python - 生成随机 float

Question

现在我正在努力让 Python 在您的屏幕上“打字”(我感到无聊和实验)，我靠自己走到了这一步，但我找不到任何在我的脚本中使用小数的方法，因为 Python 只接受 randint() 的整数。

#include <stdio.h>;
import sys;
import time;
import os;
import random;
os.system("clear");

script = "I just really need to type something right now. I'm not sure why, but I really feel like typing on the Chromebook right now. It seems kinda weird, but I like doing this. It helps me practice what I'm doing. I've noticed that I'm a lot worse at typing lately, and I don't know why. Maybe it's because I've been working with a chunky keyboard, and these Chromebook keyboards are extremely thin. Yup, this is actually entertaining for me. I'm not exactly sure why I want to do this, but I just do. It's almost addicting to me, and I don't know why.\n";

for i in range(0, 587):
sys.stdout.write(str(scripti));
sys.stdout.flush();
time_num = random.randint(0.1, 0.4);
time.sleep(time_num);

我得到的输出是:

ITraceback (most recent call last):
File "main.py", line 11, in <module>
time_num = random.randint(0.1, 0.4);
File "/usr/lib64/python2.7/random.py", line 242, in randint
return self.randrange(a, b+1)
File "/usr/lib64/python2.7/random.py", line 187, in randrange
raise ValueError, "non-integer arg 1 for randrange()"
ValueError: non-integer arg 1 for randrange()

有什么想法吗？

编辑:不要告诉我如何简化它，因为这只是为了学习。

为什么不使用随机均匀分布呢？在这种情况下，您可以获得非整数数值。使用:

import random
random.uniform(0.1,0.4)
