2. Accessing

3. delete

len(list) #Gives the total length of the list.

max(list) #Returns item from the list with max value.

list.append(obj) #Appends object obj to list

list.count(obj) #Returns count of how many times obj occurs in list

list.extend(seq) #Appends the contents of seq to list

list.index(obj) #Returns the lowest index in list that obj appears

list.insert(index, obj) #Inserts object obj into list at offset index

list.pop(obj=list[-1]) #Removes and returns last object or obj from list

list.remove(obj) #Removes object obj from list

list.reverse() #Reverses objects of list in place
