Exercise 84 *

Write a Python program as function that takes as parameter a string s and which returns the list of all repeated character in the string s. Example: if s = "python language", the fuction returns the list :
['n', 'a', 'g']

Solution

# create a function to test if given character is repeated within a given string
def isRepeated(s,c):
    counter = 0
    for x in s:
        if x == c:
            counter = counter + 1
    if counter >= 2:
        return True
    else:
        return False
# function which determines the list of all repeated characters
def listRepeated(s):
    repeated = []
    for x in s:
        if isRepeated(s,x) and x not in repeated:
            repeated.append(x)
        
    return repeated
          
# Example
s = "python language"
print("The list of repeated character is : " , listRepeated(s))
# The output is: 
# The list of repeated character is :  ['n', 'a', 'g']
