Why does it show 'break outside loop' in the code

Question

def DP(x,y,z):
q = x/y
w = q*z
print(y,',',x)
print(z,',',w)

def IP(x,y,z):
q = x*y
w = q/z
print(x,',',y)
print(z,',',w)

f = input('Enter the type of proportion in small case:')
if f == 'direct' or f == 'direct proportion':
e = input('Do you want to stop:')
while e == ' No' or e == 'no' or e == 'NO':
d = input('Do you want to stop:')
if d == 'yes':
break
else:
a = int(input('Enter the first number: '))
b = int(input('Enter the second number: '))
c = int(input('Enter the third number: '))
DP(a,b,c)
elif f == 'inverse' or f == 'inverse proportion':
e = input('Do you want to stop:')
while e == ' No' or e == 'no' or e == 'NO':
d = input('Do you want to stop:')
if d == 'yes':
break
else:
a = int(input('Enter the first number: '))
b = int(input('Enter the second number: '))
c = int(input('Enter the third number: '))
DP(a,b,c)
