Lambda Expressions: Returning Multiple Values

I want to implement the function via a lambda expression as follows:

Instead of this:

def f(x, y, z):
     return x + 1, y * 2, z * 3

I want to use a lambda expression, like this:

f = lambda x, y, z: x + 1, y * 2, z * 3

The stacktrace:

*Traceback (most recent call last):
  File "<input>", line 1, in <module>
NameError: name 'y' is not defined*

Why is this causing an error? How can this be done?

Your tuple is not binding correctly - the lambda is ending at the first comma. Put parens around the tuple:

f=lambda x,y,z: (x+1,y*2,z*3)
