Printing return value in function, Python

Question

When I print the value that my function returns, it has strange characters.

If I print the value that I care inside the function, I obtain the right value: 0.653594771242

If I print the value that the function returns, I obtain: function alpha at 0x05870630

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. Functions in python are objects.

If you want to print the value returned by the function then this may help you.

print(alpha(0.817,0.713))

Answer 2

This way would probably make more sense to you.

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.

Answer 3

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