Return more than one value from a function

[Brussely]

I want my function to return more than one value. Is it possible?

Code

>>> def f(x):
...    power = x ** 2
...    sqr = x ** (1.0 /2)
...    return sqr
...    return power
...
>>> f(2)
1.4142135623730951

But it is only returning the square root.

The function will exit at the first return it finds. So in your example the first return returns sqr and exits the function never reaching the second return.

You can return as many values as you want in a single return using a tuple. Just separate them with a comma:

Code

def f(x):
   power = x ** 2
   sqr = x ** (1.0 /2)
   return sqr, power
 
x = 2
sqr, power = f(x)
print "The square root of", x, "is", sqr
print "The power of", x, "is", power

Notice how the values are unpacked into both variables when the function returns.
