how to assign variables?

[saravanatn]

I think below code is what you looking for

num1=float(input("Please enter A number"))
num2=float(input("Please enter another number"))
num3=float(input("Please enter another number"))
if ((num1+num2)*num3 >100):
    print('calculation value ',(num1+num2)*num3)
else:
    print('number 1 ',num1)
