n2上的语法无效

Question

我已尝试使用此代码尝试了解为什么它会继续使用无效语法：

def ex27() :

    print("program will add 4 numbers and respond with an answer")
    n1 = int(input("Enter N1: ")
    n2 = int(input("Enter N2: ")
    n3 = int(input("Enter N3: ")
    n4 = int(input("Enter N4: ")
    n5 = n1 + n2 + n3 + n4
    print(n1, "+", n2, "+", n3, "+", n4, "=", n5)

n2 = int(input("Enter N2: ") - 这就是它出现的那一行，它说n2是一个语法错误。

Answer 1

您没有关闭括号。

每一行应如下所示：

n1 = int(input("Enter N1: "))

在行尾有两个括号！

Answer 2

检查一下：

def ex27() :

    print("program will add 4 numbers and respond with an answer")
    n1 = int(input("Enter N1: "))
    n2 = int(input("Enter N2: "))
    n3 = int(input("Enter N3: "))
    n4 = int(input("Enter N4: "))
    n5 = n1 + n2 + n3 + n4
    print(n1, "+", n2, "+", n3, "+", n4, "=", n5)

你错过了正确的右括号。
