How to print the values of parameters passed into a function-CodePudding

I don’t know how to retrieve, store and print the values of parameters passed into a function. I do know that many posts are related to this question, but I couldn't find anything that matches the simple thing I would like to do.

Let’s take a very simple example:

def times(value, power):
    return value**power

If I run this function and then write:

x = times(2.72, 3.1)
print(f'Result of calculation is: {x: .6f}')

then the output will be:

Result of calculation is:  22.241476

OK, but this is not what I would like to have; I would like to be able to print the result, the value and the power, and have the following lines as output, preferably using a print as above; something like print(f’some text here: {something}’)…

Desired output:

Result of calculation is:  22.241476
Value passed to function was:  2
Power passed to function was:  3

What is the most effective way to do that?

CodePudding user response：

You can always just add more "print" lines.

So the code would look something like this:

def times(value, power):
    print(f'Result of calculation is: {x: .6f}')
    print(f'Value passed to function was: {value}')
    print(f'Power passed to function was: {power}')

and then you can just pass the values into the function like so:

times(2.72, 3.1)

CodePudding user response：

You will need to first store the parameters in variables in the code that calls the function.

Assuming the function 'times' is defined.

a = 2.72
b = 3.1
x = times(a, b)
print(f'Result of calculation is: {x: .6f}')
print(f'Value passed to function was: {a}')
print(f'Power passed to function was: {b}')

Please try the following code. It uses the concept of closure (google it). Hope it is helpful.

def times():
    value = float(input('Enter a value:'))
    power = float(input('Enter a power: '))

    def raise_to_power():
        return value ** power
    print(
        f'Result of calculation is: {raise_to_power(): .6f}\nValue passed to function was: {value}\nPower passed to function was: {power}')


times()
