Text in quotes are treated as Strings, while “True” or “False” without the quotations are treated as Boolean variables. They are different data types.

Strings are “string of text” that could be “printed” (output) to the screen, while Booleans are just variables used to store “yes” or “no”. For example:

print "True"

will output “True” (without quotes) to the screen, while

print True

will not. And

x = True
if x == True:
    print "x is true"
else:
    print "x is not true"

will print “x is true” (without quotes) to the screen, while

x = "True"
if x == True:
    print "x is true"
else:
    print "x is not true"

will print “x is not true” (without quotes) because the data type is different.

The system should not let you pass if you put quotes around “True” and “False”, but Codecademy still have some flaws and sometimes does that.

Should be true, anyway

the quotation marks must confuse the computer
