This method will arrange the list in alphabetical order, or it can also be said that it sets the list according to ascending order. Output: We see how the entire list is reversed here. This method returns a reversed iterator object. This method reverses the sorting order of the list. This method takes 2 arguments, first the index and the second, the element that has to be positioned at that index. This method returns the element which has to be inserted at a specified position. This method returns the position of the occurrence of the particular element. Output: Grocery list is the concatenated list of the above ‘fruits’ and ‘vegetables’ list. We shall see this simple join in the step below: The list has append() and extends the () method to concatenate or join two lists, but the ‘+’ operator can also perform this action. Then the second list forms the extends the first list. We add the elements to the end of the list here with the help of another list. Returns to us the number of elements in the list with a specified value. Output: The del list deletes the list, and we get the following output. There is also a ‘del’ keyword that clears the list. To remove the element from the list, we have removed the () method, a pop() method, which we have discussed. This removes all the elements from the list, and it will present you with a list clear of all elements.

We shall discuss here other methods that can be used. We have come across append(), pop() and remove() previously. We have a list of underlying methods that can be used over the list and arrays. We can also use the remove() method and mention the particular element that can be removed. Output: As pop(1) represents the second element from the list. Here we can be specific about the deletion of any particular element by referring to the index. Removal of any element can be done via the pop() method. If one has to append to the list, then it is possible using ‘append()’ We use ‘for in’ while looping through the array. Looping through the array element is also an easy task. We can even return the length of an array by using the len() method. In this case, that last most element will have an index of -1 the second last will be -2, the third last will be -3, so on and so forth.

We can even access a particular element by referring to an index. Another feature of the list is it allows duplicates. When there is a need for order and a requirement of frequent change, we prefer selecting the list. Lists of String Array in Pythonīelow are the lists of a String array in Python: 1. Square brackets are used to access the elements of the String. A single character in itself is a string with length 1. It is to be noted that Python does not have a character data type. Python lists are used to serve the purpose, so we will look into Lists. Python does not have built-in support for Arrays.
