<1> compare (that is, relational) operators

The comparison operators in Python are the following table

operator Description Example
== Checks whether the values of the two operands are equal, and if so, the condition becomes true. If a=3,b=3 (a = = B) is true.
!= Checks whether the values of the two operands are equal, and if the values are not equal, the condition becomes true. True if a=1,b=3 (a! = b).
<> Checks whether the values of the two operands are equal, and if the values are not equal, the condition becomes true. True if A=1,b=3 (a <> b). This is similar to! = operator
> Checks if the value of the left operand is greater than the value of the right operand, and if so, the condition is true. True if A=7,b=3 (a > B).
< Checks if the value of the left operand is less than the value of the right operand, and if so, the condition is true. If A=7,b=3 (a < b) is false.
>= Checks whether the value of the left operand is greater than or equal to the value of the right operand, and if so, the condition is true. True if A=3,b=3 (a >= b).
<= Checks whether the value of the left operand is less than or equal to the value of the right operand, and if so, the condition is true. True if A=3,b=3 (a <= b).
<2> logical operators
operator Logical Expressions Description Example
and X and Y Boolean "and"-if x is False,x and y returns FALSE, otherwise it returns the computed value of Y. (A and B) returns 20.
Or X or Y Boolean "or"-if x is true, it returns true, otherwise it returns the computed value of Y. (A or B) returns 10.
Not Not X Boolean "Non"-returns False if X is True. If X is False, it returns TRUE. Not (A and B) returns False
