In this case, the key being sorted on is the function object x.name.lower,
not the result of the call.
It might make more sense if you break the lambda out into a separate def
statement, like this:
def myKeyFunc(x):
return x.name.lower # Return the function that produces the lower-cased
name.
print list(sorted(all_the_stuff, key=myKeyFunc))

In this case, you are calling x.name.lower, and the key being used is the
result of that call.
And heres what this one looks like broken down:
def myKeyFunc(x):
return x.name.lower() # Return the lower-cased name.
print list(sorted(all_the_stuff, key=myKeyFunc))
