Solution Exercise 83: python program to find the first repeated character within a given string

Exercise 83 *

Write a Python program as function that takes as parameter a string s and which returns the first repeated character in the string s. Example: if s = "django framework", the fuction returns the character 'a'

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 first repeated character
def firstRepeated(s):
    repeated = ''
    for x in s:
        if isRepeated(s,x):
            repeated = x
            break
    return repeated
          
# Example
s = "django framework"
print("The first repeated character is : " , firstRepeated(s))
# The output is: 'The first repeated character is :  a'
