如何在 Python 的嵌套循环函数中限制循环的迭代次数？

代码：

friends= ['Ali', 'Asma','Amna', 'Izma', 'Omer','Zahid','Bilal','Sarah']
for vowelnames in friends:
    if vowelnames in ('Ali','Asma','Izma','Omer'):
        print('Oh my lovely friend ' + vowelnames + '! ,I would like you to come on my graduation ceremony')
    else:
        for cons in friends[:8]:
            if cons in ('Bilal','Sarah','Zahid'):
                print( cons + " I would like you to come on my graduation ceremony")

Answer 1

你必须使用“范围”

friends= ['Ali', 'Asma','Amna', 'Izma', 'Omer','Zahid','Bilal','Sarah']
for i in range(x): #Here instead of x you can give a number so that the loop will run 
                   #till that number
    for vowelnames in friends:
        if vowelnames in ('Ali','Asma','Izma','Omer'):
            print('Oh my lovely friend ' + vowelnames + '! ,I would like you to come 
                  on my graduation ceremony')
else:
    for cons in friends[:8]:
        if cons in ('Bilal','Sarah','Zahid'):
            print( cons + " I would like you to come on my graduation ceremony")

            print('Oh my lovely friend ' + vowelnames + '! ,I would like you to come 
                  on my graduation ceremony')
else:
    for cons in friends[:8]:
        if cons in ('Bilal','Sarah','Zahid'):
            print( cons + " I would like you to come on my graduation ceremony")

这是正确的答案-肯定是！
