在函数中打印返回值，Python

Question

When I print the value that my function returns, it has strange characters. 当我打印函数返回的值时，它具有奇怪的字符。

If I print the value that I care inside the function, I obtain the right value: 0.653594771242 如果在函数中打印我关心的值，则将获得正确的值：0.653594771242

If I print the value that the function returns, I obtain: function alpha at 0x05870630 如果我打印函数返回的值，则会获得：0x05870630处的函数alpha

def alpha(v1,v2):

    a=(v1,v2)
    b=1/sum(a)
    print(b)
    return b

alpha(0.817,0.713)

print(alpha)

Answer 1

This is because you are printing an object ie a function. 这是因为要打印对象即功能。 Functions in python are objects. python中的函数是对象。

If you want to print the value returned by the function then this may help you. 如果要打印函数返回的值，则可能会有所帮助。

print(alpha(0.817,0.713))

Answer 2

This way would probably make more sense to you. 这样对您可能更有意义。

def alpha(v1,v2):

    a=(v1,v2)
    b=1/sum(a)
    print(b)
    return b

result = alpha(0.817,0.713)

print(result)

This way the function is returning the value to result then you are simply printing the result. 这样，函数将返回结果值，然后您只需打印结果即可。

Answer 3

代替print（alpha），您需要编写print（alpha（0.817,0.713））
