append(value)

S.append(value) – append value to the end of the sequence

clear() → None – remove all items from S

count(value) → integer – return number of occurrences of value

current()

Gets the current object at the top of the stack (i.e. index [-1] :returns: :rtype: Object at the last position

S.extend(iterable) – extend sequence by appending elements from the iterable

get_metadata()

index(value[, start[, stop]]) → integer – return first index of value.

Raises ValueError if the value is not present.

Supporting start and stop arguments is optional, but recommended.

insert(key, value)

pop([index]) → item – remove and return item at index (default last).

Raise IndexError if list is empty or index is out of range.

remove(value)

S.remove(value) – remove first occurrence of value. Raise ValueError if the value is not present.

reverse()

S.reverse() – reverse IN PLACE

Return type

None
