Variable phrasing

Question

How would I get this to work so that the user could input b and data would swap to 40 in the equation and complete?

Sorry if this is a dumb or simple question! Thanks in advance.

a = 20
b = 40

data = input()

print(20 * 10 + data)

Answer 1

You could simply reassign data to b: b = int(data)
Or replace data with b in the print
