3.2 Lesson Period 2 - None Data Abstraction

None - 3.2.9

print("x = None")
x = None
# Nones are data abstractions because they represent a nonexistent value for better handling of unspecified data.

print("Output of x:", x)
print("So is x true, or is x false?")
if x:
  print("Do you think None is True?")
elif x is False:
  print ("Do you think None is False?")
else:
  print("None is not True, or False, None is just None...")

x = None
Output of x: None
So is x true, or is x false?
None is not True, or False, None is just None...
