Why there is no output?

Question

i=0
while i <= 12:
print("@"*i)
i+=i

Can any one tell me why it isn't going any output
Not even 'No output'

Initialize <i> with 1 instead of 0. `i += i` while <i> was initialized by one will just add zero to zero. Besides print(" @" * 0) doesn't really print anything at all 😁
