If the new element is empty, the pass statement will get executed and the True part of the if-block will not do any operation and the control will move to the next line. Therefore, I have used the pass statement. If the new element is empty, it should not be added. Now I have added second validation that will check if the new element is empty or not. The first validation is to check if the element is already present in the list. list1 = Įlement = input('Enter the employee ID: ') Consider the example that we discussed in the above section.

Now let us see how to use it with the if-else statement. For example, defining the function and writing its functionality later. This statement is generally used when you do not want to write any part of the code. When the interpreter reads this, it performs no operation. In such situations, you can use the pass statement.

You may face a situation when you want to use an if-else statement, but don’t want to execute any code inside the if or else block. Read: Get index Pandas Python Python if not do nothing Raise an error if the element is not in listĪs you can see in the output, an exception is raised when the supplied value is not found in the list. The entered alphabet is compared with the vowels in the list and the result is returned accordingly. I have defined a list to store all the vowels.The above program will take an alphabet as an input and return the output telling if the entered alphabet is a vowel or a consonant.Print('The entered alphabet is a consonant') You can use the “ not in” operator for the list to check if an item is present in a list or not.įor example, look at the Python code below: list1= In this section, I will explain how you can check if an item is stored in a list or not in Python. Print('The number is even') Python if not in list If you want to use the not operator with if-else, the above becomes: number = int(input('Enter a number: ')) In this way, you can use the not equal to operator to compare the integers. As a result, the False part of the if-else statement is executed. The “ if variable is not None” statement is equivalent to boolean False. I have used “ is not” to check if the variable contains a None value or not. In the above code, we are comparing the variable with the None value. So we have to check if a variable contains a None value or not. In Python, there is None instead of Null.

Therefore, when I executed the above program and didn’t give any input, the True part of the if-else statement worked.Īnd when I executed the program again with a user input, the False part of the if-else statement worked.Īlso, check: Download zip file from URL using python Python if not equal to null In the above example, if the variable is empty, it will satisfy the If-not statement and the True part of the statement will get executed.
