The key word there is "probably". If there's any chance it
could be not a bug, it can't be an error. At most it should
be a warning, and that's what
Python doesn't care what an expression returns.
You've written an expression that returns the value of the 'clear' function
that is bound to that particular list.
The interpreter doesn't know or care if accessing that 'clear' attribute on
the class returns a function or for some reason triggers

Because it's an expression, and you're allowed to execute expressions.
To put it a bit more clearly, you're allowed to evaluate

Because it's an expression, and you're allowed to execute expressions.
To put it a bit more clearly, you're allowed to evaluate
an expression and ignore the result.

In code, list.clear is just ignored.
At the terminal, list.clear shows
in code:
x = [1,2,3]
x.clear
print(len(x))
3
at terminal:
x = [1,2,3]
x.clear
print(len(x))
3
Caused me an hour of frustration before I noticed list.clear() was what
I needed.
x = [1,2,3]
x.clear()
print(len(x))
