Method	Description

`list.pop(~)`	removes the element at the given index from a list and then returns the removed value
`list.remove(~)`	removes the first occurrence of the element with the specified value

del statement

The del statement is a simple way to remove an item at a particular position in the list:


        
        
            
                
                
                    vegetables = ['potato', 'carrot', 'cabbage']
del vegetables[2]
print(vegetables)
                
            
            ['potato', 'carrot']

Pop method

The list.pop(~) method allows you to use the value of an item after you remove it from the list:


        
        
            
                
                
                    fav_animals = ['cat','doge','bird']
norm_animals = []

# Pop last element of fav_animals and append it to norm_animals
norm_animals.append(fav_animals.pop())

print("fav_animals =", fav_animals)
print("norm_animals =", norm_animals)
                
            
            fav_animals = ['cat', 'doge']
norm_animals = ['bird']

At fav_animals.pop() we remove 'bird' from list fav_animals and return it. Then we use this return value as an input to norm_animals.append(~) and 'bird' is added to the norm_animals list.

Remove method

The list.remove(~) method allows you to remove an element from a list based on its value. This is useful when you do not know the position of the element on the list:


        
        
            
                
                
                    numbers = [1, 2, 2, 3, 4]

# Remove first occurrence of 2 from numbers
numbers.remove(2)

print(numbers)
                
            
            [1, 2, 3, 4]

WARNING

The remove method only deletes the first occurrence of the value in the list. To remove all occurrences you would need to use a for loop.
