When and How to Use AND and OR to your Advantage: A blog on improving your coding skills.
AND is a logical operator, meaning that it can only be used with boolean statements. It returns true if both of the statements are true and returns false otherwise. Let’s look at the following example:
if (age >= 18) && (first_name == “Bob”)
puts “Welcome, Bob!”
end
This will return “Welcome, Bob!” if age is greater than or equal to 18 and first_name equals Bob. If either first_name does not equal Bob or age is less than 18, then the code will not execute and we will receive no output.
OR is also a logical operator but it returns true if either of the two statements is true. The above code could instead be written as:
if (age >= 18) || (first_name == “Bob”)
puts “Welcome, Bob!”
end
In this case, we would receive the same output because first_name equals Bob and age is greater than or equal to 18. However, let’s say that our age was 14 and our name was
When you’re writing code in CS 1110, you need to make sure that your code will run properly and the computer will understand what you want it to do. There are many ways to get it wrong and only one way to get it right.
In this blog, I’d like to focus on the proper use of AND and OR when coding. When I was a TA for CS 1110, one of the most common mistakes that students made was using AND and OR improperly. For example, in a previous blog post, I wrote about how to use if statements in your code. In this blog post, I’ll explain when and how to use AND and OR in your if statements.
Let’s start by looking at the following program:
Python is an object-oriented programming language. It uses a programming structure that is based on objects and classes. Python is used for many different applications. It can be used for web development, data science, desktop GUIs, and more.
The language itself has many built-in functions to make programming in Python easier. Some of the most commonly used built-in functions are print(), int(), float() and str(). The use of these functions can simplify your code and make it more readable.
Python also has a number of logical operators that can be used in conditional statements. These operators include AND, OR, NOT and XOR. These operators are also useful when writing code to accomplish specific tasks.
This article will explore some of the most common uses of the AND operator in Python. We will look at how to use it as a logical operator and we will also look at how to use it as a bitwise operator.
One of the most useful and important operators in programming is the boolean operator. This operator allows programmers to test out a condition and see if it is true or false. The two main boolean operators are AND and OR. What makes these two very important is that they allow for very specific results and can make a program run more efficiently.
AND is used when you need both conditions to be met in order for the code to be executed. For example, let’s say we want to take the average of two numbers only if both numbers are less than 10:
def avg(x,y):
if x<10 and y<10: return (x+y)/2 else: return "not less than 10" When this code is run, the result will be 3 if x=2 and y=5 because both of these numbers are less than 10. If either one of them is not, then it will return "not less than 10". AND is used when both conditions must be met, which in our example above would be that both numbers must be less than 10. The word AND is probably one of the most frequently used words in programming. It is almost used more than Hello World. But how do we use it? What does it do? How can we use it to our advantage? Well, keep reading, and you'll find out! What is AND? AND is a bitwise operator. This means that it will only return a 1 if both of its arguments also return a 1. If either of the two arguments return a 0, then AND will return a 0. You can think of AND as being similar to an intersection, where you have two sets (or groups) and you want to know what elements are only in both sets. You could also describe this as saying "let me select all elements that pass this test AND that test." Here's an example: If we have 4 bits: 0110 & 1101 (binary) == 0100 (binary) == 4 (decimal) The decimal value 4 is returned because only 2 bits made it through both tests: (0110 & 1101) == 0100 The Logical AND Operator (&&) The logical AND operator returns true if both operands are true and returns false otherwise. The following diagram shows how the AND operator works: Operand1 Operand2 Result True True True True False False False True False False False False Notice that the expression in the first row of the table above is only true when both operands are true. This is the case for all four rows. Even if one of the operands is true and the other false, it will return false. For example: if (age > 18 && height < 180) { System.out.println("The person can go."); } else { System.out.println("The person cannot go."); } In this code, we check whether a person can go to a theme park by checking two conditions: age and height. A person has to be older than 18 and shorter than 180 centimeters to go to that theme park. If either of those conditions isn't met, then they cannot go to the theme park.
