Show Equation of a Variable Instead of the Answer?

Is there a simple way to show the equation of a var instead of the answer?

Example: add = 2 + 2

print("ADDITION: " + ?? + " = " + str(add))

Replace ?? with whatever to print:

ADDITION: 2 + 2 = 4

So that I can change the variable and it would still be correct?

You can store the expression as a string for the "variable representation" you want, and eval it to get the "answer".

expr = '2 + 2'
print('ADDITION: %s = %s' % (expr, eval(expr))

However, "eval is evil", so use it with caution (e.g. don't eval an expression you get as an input from the user).

You can try creating two variables:

a = 2
b = 3

then compute the sum:

add = 2 + 3

and print:

print("ADDITION: " + str(a) + " + " + str(b) + " = " + str(add))

or print it using format()

print("ADDITION: {} + {} = {}".format(a, b, add))
