if condition 2 is trueĭisp ( ' c is maximum ' ) -if condition 2 is false In this example, we will see a maximum of three numbers, let us consider three numbers a, b and c. Screen 2: Matlab implementation of example 2 Example #3 – Use of Nested if Statement Screen 2 shows the Matlab implementation of example 2. Let us take two number ‘ a ’ and ‘ b ’.ĭisp ( ' a is maximum ' ) - condition 1 is trueĭisp (' b is minimum ' ) -condition 1 is false Screen 1: Matlab implementation of example 1 Example #2 – Comparison of Two NumbersĬonsider the second example to find out the maximum of two numbers. However, if the first operand is True, it concludes that the output is True without even checking the second operand.Screen 1 shows the Matlab implementation of example 1. So, if the first operand is False only then it evaluates the second operand. It works similarly for the OR operand where Python first checks the first operand. As we know, the OR logical operator returns False only if both of the operands are False. Hence, Python needs to evaluate the second operand as well.
In the above example, as the first operand is True we cannot determine the result for the “ and” operation. However, let’s look at a different situation- def check(v): The first operand, in this case, was False hence Python did not evaluate the second operand. As we know the AND operator returns False, if one of the operands is False. In the above example, only one print statement is executed, i.e., Python evaluated only the first operand. Look at the following example: def check(v): This means that it first evaluates the first operand, and if only the first operand defines the result, then the second operand is not evaluated at all. While you have to use symbols like “ &” and “ ||” in some other languages like C++ and Java, Python makes life easy for you by providing direct words like “ and”, “ or“, etc which make more sense and resemble normal English.įurther, logical operators (in most languages) have the advantage of being short-circuited. Python is a way more user-friendly language. Print("Either of the numbers is positive")Įither of the numbers is positive The Python Advantage of Logical Operators Print("The numbers are positive numbers") Let’s look at an example to understand this: # functioning of Logical and operator However, if any one of the two operands is False, then it returns False. The Logical AND operator is used to return True if both operands are True. Returns True if the single operand is False, otherwise returns False. Returns True if one operand is True, and otherwise it returns False. Returns True if both operands are True, and False otherwise. The logical operators in Python are used on conditional statements, i.e, either True or False. They carry out arithmetic and logical computations. What are Operators in Python? Operators are the special symbols that are used to perform operations on the variables and values. 👉 Instant Fix: Replace the & operator with and, which will solve the issue. Hence, when Python comes across “ &” in the program, it is unable to identify the operator and deems it as invalid. Python does not have the provision for the & operator.
We encountered the syntax error because of the usage of & operator in our code. Why? The answer is not as difficult as you might have thought.
You have got the logic right, yet there’s an error. Output: You will get the following error inside the “if” statement. Print("The lists has even number of elements")Įlif len(num_1) % 2 != 0 & len(num_2) % 2 != 0: Problem: What is the equivalent of &(logical-and) in Python?Įxample: Let’s have a look at the following example: num_1 = Using & will raise a Synta圎rror, so use and instead! Overview In Python, the equivalent of & (logical-and) in programming languages such as C++ or Java in an if-statement is and.
