cute use of lambda

[Simon Forman]

class FakeQueue(list):
put = list.append
get = lambda self: self.pop(0)

[Paul Rubin]

class FakeQueue(list):
put = list.append
get = lambda self: self.pop(0)

from collections import deque
class FakeQueue(deque):
put = deque.append
get = deque.popleft

 

[Terry Reedy]

| class FakeQueue(list):
| put = list.append
| get = lambda self: self.pop(0)

Sorry, to me this is a foolish use of lambda as it is exactly the same as

def get(self): self.pop(0)

except that in the latter, the resulting function object gets a proper
internal name instead of '<lambda>', therefore giving a more informative
traceback in case of an exception.

def get(self): self.pop(0)

Better use

def get(self): return self.pop(0)

otherwise you will *get* nothing

BTW I wonder why a destructive operation is named *get* instead of
*take* ?
