my code doesn't actually print anything out. i tried to call on the functions but they didn't work.

```
def denaryToBinary(denaryNo):#the name of the function
if denaryNo <= 255:#to make sure you can turn it into an bite
x = []#the empty binary list
y = 128#for the first 1 or 0 in binary
while y >= 1:#the while...else loop to turn my number into binary
if denaryNo - y > 0:#to make the number 1
denaryNo -= y#to take away the 2^y number
x.append(1)#to put a 1 there
y = y / 2#to get to the next number
elif denaryNo - y == 0:
x.append(1)#in case the binary number is equal to the 2^y number
else:
x.append(0)#to put a 0 there
else:
return x#when the loop finishes
def binaryToDenary(binaryNo):
binaryNo = [int(x) for x in str(binaryNo)]
x = len(binaryNo)
y = 0
if x >= 8:
return "this isn't a bite"
elif x <= 7:
while x > 0:
if binaryNo[x-1] == 1:
y += 2**(x+2)
x -= 1
elif binaryNo[x-1] == 0:
x -= 1
else:
return "wait...this isn't a binary number!"
else:
return y
carryOn = True
while carryOn == True:
binaryOrDenary = input("is the number you are going to input a binary or a denary number? B or D")
theInput = int(input("the number please!"))
if binaryOrDenary.lower() == "b":
print(binaryToDenary(theInput))
elif binaryOrDenary.lower() == "d":
print(denaryToBinary(theInput))
else:
print("that wasn't an option")
carryOn = input("do you want to carry on? y/n")
if carryOn.lower() == "y":
carryOn = True
elif carryOn.lower() == "n":
carryOn = False
else:
print("goodbye")
```
