我如何让这个 for 循环每 8 次开始一个新行：

当前： https : //i.stack.imgur.com/kyJyb.png需要： https : //i.stack.imgur.com/SLN8B.png

def generate_votes(candidates):
    votes = 0
    for i in candidates:
        votes += 1   
    votes *= 10
    print("\nGenerating ",votes," votes between 0 and ", (votes // 10)-1)
    
    for i in range(votes//10):
        for i in range(0,8):
            n = random.randint(0,(votes//10)-1)
            print(n,end='\t')

这是一个简单的修复，

您的代码：

def generate_votes(candidates):
    votes = 0
    for i in candidates:
        votes += 1   
    votes *= 10
    print("\nGenerating ",votes," votes between 0 and ", (votes // 10)-1)
    
    for i in range(votes//10):
        for i in range(0,8):
            n = random.randint(0,(votes//10)-1)
            print(n,end='\t')

变成：

def generate_votes(candidates):
    votes = 0
    for i in candidates:
        votes += 1   
    votes *= 10
    print("\nGenerating ",votes," votes between 0 and ", (votes // 10)-1)
    
    for i in range(votes//10):
        for i in range(0,8):
         print('\n')
            n = random.randint(0,(votes//10)-1)
            print(n,end='\t')

我添加了print('\\n') ，这是一个 python 命令，它将直接在你的程序中开始一个新行。 我将它嵌套在for循环中，因此它只会在第 8 次迭代之后发生。
