更新说明： - Added sort, shuffle, and join functions- Added syntax for selecting several elements from a list. If L is a list, L[1,3,5] selects three elements from the list, L[3...5] selects the third through fifth elements of the list, and L[3...] selects the third though final elements of the list. If M is a list, L[M] selects the elements of L with indices given by the elements of M.- Added syntax for filtering lists. If L is a list, L[L>0] selects the positive elements of the list.
