Python convert decimal to hex

I have a function here that converts decimal to hex but it prints it in reverse order. How would I fix it?

``````def ChangeHex(n):
if (n < 0):
print(0)
elif (n<=1):
print(n)
else:
x =(n%16)
if (x < 10):
print(x),
if (x == 10):
print("A"),
if (x == 11):
print("B"),
if (x == 12):
print("C"),
if (x == 13):
print("D"),
if (x == 14):
print("E"),
if (x == 15):
print ("F"),
ChangeHex( n / 16 )
``````

If you want to code this yourself instead of using the built-in function `hex()`, you can simply do the recursive call before you print the current digit:

``````def ChangeHex(n):
if (n < 0):
print(0)
elif (n<=1):
print n,
else:
ChangeHex( n / 16 )
x =(n%16)
if (x < 10):
print(x),
if (x == 10):
print("A"),
if (x == 11):
print("B"),
if (x == 12):
print("C"),
if (x == 13):
print("D"),
if (x == 14):
print("E"),
if (x == 15):
print ("F"),
``````
