Python 每当编译和运行此代码时，控制台上打印的唯一内容是；这里有一些很酷的功能&引用；而我'；我不知道为什么

如标题所述，仅打印第一行。我相信这是一个简单的解决办法，但我只是错过了一些东西

我几乎什么都试过了

print("Here are some cool functions!")

def addition_function(a,b):
    return "The answer to %d plus %d is %d"%(a, b, a + b)

def subtraction_function(a,b):
    return "The answer to %d minus %d is %d"%(a, b, a - b)

def division_function(a,b):
    return "The answer to %d divided by %d is %d"%(a, b, a / b)

def multiplication_function(a,b):
    return "The answer to %d times %d is %d"%(a, b, a * b)

addition_function(5,5)

subtraction_function(10,5)

division_function(5,5)

multiplication_function(5,5)

因为这就是你打印的全部！您将只在控制台中看到它周围显式地有

print（）

print("Here are some cool functions!")

def addition_function(a,b):
    return "The answer to %d plus %d is %d"%(a, b, a + b)

def subtraction_function(a,b):
    return "The answer to %d minus %d is %d"%(a, b, a - b)

def division_function(a,b):
    return "The answer to %d divided by %d is %d"%(a, b, a / b)

def multiplication_function(a,b):
    return "The answer to %d times %d is %d"%(a, b, a * b)

print(addition_function(5,5))

print(subtraction_function(10,5))

print(division_function(5,5))

print(multiplication_function(5,5))

试试那个代码

您返回字符串，但从不打印它们。执行

打印（添加功能（5,5））

等操作。
