![]() ![]() There's something satisfying to me about having a unified style regardless of whether or not you use an intermediate variable for your condition. Finally, I like how this style lends itself very naturally to refactoring the condition into its own variable, like so: This makes it easy to see the history with git-blame. And I also like how adding or removing clauses from the condition will only change a single line, (unless you remove the first condition, "some_super_long_condition"). It looks visually pleasant, (at least to me). MULTIPLE OR STATEMENTS PYTHON CODEWhat are some of the "advantages" of this style? Well, for one, I like how the code for the condition, True, and False branches all line up. But to be honest, most of the styles I've seen-even those that conform with the PEP-seem ugly and hard to read for me. Consider the following python code.PEP 8 gives a number of acceptable ways of handling multiple line if-statements in Python. To execute the statement or function for a particular case, you can use the get() method of the Python dictionary. You can also implement the case statement in Python using dictionaries. Read: Python string to list Case statement dictionary Python ![]() In this way, you can define a default case in a switch case implementation in Python using the if-else statement. You can see that the default case value is returned. This time I am passing 13 as the case value. I have implemented the same program with a default case: def printMonth(num): However, you can define a default case in an else section. If a person enters a number except from 1 to 12, the program will throw an error. Take the example of the program that we executed in the above section. While implementing the switch case statement in python using the if-else statement, you can define the default case value in the last else section of the program. Read: Python dictionary extend Python switch case default value In this way, you can use the if-else statement to implement the case statement in Python. Similarly, we have defined all the cases from 1 to 12 in the function. You can see that we supplied the number 10 as the input and the function returned October. ![]() The function returned the expected month name Input is an employees first name, last name, salary, and numeric. In the above function, we are assigning the name of the month in every if block according to the specified number. Summary In this lab, you complete a Python program that calculates an employees annual bonus.But, let us see how we can implement this with the help of an if-else statement. In this case, you may want to use the case statement. For example, 1 to 12 represents the months of the year from January to December. Suppose you want to print the month’s name of a year according to a specified number. The idea behind this method can be understood with the example below. Let us discuss some methods with examples to implement the case statement in Python.Īlso, Read: Python dictionary of lists Simple case statement in PythonĪs explained above, we can use multiple if-else blocks to implement a case statement in Python. The keys will be your conditions and the corresponding values will be the functions that you want to call according to the condition. Python return multiple values, return null, return list, return keyword. You can make a dictionary and make key-value pairs of cases and functions. Python return statement terminates the function and return the value to the caller. The second method is to map cases with some functions using dictionaries in Python. In that case, you have to use multiple if-else statements for multiple cases. If either of the three expressions is True, the print function inside the if statement should display the message. The OR operator is used twice in the if statement to evaluate three expressions. For demonstrating this, I have declared and assigned values to three variables. You may evaluate more than two expressions by using the OR operator. In Python, you can implement the case statement in many ways. Hope it clears how Python OR operator works. MULTIPLE OR STATEMENTS PYTHON HOW TORead Remove non-ASCII characters Python How to use case statement in Python? ![]() Hence, in this article, I will explain how you can create functions in Python that you can use as the case statement. However, we can make our own functions that we can use as an alternative to the case statement. But, in Python, there is no case statement by default. Most of the languages support the case statement. Python switch statement best practices Does Python have a case statement? ![]()
