How to change Python variables based on JSON response?

I am trying to get a Python variable based on a JSON response.

When I request the JSON I want to save some of the information as

X = content[0]['OrderItemList'][0]['ItemID']

What I need is the variable X to change if it is a certain number.

For example, if x = 3, I need it be changed to x = 5. So far I have been able to change the variable with math and other string or integer changes. I think a loop would work but I am not sure. 

if request.method == 'POST':

    x = content[0]['OrderItemList'][0]['ItemID'] 

    pseudocode

    if x = 2 chnage to x = 5

Simply set x to the value from json, then use if/elif statements to reassign x.

x = content[0]['OrderItemList'][0]['ItemID']
if x in [2, 3]:
  # if x is 2 or 3, set to 5
  x = 5
elif x == 4:
  x = 2

or if you have a lot of conditions on which to change x, consider using a dict :

changetos = {2: 5,
             3: 5,
             #... 
            }
x = content[0]['OrderItemList'][0]['ItemID']
x = changetos.get(x, x) # if x not in changetos, leave x as is
