Check rotation Python

PROGRAM TO CHECK IF STRINGS ARE ROTATIONS OF EACH OTHER OR NOT

# Function checks if passed strings (str1 and str2)

# are rotations of each other

def areRotations(string1, string2):

    size1 = len(string1)

    size2 = len(string2)

    temp = ''

  

    # Check if sizes of two strings are same

    if size1 != size2:

        return 0

  

    # Create a temp string with value str1.str1

    temp = string1 + string1

  

    # Now check if str2 is a substring of temp

    # string.count returns the number of occurrences of

    # the second string in temp

    if (temp.count(string2)> 0):

        return 1

    else:

        return 0

  

# Driver program to test the above function

string1 = "AACD"

string2 = "ACDA"

  

if areRotations(string1, string2):

    print "Strings are rotations of each other"

else:

    print "Strings are not rotations of each other"




OUTPUT

Strings are rotations of each other
