We use the“and”operator to check whether multiple variables’ values are default values. In Python, if a variable contains a default value, it returns False, but here, we are using theNot operator, so it will become True and execute the if statement block of code. How to use the Not...
The operator module in Python provides various methods like addition, subtraction, exponentiation, left shift, right shift, etc. One among these many methods is not_(). It returns the negated value of the argument provided to it.import operator initial_list = [False, True, True, False] prin...
In the first example, Python evaluates the expression True == False and then negates the result by evaluating not.In the second example, Python evaluates the equality operator (==) first and raises a SyntaxError because there’s no way to compare False and not. You can surround the ...
The Not Equal operator (!=) in python is used to check if two values are not equal. If they are not equal, True is returned, otherwise False is returned. We can use this operator in conditional statements, and looping statements like for, while loop etc. We can also use this operator...
Example 1: if not – Boolean In this program, I will use Python Example not logical operator in the boolean declaration of Python Example IF. Program flag = False if not flag: print('flag is false.') Results flag is false. Example 2: Python if not – String ...
In Python, the "not equal" operator is used to compare two values and determine whether they are not equal to each other. It is represented by the symbol !=. The result of the comparison is a Boolean value: True if the values are not equal, and False if the values are equal. ...
6. Using == OperatorThe == operator is used to test equality between two values. It returns True if the values are equal, and False if they are not. You can use the == operator to compare values of any type, including integers, floats, strings, and objects. In the below example, ...
3. NameError name is not defined in Python 3 by providing default values: If the variable might not exist but still needs a value, we can use theget() methodfor dictionaries or provide default values using theor operatorin Python.
Example: SQL IN -- select rows if the country is either USA or UKSELECTfirst_name, countryFROMCustomersWHEREcountryIN('USA','UK'); Run Code Here, the SQL command selects rows if thecountryis either theUSAor theUK. Example: SQL IN Operator ...
