python could not convert string to float
#You have to simply convert a string to float.
num1 = float(input("Enter a number: "))
num2 = float(input("Enter another number: "))
result = num1 + num2
print(result)
#In this case if user puts a number such as 10 + 10 it will be 20: 10 + 10 = 20
#if you don't convert it then it will add up the string like below
num1 = input("Enter a number: ")
num2 = input("Enter another number: ")
result = num1 + num2
print(result)
#The out put will be like so: "10" + "10" = 1010
