Case 1: Python evaluates true_func(), which returns True. To determine the final result, Python evaluates false_func() and gets False. You can confirm this by seeing both functions’ output. Case 2: Python evaluates false_func(), which returns False. Python already knows that the final result is False, so it doesn’t evaluate true_func(). Also called formatted string literals, f-strings are string literals that have an f before the opening quotation mark. They can include Python expressions enclosed in curly braces. Python will replace those expressions with their resulting values. So, this behavior turns f-strings into a string interpolation tool.Python lists store multiple data together in a single variable.
