Why i can't do calculations in loops

Question

print("kwota wprowadzana")
x=float(input())
print (" procent skladany")
y=float(input())
print ("na ile dni")
z=int(input())

while i<z:
x=x+x*(y/100)
i=i+1
if i==z:break
print(x)

Compiler shows at x and saying expected na intended block but i dont know why.Can anybody explain this to me?

Answer 1

OMG that was that easy. Thanks a lot.

Answer 2

I love how modern computer languages tell you what’s wrong with the code and what line it’s in…makes life much easier😅

Answer 3

Ok i understand that "if" here Has no point but how i can intend lines in loop ? Using {} or what ?
