Chapter 4.1, Problem 4.5CP

Boolean expression:

• The Boolean expression evaluates the statement and returns either “True” or “False” with the help of “if” statement.
• The relational operator is used to form the Boolean expression that is tested by an “if” statement.
• Some of the relation operators used in Boolean expression are “>” “<”, “==”.

Relational Operators:

Relational operators are used to compare numeric and character values using the following operators and the operator makes a relationship between the two operands.

• Greater than (>)
  • The relational operator “>” is used to compare two operands and checks whether one operand is greater than the other.
  • Example

    if a>b

print(“a is greater”)

• Less than (<)
  • The relational operator “<” is used to compare two operands and checks whether one operand is less than the other.
  • Example

    if a<b

print(“a is lesser”)

• Greater than or equal to (>=)
  • The relational operator “>=” is used to compare two operands and checks whether one operand is greater than or equal to the other.
  • Example

if a>=b

print(“a is greater than or equal to b”)

• Less than or equal to (<=)
  • The relational operator “<=” is used to compare two operands and checks whether one operand is lesser than or equal to the other.
  • Example

if a>=b

print(“a is lesser than or equal to b”)

• Equal to (==)
  • The relational operator “==” is used to compare two operands and checks whether two operands are equal...
