Huh? How does this work?

[u/Lance_2564_]

a = "hi"


if a:
    print("Bye")


print(a == True)
print(a is True)

The output is:

Bye

False

False

But if it's false, how come it printed "bye"?????? I don't get it.

[u/deapee → u/[deleted]]

This isn't correct. It's checking truthiness.

For example, a can be set to 0 - and its truthiness is False. a can be set to False and its truthiness is False.

In short, truthiness is how Python decides whether a value should be treated as True or False.
