How to get firebase value?

Question

Python

Help me get the value of "Money" (to display 100). I looked through everything that is possible, but it did not work out to display this particular number.
The code I used:

user = ctx.author.id
  y = db.reference(f"/{user}/Balance")
  y.update({
    "Money": 100
  })
  h = y.get("Money.val")
  print(h)
