mrx = ["elon", "musk"]
varb = ["elon", "musk"]
a = mrx
print(mrx is not a)
# returns False because a is the same object as mrx
print(mrx is not varb)
# returns True because mrx is not the same object as varb, even if they have the same content
print(mrx != varb)
# to demonstrate the difference betweeen "is not" and "!=": this comparison returns False because mrx is equal to varb
