Remove element from list:

The remove() method finds the first instance of the element (passed an argument) and removes it from the list. Let's consider the following examples:

• Example 1:

       >>> sequence = [1, 1, 2, 3, 4, 7, 5, 6, 7]
       >>> sequence.remove(7)
       >>> sequence
       [1, 1, 2, 3, 4, 5, 6, 7]

• Example 2:

       >>> sequence.remove(1)
       >>> sequence
       [1, 2, 3, 4, 5, 6, 7]

• Example 3:

       >>> sequence.remove(1)
       >>> sequence
       [2, 3, 4, 5, 6, 7]
