Python List Remove

Remove element from a Python LIST [clear, pop, remove, del]

The Python List data-type enables you to organise and store objects with varying data types in a hierarchical structure. The information is presented in the form of square brackets ([]), and each value is denoted by a comma (,).

Python’s list data type makes available a large number of methods that can be used to assist in the process of removing an element from a given list. delete(), pop(), and clear() are the methods that are available.

When you want to remove items from a list, in addition to the list techniques, you may also use a del keyword.
A sample entry from the list my list would look something like this: [‘Guru’, 50, 11.50, ‘Siya’, 50, [‘A’, ‘B’, ‘C’]]
The index begins at 0 in this case. At the top of the list: my list at

At the 0th index, the string “Guru” can be found.

You will obtain the integer number 50 when you are at the index position 1.
You will find the floating number 11.50 when you go to index:2.
There is a string that reads “Siya” located at index:3.
You will see that the number 50 appears twice in the index:4 location.
You will obtain a list with the values A, B, and C when you reach index:5.
The delete() function in Python
Python’s built-in removes () method is one of the possible methods for use with the list. It is helpful to eliminate from the list the item that corresponds to the specified very first element.

The element that you want to remove from the list, as specified by the list.remove(element) syntax.

Python remove() method

This procedure does not produce any sort of return value.

Some helpful hints for the delete() method:
When utilising the delete () method, the following are the crucial considerations to keep in mind:

In the event that the list contains elements that are identical to one another, the very first element that satisfies the criteria for removal from the list will be carried out.
If the specified element does not appear in the list, an error message indicating that the element does not appear in the list will be thrown.
It is not possible to get a value back from the delete () method.
Since the value is used as an argument when using remove (), the value must be of the appropriate datatype for the function to succeed.
Example: Employing the remove() function to eliminate one of the items from the list
I’ve included an example list that I’ve compiled here.

my list = [12, ‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’]
The list contains items of both the string and numeric kinds for the dates. There are duplicate items in the list, such as the number 12 and the string “Riya.”

my list = [12, ‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’]
my list.remove(12) # This command will get rid of the element 12 at the beginning of the list.
print(my list) \smy list.remove(‘Riya’) The number “#” will take the first Riya from the list.
print(my list) \smy list.remove(100) #will produce an error when trying to print (my list)
Output:

[‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’]
[‘Siya’, ‘Tiya’, 14, 12, ‘Riya’]
The most recent call comes in last for the traceback.
Line 9 in the “display.py” file, under the “module” folder
my list.remove(100)
Error message from list.remove(x): x is not present in the list
The pop() function in Python
The pop() method will delete an element from the list based on the index that is provided in its argument.

Syntax \slist.

index is the sole argument that can be passed to the pop() method, which is named index.

You will need to pass the index of the element that you want to remove from the list in order to do so. The index begins at 0 in this example. To obtain the item at the beginning of the list, enter 0 as the index. You can eliminate the very last piece by passing the index as the value -1.
The index argument is not required to be used. In the event that it is not passed, the default value is thought to be -1, and the last member from the list is returned.
The pop() method will provide an error message that reads “IndexError: pop index” if the specified index does not exist or falls outside the acceptable range.
ReturnValue:

The element that was removed will be returned by the pop() method based on the index that was specified. The final list has also been amended, and the element has been removed from it.

In this example, we will delete an entry from the list by employing the pop() technique.
my list = [12, ‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’] is the list that will be utilised in the illustration.

Let us make an attempt to get rid of the element by using the pop() method based on the following:

By giving index
Not having an index
Providing an index that is outside of the allowed range.
At this point, we will scratch Tiya’s name off the list. Because the index begins at 0, Tiya has a value of 2 in the system.

my list = [12, ‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’]

#By providing the index value 2 in order to remove Tiya from my list.

pop(2)
print(name) \sprint(my list)

#pop() method without an index will return my list’s element that was most recently accessed.

pop() \sprint(item) \sprint(my list)

item = my list has been passed an index that is out of range.

pop(15) \sprint(item)
print(my list)
Output:

Tiya [12, ‘Siya’, 14, ‘Riya’, 12, ‘Riya’]
Riya [12, ‘Siya’, 14, ‘Riya’, 12]
The most recent call comes in last for the traceback.
Line 14 in the “display.py” file, under the “module” folder
item equals the my list.pop file (15)
IndexError: popindex is too high for this range
Python clear() method
The clear() method will get rid of any and all of the elements that are currently in the list.

Syntax: \slist.clear() \sParameters:

No parameters.

ReturnValue:

There is no value that is returned. Using the clear() technique, the list() variable is made empty.

Example: removing all of the elements from the list by employing the clear() technique
The clear() method will delete all of the items in the specified list. Let’s take a look at the sample below to see how the clear() function works:

my list = [12, ‘Siya’, ‘Tiya’, 14, ‘Riya’, 12, ‘Riya’]

#Invoking the clear() method with the element set to my list

clear() \sprint(element) \sprint(my list) \sOutput:

None \s[]
Using del keyword
You can remove an item from the list by using the del keyword followed by a list. This will accomplish the desired result. You are need to supply the list the index of the element in question. The index begins at 0 in this example.

Syntax: del list[index]
Using the keyword “del,” it is also possible to remove a set number of elements from the list. You can supply the start and stop indexes from the list to the del keyword, and the components that fall within that range will be erased from the list. The following is the correct syntax:

Syntax: destroy list

[start:stop]
Deleting the first element, the last element, or numerous entries at once from a list can be demonstrated with the help of the following example.
