  • Common list methods in Python
    Below are some list functions that are commonly required in order to complete Coderbyte challenges. You can view a longer list of Python list functions here.

    append and insert

    Add an element to the end of the list and add an element into a specific index in the list. li = [1, 2, 3] li.append(4) # [1, 2, 3, 4] li.insert(0, -100) # [-100, 1, 2, 3, 4]

    pop and remove

    Remove the last element from the list or remove a specific element from the list. li = [1, 2, 3, 4] li.pop # 4 print li # [1, 2, 3] li.remove(2) print li # [1, 3]

    index

    Return the index of the specific element. li = [1, 2, 3, 4] print li.index(3) # 2

    reverse

    Reverse the list. li = [1, 2, 3, 4] li.reverse() print li # [4, 3, 2, 1]

    count

    Count how many times an element appears in the list. li = [1, 2, 3, 4, 1, 1, 2] print li.count(1) # 3
