What does the expression 9.2 not in myNumbers return if 9.2 is present in the list?

The expression "9.2 not in myNumbers" evaluates whether the value 9.2 is absent from the list named myNumbers. If 9.2 is actually present in that list, the expression will return False. This is based on the semantics of the in operator in Python, which checks for membership.

When using the not in operator, if the value is found in the list, the negation of True (which is True that the value is in the list) results in False being returned. Essentially, the statement "9.2 not in myNumbers" indicates that 9.2 is not part of the collection, and if it is, the logical implication is that the expression's conclusion must be False.

Consequently, the correct understanding of boolean logic in Python leads us directly to this result when the value exists within the specified list.
