Question

我的输出是5005序列号，但我只想要100。目前它将5005个序列号写入一个文件，我希望它能够写出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大多数安全登录请帮助：）

让我们简化您的程序，以了解如何获得5005结果：

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

这里我们将列表gencodelist中的元素添加99次（从1到99），并且每次都打印此列表的所有元素。所以，我们在输出中有1 + 2 + ... + 99个数字（事实上它是4950，而不是你的数字5005）。

所以，问题很简单：你没有在函数gencodelist的最开头清除gencode()。

我的Python for循环执行5005次，但它意味着执行100次
