(This is a fast technique, as it is pretty straightforward, and does not involve any searching of an item in the list.) Python del operator: Since there is no element at this position, the python interpreter throws an Inde圎rror as shown in output. In Example 3, we use the pop() to remove the element which is at index position 8. Note that, in Example 2, when we print the list myList after calling pop(), the integer 11, which was previously present in myList has been removed. As you can see from the output, the pop( ) removes the element, and returns it, which is the integer ‘ 11 ’. In Example 1, we are using the pop( ) method, while passing the argument ‘ 1’, which is nothing but the index position 1. In this example, we are defining a list called ‘ myList ’. If the particular item to be removed is not found, then an Inde圎rror is raised. But, when using the pop(), we specify the index of the item as the argument, and hence, it pops out the item to be returned at the specified index. The difference between this method and the remove() method is that, we should specify the item to be removed in the remove() method. This method removes an item or an element from the list, and returns it. The pop() method is another commonly used list object method. (However, this is a slow technique, as it involves searching the item in the list.) List Object’s pop() method: As a result, a ‘ ValueError ’ is thrown by the Python interpreter. But, we know that the list ‘ myList ’ does not have the integer 44. In Example 2, we use the remove() to remove the element 44. ValueError: list.remove(x): x not in list2 Hence, when printing the list using the print(), we can see that the element 22 has been removed from myList. In Example 1, we are using the remove() method to remove the element 22 from myList. Note that, as discussed before, we are enclosing the list literal within square brackets. ![]() In this example, we are defining a list called ‘myList’. If the particular item to be removed is not found, then a ValueError is raised. We can consider this method as “removal by item’s value”. Note that, if there are multiple occurrences of the item specified, then its first occurrence will be removed from the list. When you use this method, you will need to specify the particular item that is to be removed. The remove() method is one of the most commonly used list object methods to remove an item or an element from the list. There are three ways in which you can Remove elements from List: Now that you have a clear idea about how you can actually create lists, let’s move on to see, how to Remove Elements from Lists in Python. In this way, we can store elements of different types in a single list. ![]() This list is an ordered sequence that contains elements of different data types.Īt index 0, we have the string element ‘Bran’.Īt index 2, we have a floating-point number 3.14. and each element is separated by a comma. As you can see, all the elements are enclosed within square brackets i.e. In the above example, we have defined a list called ‘ myList ’. All the elements in a list are enclosed within ‘square brackets’, and every element in it are separated by a ‘comma’. Lists are also very useful to implement stacks and queues in Python. The main reason why lists are an important tool in Python Programming is because of the wide variety of the built-in functions it comes with. In addition to this, lists can be nested as well i.e. Lists are also mutable, which means, they can be altered after creation. Lists support indexing and slicing, just like strings. A single list may contain data types like strings, integers, floating point numbers etc. Arrays contain elements of the same data types, whereas Python lists can contain items of different types. We can compare lists in Python to arrays in other programming languages. In other words, a list is a collection of elements which is ordered and changeable. ![]() ![]() Lists are ordered sequences that can hold a variety of object types. Now that you know how important lists are, let’s move on to see what exactly are Lists and how to remove elements from list! What are Lists? With its list collection data type, we can store elements of different data types as a single ordered collection! In simple words, if you define an array of type integer, you can only store integers in it. Now, this is fairly impossible with the default data types that are available in other programming languages like C & C++. For example, let’s say, you need to have a string type element, an integer and a floating-point number in the same collection. Sometimes, there may be situations where you need to handle different types of data at the same time.
