This if statement is equivalent to “If temperature is greater than 30 (i.e. Using these as building blocks, you can start to put together more complicated tests: We can use it to test if the temperature is colder (i.e. The not operator can seem a little confusing at first, but it just reverses the truth value of a condition.
#Python not equal in if statement code
If both conditions evaluate to True, the indented block of code directly below will still be executed. Notice that or only requires one condition to evaluate to True. To show this, we’ll reduce the temperature and use the or comparison operator: The or operator requires only one condition to be True. So, let’s create another variable and test if it’s above a threshold: To implement these, we need a second condition to test. not – Reverses the Boolean value returns False if the statement is true, and True if the statement is false.or – Returns True if at least one of the statements is true.
and – Returns True if both statements are true.There are three possible logical operators in Python: If we want to join two or more conditions in the same if statement, we need a logical operator. As you can see from the code, it’s quite like the written sentence! Logical Operators This example is equivalent to writing “If the temperature is greater than 25, print the word “Warm”. The condition evaluates to true, which then executes the indented block ( print('Warm')). In the next line, we test if this value is greater than 25, which returns the Boolean value True. Here, we set the variable temperature = 35. Now let’s try evaluating an example condition: Note that the equals comparison operator ( = ) is different from the assignment operator ( = ). The if statement in Python takes the following form:īefore we go further, let’s take a look at the comparison operators. Part 2 of Python Terms for Beginners is also a worthwhile read when you’re just getting started with programming. If you’d like to learn the details of Python’s if statements, you’ll find more in this article on Python terms for beginners. The condition must evaluate either True or False.
If so, the indented block of code directly under the if statement is executed. The starting point for handling conditions is a single if statement, which checks if a condition is true. For those of you who are new to Python, consider taking our Python Basics course it will kickstart your programming journey and give you solid foundational skills in Python. This makes Python a great language to learn for beginners. This is especially true for conditional statements, which can almost be read like an English sentence. Python has a simple and clear syntax, meaning the code is easy to read and interpret.
