Please explain to me, why in the following code, in the first line of output, there is a sign ">" standing before "spam"?

Question

class SpecialString:
def __init__(self, cont):
self.cont = cont
def __gt__(self, other):
for index in range(len(other.cont)+1):
result = other.cont[:index] + ">" + self.cont
result += ">" + other.cont[index:]
print(result)
spam = SpecialString("spam")
eggs = SpecialString("eggs")
spam > eggs
Output:
>>>
>spam>eggs
e>spam>ggs
eg>spam>gs
egg>spam>s
eggs>spam>
>>>

Answer 1

Because the first iteration other.cont[:index] returns an empty string (given that index=0).

Answer 2

Now I got it. It is obvious. Sometimes something goes wrong in our brains :).
