Why are Python lambdas useful?

Question

I'm trying to figure out Python lambdas. Is lambda one of those "interesting" language items that in real life should be forgotten? I'm sure there are some edge cases where it might be needed, but given the obscurity of it, the potential of it being redefined in future releases (my assumption based on the various definitions of it) and the reduced coding clarity - should it be avoided? This reminds me of overflowing (buffer overflow) of C types - pointing to the top variable and overloading to set the other field values. It feels like sort of a techie showmanship but maintenance coder nightmare.

I totally get where you're stuck at. I was as well while learning python.

The significance of lambda functions is their ability to called and then forgotten by the memory. In this contrast when you define a function and then call it, it requires memory and when programs are scaled this can cause less optimization. whereas lambda function are just used and then forgotten like disposable pottery.
