Python 到达计数器时如何停止打印列表中的项目

我尝试运行一个循环，在列表中打印歌词行，然后在达到可变限制量时停止。虽然我用两种不同的方法尝试过，但都不正确

给我的问题是：

lyrics = ["I wanna be your endgame", "I wanna be your first string",
          "I wanna be your A-Team", "I wanna be your endgame, endgame"]
lines_of_sanity = 6

#You may modify the lines of code above, but don't move them!
#When you Submit your code, we'll change these lines to
#assign different values to the variables.

#Recall the Earworm problem (3.3.5 Coding Exercise 2). The
#first time, you would still finish printing the entire list
#of lyrics after lines_of_sanity was exceeded.
#
#Revise that code so that you always stop when lines_of_sanity
#is reached. If lines_of_sanity is 6, you would print 6 lines,
#no matter how many lines are in the list. If there are fewer
#than 6 lines in the list, then you'd repeat the list until
#the number of lines is reached.
#
#For example, with the values above, you'd print:
#I wanna be your endgame
#I wanna be your first string
#I wanna be your A-Team
#I wanna be your endgame, endgame
#I wanna be your endgame
#I wanna be your first string
#MAKE IT STOP
#
#That's 6 lines: the entire list once, then the first two lines
#again to reach 6. As before, print MAKE IT STOP when you're
#done.
#
#HINT: There are multiple ways to do this: some involve a small
#change to our earlier answer, others involve a more wholesale
#rewrite. If you're stuck on one, try to think of a totally
#different way!


#Add your code here! Using the initial inputs from above, this
#should print 7 lines: all 4 lines of the list, then the first
#two lines again, then MAKE IT STOP

我的答案及其产生的结果：

counter = 0
while counter <= lines_of_sanity:
    for item in (lyrics):
        print(item)
        counter += len(lyrics)
print("MAKE IT STOP")

计数器=0
而计数器编辑：进一步思考后简化了我的答案-这是使用模运算符
%
解决的一个好问题。模运算符的作用是在第一个操作数除以第二个操作数后返回余数。虽然不明显，但模运算符非常适合在列表上循环索引

例如：

lyrics = ["I wanna be your endgame", "I wanna be your first string", 
          "I wanna be your A-Team", "I wanna be your endgame, endgame"]

lines_of_sanity = 6

for i in range(lines_of_sanity):
    print(lyrics[i % len(lyrics)])
        
print("MAKE IT STOP")

输出：

I wanna be your endgame
I wanna be your first string
I wanna be your A-Team
I wanna be your endgame, endgame
I wanna be your endgame
I wanna be your first string
MAKE IT STOP

谢谢你的回答！虽然这对当前的歌词有效，但当代码与其他歌词进行测试时，例如：我们用歌词=[“我不能自己做这一切，不，我知道”，“我不是超人”]，第12行。我们希望您的代码打印以下内容：Indexer Ror:list index超出范围一切对我都有效，可能是变量不匹配？
lyrics = ["I wanna be your endgame", "I wanna be your first string", 
          "I wanna be your A-Team", "I wanna be your endgame, endgame"]

lines_of_sanity = 6

for i in range(lines_of_sanity):
    print(lyrics[i % len(lyrics)])
        
print("MAKE IT STOP")

I wanna be your endgame
I wanna be your first string
I wanna be your A-Team
I wanna be your endgame, endgame
I wanna be your endgame
I wanna be your first string
MAKE IT STOP
