python 3.x - How do I start using a .json file to read and write variables externally?

Question

In this situation, I want these 4 variables to be saved in an external .json file. If they are not present in the .json file, then I want these questions to be asked. They are global variables.

monthlyWage = int(input("What is your monthly wage? "))
monthlySpendings = int(input("What are your monthly spendings? ")) 
monthlyOverdraft = int(input("What is your monthly overdraft? "))
monthlySavings = int(input("How much do you add into your savings account per month? "))
totalSpendings = int(monthlySpendings + monthlyOverdraft + monthlySavings)
