In the code below I try to divide the values, but I end up getting a completely wrong answer from the calculation:
nota1 = input ("Digite a nota 1: ")
nota12 = input ("Digite a nota 1: ")
nota2 = input ("Digite a nota 2: ")
nota22 = input ("Digite a nota 2: ")
media1 = (float(nota1 + nota12)/2)
media2 = (float(nota2 + nota22)/2)
print(media1)
print(media2)
The result I get is this:
How do I get the calculation to go out correctly (5 + 10/2 = 7.5 and 7 + 7/2 = 7)?
You need to convert the data acquisition already. What your code is doing is adding two strings and then converting to float . The problem is that adding string is a concatenation, so when you type 5 and 10, you are getting 510.
You can simply do this:
nota1 = float(input("Digite a nota 1: "))
nota12 = float(input("Digite a nota 1: "))
nota2 = float(input("Digite a nota 2: "))
nota22 = float(input("Digite a nota 2: "))
media1 = ((nota1 + nota12) / 2)
media2 = ((nota2 + nota22) / 2)
print(media1)
print(media2)

But note that this code is not treating typos. The most correct is to catch the exception that can generate or check if what was typed is ok.
