我的输出是 5005 个序列号，但我只想要 100 个。目前它将 5005 个序列号写入一个文件，我希望它写入 100 个序列号。这个程序将用于生成序列号，以便在另一个脚本中进行最安全的登录，请帮助:)

让我们简化您的程序以了解如何获得 5005 个结果：

gencodelist = []
for i in range(1, 100):
  gencodelist.append(str(i) + ' ')
  gencodeout = ''.join(gencodelist)
  print(gencodeout)

这里我们向列表中添加元素gencodelist99 次（从 1 到 99），并且每次都打印该列表的所有元素。因此，我们1 + 2 + ... + 99在输出中有数字（实际上是 4950，而不是您的数字 5005）。

gencodelist所以，问题很简单：你在函数的一开始就不清楚gencode()。
