A small clarification needed Is it right?

a="false" b="true" print(a and b) output is true and why?

They are both strings objects. a and b will return true if both objects are not None Note the difference: a=False b=True print(a and b) // outputs False

Every value or object which is not None and False is a "truthy" value. Every "truthy" value is evaluated as True. False is different from the object string "false". Because both a and b are strings, they are truthy and they evaluate as True.

Not exactly true @Gami, this is python, not Ruby "" aka the empty string is considered false [] aka the empty list is also considered false 0 also
