Answer 1

Dima, I could not use your advise. Бился целый день. А все оказалось проще. Теперь надо с "k" поработать, чтобы также, как "d" была переменной. Спасибо! Thanks!

Answer 2

Everything that requires repetitive action is better to do in a cycle:
while, for.
Like so:
int i=0
while i<d:
t=k*z[:len(z)-d]. +k*z[len(z)-d:len(z)]
print(t)
i+=1
