Table 7.4: Logical Operators (Assume the value of a, b, and c to be 10, 5, and -2
respectively for computations in the table)
Operator Explanation Examples

and It yields True if both the operands >>> True and True
yield True, and False otherwise. True
>>> True and False
False
>>> a > b and b > c
True
>>> a < b and b > c
False
>>> a < b and b < c
False
or It yields True if either of the two >>> True or True
operands yield True, and False True
otherwise. >>> False or True
True
>>> False or False
False
>>> a > b or b > c
True
>>> a < b or b > c
True
>>> a < b or b < c
False
not Not True yields False and Not >>> not True

False yields True. False
>>> not False
True
>>> not a > c
False
>>> test = 0
>>> not test
True
7.5.5 Identity Operators

Identity operators are typically used for checking the data type of an object. The identity operator returns True if the
operands on either side of the operator are the same object or same type, and False otherwise.
Table 7.5: Identity Operators (Assume that a, b, c have values -2, None, "Hello", respectively)
Operator Explanation Example

is It yields True if the operands on either >>> type(a) is int
side of the operator are the same object True
or same type, and False otherwise. >>> type(c) is list
False
>>> a is b
False
>>> v = a
>>> a is v
True
