1.Write an Employee class that keeps data attributes for the following pieces of information:

a. Employee name

b. Employee number Next, write a class named ProductionWorker that is a subclass of the Employee class. The ProductionWorker class should keep data attributes for the following information:

c. Shift number (an integer, such as1 for morning shift, 2 for evening shift)

d. Hourly pay rate Write the appropriate accessor and mutator methods for each class

Given a string, write a program to print a secret message that replaces characters with numbers 'a' with 1, 'b' with 2, ..., 'z' with 26 where characters are separated by '-'.

Note: You need to replace both uppercase and lowercase characters. You can ignore replacing all characters that are not letters.

Input

Explanation

For example, if the given input is "python", "p" should replaced with "16", similarly"y" with "25","t" with "20","h" with "8","o" with "15","n" with "14". So the output should be "16-25-20-8-15-14".

  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 

Print each string in the list and whether or not it has any duplicates based on the return value of has_duplicates for that string. For example, the output for "aaa" and "abc" would be the following. 

aaa has duplicates

abc has no duplicates

Print a line like one of the above for each of the strings in test_dups.

def histogram(s):

   return d 

  Implement has_duplicates by creating a histogram using the histogram function above. Instead, your implementation should use the counts in the histogram to decide if there are any duplicates. 

Write a loop over the strings in the provided test_dups list.
