这段代码有什么问题？我在这段代码中遇到问题

Question

a = float(input("Enter first number: "))
b = float(input("Enter second number: "))
print('The product of {first} and {sec} is: ',a*b).format(first = a, sec = b)
print('The sum of {first} and {sec} is: ',a+b).format(first = a, sec = b)

AttributeError 的情况即将到来。你们能解决这个问题吗？学校项目需要它。

Answer 1

您的参数顺序错误：

a = float(input("Enter first number: "))
b = float(input("Enter second number: "))
print('The product of {first} and {sec} is: '.format(first=a, sec=b), a*b)
print('The sum of {first} and {sec} is: '.format(first=a, sec=b), a+b)

不过，用

f-strings

会更好：

a = float(input("Enter first number: "))
b = float(input("Enter second number: "))
print(f'The product of {a} and {b} is: {a*b}')
print(f'The sum of {a} and {b} is: {a+b}')

输出：

Enter first number: 12
Enter second number: 4
The product of 12.0 and 4.0 is: 48.0
The sum of 12.0 and 4.0 is: 16.0
