I have 3 subsequent SageMath code cells C1, C2, C3 in a Jupyter notebook.

C1 sets a value a=1
C2 has an interact widget (say a slider for a1) using the value of a as default
C3 should assign the current value of a1 to a and proceed.

What do I have to write in C3 to access the current value of a1 in C2?

You can try with global variables, something like:

Cell 1

a = 3

Cell 2

@interact(n=a)
def square(n):
    global a1
    print("{} squared is {}".format(n, n*n))
    a1 = n

Cell 3

a1
