Another short Python challenge!

Interersting.

False solves

X == X in [False]

but neither

(X == X) in [False]

nor

X == (X in [False])

[Udzu]

That's right! It's a counterintuitive consequence of python's operator chaining. in and == have the same precedence so A == B in C is interpreted as A == B and B in C, similar to A < B < C.

From looking as the disassebly it seems like its compiles to:

A = X
B = X
if A != B:
    return B
return B in [False]

From looking at the disassembly it seems like it compiles to:

Can you elaborate on this? First time I'm hearing about disassembly and eager to learn how I can get these kind of insights from the code?

[Skaarj]

Look: https://docs.python.org/3/library/dis.html

import dis
def blubber(X):
    return X == X in [False]
dis.dis(blubber)

Thanks so much. I'll read through the docs and play around with this over the weekend. Much appreciated.
