How to get a variable from one Notebook into another

[CrhIT]

I'm running a notebook, which output needs to be stored and used in a new notebook. How can this be done?

Let's say in Notebook_1 the code is

import pandas as pd

# Create an example pandas DataFrame
data = {
    "ID": [1, 2, 3, 4, 5],
    "Name": ["Alice", "Bob", "Charlie", "David", "Eve"],
    "Age": [25, 30, 35, 40, 45],
    "Salary": [50000, 60000, 70000, 80000, 90000],
    "Department": ["HR", "IT", "Finance", "Marketing", "Sales"]
}

df = pd.DataFrame(data)

I want to reference df in a new notebook so I have no need to rewrite the whole code in the new notebook.
