Many set methods can also be written using operators. If acids and bases are two sets, for example, then acids | bases creates a new set containing their union (that is, all the elements from both acids and bases), while acids <= bases tests whether all the values in acids are also in bases. All the operators that sets support are listed in Table 12, ​Set operators​.
