because n2 syntax is not working

Question

n = (float (input ("primeira nota:"))
 n2 = (float (input ("segunda nota:"))
  n3 = (float (input ("terceira nota:"))
   n4 = (float (input ("quarta nota:"))
M = n + n2 + n3 * 3 + n4
M2 = M / 7 print ("Media do aluno", M2)

Answer 1

n = float (input ("primeira_nota:"))
n2 = float (input ("segunda_nota:"))
n3 = float (input ("terceira_nota:"))
n4 = float (input ("quarta_nota:"))
M = n + n2 + n3 * 3 + n4
M2 = M / 7
print ("Media do aluno", M2)

Answer 2

A language has strict syntax. You have to follow the rules.

Here are some violations in your code:

1. You have to match the opening parentheses with closing parentheses
2. You have to match indentation level
3. You have to put new instructions into new lines.

Your code fixed would look like this:

n = (float (input ("primeira nota:")))
n2 = (float (input ("segunda nota:")))
n3 = (float (input ("terceira nota:")))
n4 = (float (input ("quarta nota:")))
M = n + n2 + n3 * 3 + n4
M2 = M / 7
print ("Media do aluno", M2)
