Solution Exercise 69: Python algorithm to test if a given string is duplicated or not

Exercise 69

Write a Python program as a function which takes a string s as parameter and which returns True if the string is duplicated and False if not. Example if s = "HelloHello", the function must returns True.

Solution

def duplicatedString(s):
    n = len(s)
    if n%2 ==0:
        m = int(n/2)
        if s[0:m] == s[m:]:
            return True
        else:
            return False
    else:
        return False
    
# Examples
s1 = "HelloHello"
s2 = "Python"
print(duplicatedString(s1)) # display True
print(duplicatedString(s2)) # display False
