数字打印机，随机整数不工作

Question

好的，所以我试图在repl.it上创建一个程序，它可以打印偶数、奇数、连续数或随机数。在这个程序中，你可以决定所需的时间、打印的数量以及(对于随机数(最高和最低数。

然而，每当我选择随机并尝试运行它时。这会弹出

File "main.py", line 76, in <module>
massprint()
File "main.py", line 24, in massprint
print(random.randint(int(randhighcap),int(randlowcap)),flush=True, end=" ")
File "/usr/lib/python3.8/random.py", line 248, in randint
return self.randrange(a, b+1)
File "/usr/lib/python3.8/random.py", line 226, in randrange
raise ValueError("empty range for randrange() (%d, %d, %d)" % (istart, istop, width))
ValueError: empty range for randrange() (100, 1, -99)

这是repl项目的链接，因此您可以查看代码。(或者代码在下面。(

As"Johnny Mopp"；说，

翻转参数，使较低的数字先出现：print(random.randint(int(randlowcap(，int(randhighcap((，flush=True，end="(。randint((返回一个随机整数N，使得<=N<=b.randrange(a，b+1(的别名。

说实话，真不敢相信我没有想到这一点。
