All you have to do to combine them is c = a|b.
要将它们组合起来，您所要做的就是c = a|b.
Sets are unordered sequences of unique values. a|bis the unionof the two sets (a new set with all values found in either set). This is a class of operation called a "set operation", which sets provide convenient tools for.
集合是唯一值的无序序列。 a|b是union两个集合（一个新集合，其中包含在任一集合中找到的所有值）。这是一类称为“集合操作”的操作，它为集合提供了方便的工具。

You can use update() to combine set(b) into set(a) Try to this.
您可以使用 update() 将 set(b) 合并为 set(a) 试试这个。
a = {'a', 'b', 'c'}
b = {'d', 'e', 'f'}
a.update(b)
print a
and second solution is:
第二个解决方案是：
c = a.copy()
c.update(b)
print c
