new to coding, when enter an equation of 1 * 5, I get "You are ...lazy". But I need to get "You are ...very lazy". Can you help me finding the problem?

Expected:

You are ... lazy ... very lazy

5.0

Do you want to store the result? (y / n):

Found:

You are ... lazy

5.0

Do you want to store the result? (y / n):

    msg_4 = "Do you want to store the result? (y / n):"
    msg_5 = "Do you want to continue calculations? (y / n):"

CodePudding user response：

You call float(x) and float(y), but this is not saved anywhere, so v1 and v2 will be '1' and '5', instead of 1 and 5.

If you set

x = float(x)
y = float(y)

, it should work.
