Python all dictionaries in dictionary script

Hey freelancers!
First of all I got multiple nested dictionaries {}.
I want to run through all those automatically and get all keys and values.
In each nested dictionary, there can be X dictionaries and lists.
I want the subnames to be included in the future names, which means:

predictions: {
winner: {
id: 138
name: "Guarani Campinas"
comment: "Win or draw"
}
win_or_draw: true
under_over: "-3.5"
goals: {
home: "-1.5"
away: "-2.5"
}
advice: "Combo Double chance : draw or Guarani Campinas and -3.5 goals"
percent: {
home: "10%"
draw: "45%"
away: "45%"
}
}

predictions -> winners variable name will be = predictions_winners
predictions -> winners -> id variable name will be = predictions_winners_id
predictions -> goals -> home variable name will be = predictions_goals_home

etc.


The dictionaries can be very long.
