Operators in Python

In python, following operators are generally used:

1.      Comparison Operator

2.      Logical Operator

1.      Comparison Operator:

In Python, there are following types of comparison operators:

                    i.            Less than (< ) Operator

                  ii.            Greater than (>) Operator

                iii.            Less than or Equal to (<= ) Operator

                iv.            Greater than (>=) Operator

i.                    Less than (< ) Operator:

·         It checks left value is less than that of right value. If it is less then output is true otherwise output is false.

·         For example:

>>> 1 < 2

      Output is true, because 1 is less than 2.

      Suppose consider another example:

>>> 4 < 2

     Output if false, because 4 is not less than 2.

ii.                  Greater than (>) Operator:

·         It checks left value is greater than that of right value. If it is greater then output is true otherwise output is false.

·         For example:

>>> 2 > 1

      Output is true, because 2 is greater than 1.

      Suppose consider another example:

>>> 2 > 4

     Output if false, because 2 is not greater than 4.

iii.                Less than (<= ) Operator:

·         It checks left value is less than or equal to that of right value. If it is less or equal then output is true otherwise output is false.

·         For example:

>>> 1 < = 4

      Output is true, because 1 is less than 4.

      Suppose consider another example:

>>> 2 <= 2

     Output if true, because 2 is equal to 2.

iv.                Greater than (>= ) Operator:

·         It checks left value is greater than or equal to that of right value. If it is greater or equal then output is true otherwise output is false.

·         For example:

>>> 4 > = 1

      Output is true, because 4 is greater than 1.

      Suppose consider another example:

>>> 2 >= 3

     Output if false, because 2 is not greater or equal to 3.

2.      Logical Operator:

Following table describes the Logical Operators in Python:

Sr. No.	Operator	Meaning	Example
1	AND	If both the operands are true then condition becomes true otherwise false.	(x and y) is False.
2	OR	If any of the two operands are non-zero then condition becomes true otherwise false.	(x or y) is True.
3	NOT	Used to reverse the logical state of its operand.	Not(x and y) is True.
