Write me a code to check if the given string is K and the other steps required given the following:
Check if the given string is K | Function that returns true if sub - string of length k starting at index i is also a prefix of the string.
k length sub - string cannot start at index i.
Character mismatch between the prefix and the sub - string starting at index i.
Function that returns true if str is K - periodic.
Check whether all the sub - strings str [ 0 , k - 1 ] , str [ k , 2 k - 1 ] ... are equal to the k length prefix of the string.

#Here is code to check if the given string is K and the other steps required.
 def isPrefix ( string , length , i , k ) :
	if i + k > length :
		return False
	for j in range ( 0 , k ) :
		if string [ i ] != string [ j ] :
			return False
		i += 1
	return True
def isKPeriodic ( string , length , k ) :
	for i in range ( k , length , k ) :
		if isPrefix ( string , length , i , k ) == False :
			return False
	return True
if __name__ == " _ _ main _ _ " :
	string = " geeksgeeks "
	length = len ( string )
	k = 5
	if isKPeriodic ( string , length , k ) == True :
		print ( " Yes " )
	else :
		print ( " No " )
