如何用函数修改一个列表的元素？

问题是这样的

我要定义了两个函数
第一个函数是这样的：

这个函数是用来打印列表的元素
def show_magicians(names):
for magician_name in names:
print(magician_name)

如何定义第二个函数把下面的列表中的每一个元素都加上“the Great" 字样，然后由上面的函数打印出来。
最终结果是：
The Great Jack
The Great Tom
The Great Jon

magician_names = ['Jack', 'Tom', 'Jon']

求大神指教，谢谢

def show_magicians(names):
for magician_name in names:
      print(magician_name)

def change_magicians(names):
for i in range(len(names)):
      names[i] = 'The Great ' + names[i]

magician_names =  ['Jack', 'Tom', 'Jon']
change_magicians(magician_names)
show_magicians(magician_names)
