7,871 PointsMake a variable named right with a value that's truthy. Then make another variable named wrong with a falsey value.
I did like this but I don't know why it is not working
right = "truthy" wrong = "falsey"
even I tried to append it but it is not working.
right = "True"
wrong = "False"

71,830 Points"true" and "false" are Strings, and are not truthy or falsey.
right = 1
wrong = 0
The following are considered false (falsey):
- None
- False
- zero of any numeric type, for example, 0, 0L, 0.0, 0j
- any empty sequence, for example, '', (), []
- any empty mapping, for example, {}
- instances of user-defined classes, if the class defines a nonzero() or len() method, when that method returns the integer zero or bool value False
All other values are considered true.

15,480 PointsSenay: What you did was add a string to each variable by inlcuding the quotes. A string is different than True / False. Try something like this.
'''python right = True wrong = False '''

15,480 Pointsignore the '''python ''' > the markdown did not work apparently. Just use
right = True wrong = False
