How to get json part inside request?

Question

Python

Hello!
Let's say I have this json:
-object {5}
-data [20]
-product [14]
- 1{17}
- 2{17}
-3{17}
-var1 :10
-var2: 20
-request {11 }
- var3:
11.01.11 - var4: 12.01.11
status: 200

If for product it works like this:
for i in dataJson['product']:
print(i['var1'], i['var2'])
And returns ok all unique values ​​you want.

Then
for i in dataJson['request']:
print(i['var3'], i['var4'])
doesn't work.
Returns simply:
var3
var3
var3.
Tell me, please, what is the problem? How to correctly pull out data in request?
