEL workbook.
37.        Height difference    Acceleration
38.                0.110           1.05
39.                   0.125           1.34
40.                 0.150           1.54
41.                   0.210           2.10
42. The equation of the best-fit line is y = 9.97x + 0.02. What is the percent error of the fit? Use 3 decimal places.

I need the answer for the percent error =_______
