bool class
There's also a built-in function known as bool(), which converts a given value into a boolean value (i.e. either True or False). It's also good to know that almost anything as an input to this function would output True, unless the input is taken from the following:
- {} (empty dictionary)
- [] (empty list)
- () (empty tuple)
- set() (empty set)
- "" or ''
- None
- 0
- 0.0

Like engineers, they design things, assembling components into systems and evaluating tradeoffs among alternatives. Like scientists, they observe the behavior of complex systems, form hypotheses, and test predictions.
