How do I remove a specific value from a list in Python?
Python List remove()In this tutorial, we will learn about the Python List remove() method with the help of examples. Show
The remove() method removes the first matching element (which is passed as an argument) from the list. Example# create a list prime_numbers = [2, 3, 5, 7, 9, 11]# remove 9 from the list
prime_numbers.remove(9)
# Updated prime_numbers List
print('Updated List: ', prime_numbers)
# Output: Updated List: [2, 3, 5, 7, 11]Why use Lists?Sometimes, there may be situations where you need to handle different types of data at the same time. For example, let’s say, you need to have a string type element, an integer and a floating-point number in the same collection. Now, this is fairly impossible with the default data types that are available in other programming languages like C & C++. In simple words, if you define an array of type integer, you can only store integers in it. This is where Python has an advantage. With its list collection data type, we can store elements of different data types as a single ordered collection! 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! How to remove an item from the List in Python?Python Lists have various in-built methods to remove items from the list. Apart from these, we can also use del statement to remove an element from the list by specifying a position. Let’s look at these methods – Method 1: Using del statement

Method 2: Using remove()

Remove an element from List by value using list.remove()Python’s list provides a member function to remove an element from list i.e. It removes the first occurrence of given element from the list. For example, Suppose we have a list of numbers i.e. Let’s remove 56 from the given list using list.remove() i.e. # Remove first occurrence of 56 from List listOfnum.remove(56) It will remove the first occurrence of 56 from the above lists. Lists contents will be now, [12, 44, 45, 34, 3, 56, 4, 33, 44, 56] If we try to remove the element that doesn’t exists in list then list.remove() will throw exception. Therefore before calling list.remove() we should either, Advertisements Check if element exists in list i.e. Or use try / except i.e. # If given element doesn't exists in list, then remove() can throw Error # Therefore use try / except while calling list.remove() try : listOfnum.remove(99) except ValueError: print("Given Element Not Found in List") Related Articles
