Now let us take an example for each case : Use of else clause: Then, you can use the elif clause and specify any number of situations. Now, suppose you have multiple if conditions and an alternative for each one. Suppose your ‘ if’ condition is false and you have an alternative statement ready for execution.

When we have maintained the indentation of Python, we get the output hassle-free. The color variation happens because of the abrupt indentation of 'print.' All the other text is green, while 'print' has the color red. "Īlso, note the color of 'print' in line 3. We can see here that Python delivers an error message as: "Expected an indented block. Let's take an example where we intentionally differ from the proper indentation: Python will automatically change the text color if you deviate from this indentation and display an error when you run your code. The statements under 'if' are considered a part of one 'block.' The other statements are not part of the if block and are not considered when statements of 'if' are evaluated. The correct indentation syntax of the if-else statement is given as follows: We have to maintain proper indentation and blocks while we write composite statements like if-else. Python is very careful of the syntax of programming statements. For example, when your condition is the same as one of the expressions, you probably want to avoid evaluating it twice: Nevertheless, there are situations when it's better to use 'and' or 'or' logic than the ternary operator. As a workaround, lambdas can help:Īnother approach is using 'and' or 'or' statements: The problem of such an approach is that both expressions will be evaluated no matter what the condition is. We can see that for various inputs, the same output is obtained for the exact value of the variable.

These are various ways to impose conditions in your code : They are generally discouraged, but it's good to know how they work: The compiler evaluates conditions from left to right, which is easy to double-check with something like the pprint module:įor Python versions lower than 2.5, programmers developed several tricks that somehow emulate the behavior of the ternary conditional operator. This command is the same as the program given below : This form is the chained form of ternary operators. Here we have incorporated multiple conditions. We can chain the ternary operators as well: Now let’s see what the output is:Īs we can see, we have obtained the output as “kid” based on the value of the age variable. We have mentioned this condition in the if-else command. The condition for being an adult is that the person’s age should be eighteen or greater than that. Now we use the if-else command to print if the kid is an adult or not. Here we have defined the age variable whose value is fifteen. Evaluation is lazy, so only one expression will be executed. It first evaluates the condition if it returns True, the compiler will consider expression1 to give the result, otherwise expression2. So, when PEP 308 was approved, Python finally received its shortcut conditional expression: Moreover, the colon already has many uses in Python.

The Python BDFL (creator of Python, Guido van Rossum) rejected it as non-Pythonic since it is hard to understand for people not used to C. Programming languages derived from C usually have the following syntax: In other words, it offers a one-line code to evaluate the first expression if the condition is true otherwise, it considers the second expression. The most common usage is to make a terse, simple dependent assignment statement. Many programming languages have a ternary operator, which defines a conditional expression. So let’s begin our discussion on conditional statements, their syntax, and their applications. Luckily, Python has a straightforward command and syntax to solve such kinds of problems. You will encounter various coding problems where you will have to print the output based on some conditions. These conditions control the coding world as well. But if it isn’t, you will have to cancel your plans. If the weather is pleasant, you can make plans for an outing. A twelve-year-old person is a kid, whereas a thirteen-year-old person is a teenager. In the real world, there are specific classifications and conditions on every action that occurs around us. Last Updated: Thursday 30 th December 2021
