Question

这是我的代码：

series = 0

for counter in range (1, 30):
    if counter > 1:
        for i in range (2, counter):
            if (counter % i) == 0:
                series += 1
                break
        else:
            print ("The longest series of composite numbers under 10.000 starts at %d and ends at %d the series is %d long" % ((counter-series), counter, series))
            series = 0

我希望它只给出最长的序列，我想我需要将变量序列存储在某个地方，并检查每次迭代，如果序列的新值比先前的值高，然后交换，如果序列的值更高，并且然后只打印一次。但是我不知道如何有效地存储和交换。

希望这很清楚

我使用了for else循环，它起作用了，这是我的最终代码：

series = 0
b = 0 
a = 0

for num in range (1, 10000):
    for j in range (2, num):
        if (num % j) == 0:
            series += 1
            break 

    else:
        if series > b:
            b = series
            a = num 
            series = 0
        else: 
            series = 0
print ("De langste reeks niet-priemgetallen onder de 10.000 begint op %d en eindigt op %d" % (((a-b), a-1)))   
print ("de reeks is %d lang" % b)

如何找到10000以下的最长复合数字序列？如何只打印最长的系列？
