List Remove Method

The Remove Module is a built-in listing technique that permits you to delete values in an inventory.

It deletes the primary incidence of a price in a sequence, i.e., it gained’t erase all of the situations if exist in the listing.

The take away() technique has the next syntax:

List_name.take away(<element_value>)

It takes the element_value as an enter argument. The perform searches the listing for the matching element_value and removes the primary incidence of the element_value from the listing.

It doesn’t have a return worth. It solely removes the ingredient from an inventory with out returning a price.

How does the Remove() perform work?

When we pass an enter worth to the take away(), the listing will get iterated via every ingredient till the matching one will get discovered.

This matching ingredient will get eliminated from the listing, and the indexes of all gadgets of the listing get additionally up to date. If an invalid or non-existent ingredient offered as enter, then the perform raises a ValueError exception.

Program Examples

Removing a component from an inventory

List = [1,3,2,4,6]

List.take away(3)

print (List)

The end result is as follows:

[1, 2, 4, 6]

Removing a tuple from the listing

List = [1,2,(4,6),(25,4)]

List.take away((4,6))

print (List)

The output is as follows:

[1, 2, (25, 4)]

Delete a string from the listing

List = ["Unix", "PHP", "Golang"]

List.take away("PHP")

print (List)

The end result is as follows:

['Unix', 'Golang']

Removing a replica parts in an inventory

Social_Media = ["Whatsapp", "Hike", "Facebook", "Whatsapp", "Telegram"]

Social_Media.take away("Whatsapp")

print (Social_Media)

The end result is as follows:

['Hike', 'Facebook', 'Whatsapp', 'Telegram']

Errors upon eradicating invalid gadgets

List = [1,2, "Linux", "Java", 25, 4, 9]

List.take away("PHP")

print (List)

The end result is as follows:

Traceback (most up-to-date name last):
File "C:PythonPython35test.py", line 3, in <module>
List.take away("PHP")
ValueError: listing.take away(x): x not in listing
