Судя по всему, примерно такая логика в основе:
def tmp(credit, percent, years):
for _ in range(years):
credit = credit + credit*percent/100
return creditПри вызове
tmp(1000, 10, 2)Ответ будет 1210.0
def tmp(credit, percent, years):
for _ in range(years):
credit = credit + credit*percent/100
return credittmp(1000, 10, 2)
