Solution Exercise 85: algorithm python to find the set of all charcters that make up a given string

Exercise 85

Write a python algorithm which determines the set of all characters that make up a string s. Example if s = "Python programming", the algorithm returns the set:

{'p', 'i', '', 'r', 'o', 'm', 't', 'a', 'h', 'y', 'P', 'g' , 'n'}

Solution

# create a function which returns all the characters that make up a string s
def characterSet (s):
    # initialization of the set of characters
    Set = set ({})

    # iterate over all characters of the string s
    for x in s:
        Set.add (x)
    return Set

# Example
s = "Python programming"
print (characterSet (s))
# output: {'p', 'i', '', 'r', 'o', 'm', 't', 'a', 'h', 'y', 'P', 'g' , 'n'}
