python 遇到的问题

程序如下：
#Print magician and their name with 'the great' in front of them
magician = ['Diedle','kuler','Gargon']
changed_magician = []
def show_magicians(mag):
    print('The magician that will be presented are:')
    for magi in mag:
        print(magi.title())

def make_great(magic,magical):
    for magici in magic:
        magici = magic.pop(0)
        magici = "The Great " +magici
        magical.append(magici)


make_great(magician[:],changed_magician)
show_magicians(magician)
show_magicians(changed_magician)




大家帮个忙，这里show_magicians(changed_magician)工作不正常-只有第一个和第二个名子前加了The Great, 第三个名字没有显示，输出如下：
The magician that will be presented are:
Diedle
Kuler
Gargon
The magician that will be presented are:
The Great Diedle
The Great Kuler


我应该如何让第三个名字显示出来（前面加好了The Great)? 谢谢回答

#Print magician and their name with 'the great' in front of them
magician = ['Diedle','kuler','Gargon']
changed_magician = []
def show_magicians(mag):
    print('The magician that will be presented are:')
    for magi in mag:
        print(magi.title())

def make_great(magic,magical):
    for magici in magic:
        #magici = magic.pop(0)
        magici = "The Great " +magici
        magical.append(magici)


make_great(magician[:],changed_magician)
show_magicians(magician)
show_magicians(changed_magician)

   #magici = magic.pop(0) 这一行应该怎么改？
