Relational Operators<\/h2>\n
\n\n
Relational Operators<\/h3>\n
Relational operators in Python are used to compare values and determine the relationship between them. These operators return Boolean values (True<\/code> or False<\/code>) based on the comparison result. Here are the relational operators in Python:<\/p>\n\n\n\n\n\n\n\n\n\n\n
Operator<\/th>\nDescription<\/th>\nExample<\/th>\n<\/tr>\n<\/thead>\n
==<\/code><\/td>\nEqual to<\/td>\n5 == 5<\/code><\/td>\n<\/tr>\n
!=<\/code><\/td>\nNot equal to<\/td>\n5 != 3<\/code><\/td>\n<\/tr>\n
><\/code><\/td>\nGreater than<\/td>\n7 > 3<\/code><\/td>\n<\/tr>\n
<<\/code><\/td>\nLess than<\/td>\n2 < 4<\/code><\/td>\n<\/tr>\n
>=<\/code><\/td>\nGreater than or equal to<\/td>\n6 >= 4<\/code><\/td>\n<\/tr>\n
<=<\/code><\/td>\nLess than or equal to<\/td>\n3 <= 3<\/code><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
These operators can be used to compare numeric values, strings, variables, or expressions. The result of the comparison is a Boolean value indicating whether the comparison is true or false.<\/p>\n
Examples<\/h3>\n
<\/p>\n
\n
x =<\/span> 5<\/span>\r\ny =<\/span> 7<\/span>\r\n\r\nprint<\/span>(x ==<\/span> y)   # False<\/span>\r\nprint<\/span>(x !=<\/span> y)   # True<\/span>\r\nprint<\/span>(x ><\/span> y)    # False<\/span>\r\nprint<\/span>(x <<\/span> y)    # True<\/span>\r\nprint<\/span>(x >=<\/span> y)   # False<\/span>\r\nprint<\/span>(x <=<\/span> y)   # True<\/span>\r\n<\/pre>\n<\/div>\n\n<\/div>
Logical Operators<\/h2>\n
\n\n
Logical Operators<\/h3>\n
Logical operators in Python are used to combine or manipulate Boolean values (True<\/code> or False<\/code>). These operators allow you to perform logical operations and make decisions based on multiple conditions.<\/p>\n\n\n\n\n\n\n\n
Operator<\/th>\nDescription<\/th>\n<\/tr>\n<\/thead>\n
and<\/code><\/td>\nReturns True<\/code> if both operands are True<\/code><\/td>\n<\/tr>\n
or<\/code><\/td>\nReturns True<\/code> if at least one operand is True<\/code><\/td>\n<\/tr>\n
not<\/code><\/td>\nReturns the opposite Boolean value of the operand<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
These operators are used to combine or manipulate Boolean values and are commonly used in conditional statements, loops, and Boolean expressions.<\/p>\n
