问题描述
我的程序应该可以玩游戏.这是我遇到问题的加载屏幕.当我运行它时，time.sleep 就好像它在睡眠 0.1 秒，而不是我输入的小得多的数字.为什么是这样?有什么办法可以缩短延迟吗?代码如下:
导入操作系统随机导入导入时间导入系统def mywrite(line2,line1,t,s,x='small'):如果 x=='小':x=0.00000000000000000000000000000000000000000000000000000000000000000000001别的:x=random.random()*t+s字=''对于第 1 行中的 c:如果 line1.index(c)<len(line1)-1:打印(第2行)字=字+c打印(字)时间.sleep(x)os.system('cls')别的:打印(第2行)字=字+c打印(字，'\n')时间.sleep(x)mywrite('__________________________________________________________\n',' %33s'%'Scrambled',0.005,0.1,'random')print('按a"播放%30s'%'按s"退出')打印('__________________________________________________________')开始=输入()如果开始=='a':权限=1如果开始==':权限=0如果权限==0:系统退出()如果权限==1:print("选择难度")打印('简单-按一个')打印('硬压 b')print('Insane -Press c')差异=输入()y=0而权限==1:os.system('cls')我的写('''_ _ _(_) ___ __ _ __||||_ __ __ _||/_ \\/_` |/_` ||||'_ \\/_` ||||(_) ||(_| | | (_| | | | | | | | (_| ||_|\\___/\\__, |\\__,_||_||_||_|\\__,_||___/''', 0.005, 0.001)时间.sleep(2)os.system('cls')我的写('''_ _(_) _ _ ||_ _||/_` |||/_` ||||(_| | | | | (_| ||_|\__, ||_|\__,_||___/____ __||_ __/_ \/_` ||'_ \|(_) ||(_| | | | | |\___/\__,_||_||_|''', 0.005, 0.001)时间.sleep(2)os.system('cls')我的写('''_ _||__ _ (_) __ _||/_` |||/_` ||||(_| | | | | (_| ||_|\__,_||_|\__, ||___/____ __||_ __/_ \/_` ||'_ \|(_) ||(_| | | | | |\___/\__,_||_||_|''', 0.005, 0.001)时间.sleep(2)os.system('cls')我的写('''_ _ _||___ __ _ __||(_) _ __ __ _||/_ \/_` |/_` ||||'_ \/_` ||||(_) ||(_| | | (_| | | | | | | | (_| ||_|\___/\__,_|\__,_||_||_||_|\__, ||___/''', 0.005, 0.001)时间.sleep(4)os.system('cls')如果y==2:休息如果太长，这里是包含问题的部分:

解决方案
您可以通过执行以下操作来测试 time.sleep 的最小分辨率:
from datetime import datetime导入时间def test_time(延迟):开始 = datetime.now()时间.睡眠(延迟)完成 = datetime.now()差异 = 完成 - 开始返回 diff.total_seconds()在你的 REPL(空闲或终端或你使用的任何东西)中定义它并测试它.在我的系统上，使用 Python 3.6.1，我得到:
<预><代码>>>>测试时间(1)1.014032>>>测试时间(1)1.014032>>>测试时间(0.1)0.109204>>>测试时间(0.0001)0.015601>>>测试时间(0.0002)0.015601>>>测试时间(0.0000000000001)0.0156>>>测试时间(0.0000000000001)0.0156>>>测试时间(0.0000000000000000000000001)0.015601>>>所以 time.sleep 的最小分辨率在我的机器上大约是 0.0156 秒.您的个人实施可能会有所不同.
My programs supposed to play a game. It's the loading screen I'm having problems with. When I run it, time.sleep acts as if it's sleeping 0.1 seconds, instead of the much smaller numbers I input into it. Why is this? Is there a way I can make the delays shorter? Here's the code:
import os
import random
import time
import sys
def mywrite(line2,line1,t,s,x='small'):
if x=='small':
x=0.0000000000000000000000000000000000000000000000000000000000000000000000001
else:
x=random.random()*t+s
word=''
for c in line1:
if line1.index(c)<len(line1)-1:
print(line2)
word=word+c
print(word)
time.sleep(x)
os.system('cls')
else:
print(line2)
word=word+c
print(word,' \n')
time.sleep(x)
mywrite('__________________________________________________________\n',' %33s'%'Scrambled',0.005,0.1,'random')
print(' Press "a" to play %30s'%'Press "s" to exit')
print('__________________________________________________________')
start=input()
if start=='a':
permission=1
if start=='s':
permission=0
if permission==0:
sys.exit()
if permission==1:
print("Choose Difficulty")
print('Easy -Press a')
print('Hard -Press b')
print('Insane -Press c')
diff=input()
y=0
while permission==1:
os.system('cls')
mywrite('''

If that's too long, here's the part that contains the problem:

for c in line1:
if line1.index(c)<len(line1)-1:
print(line2)
word=word+c
print(word)
time.sleep(x)
os.system('cls')
else:
print(line2)
word=word+c
print(word,' \n')
time.sleep(x)
while permission==1:

BTW I'm only a few days into python, so please keep the explanations simple. Thank you.
解决方案
You can test minimum resolution of time.sleep by doing something like:
from datetime import datetime
import time
def test_time(delay):
start = datetime.now()
time.sleep(delay)
finish = datetime.now()
diff = finish - start
return diff.total_seconds()
Define that in your REPL (IDLE or terminal or whatever you use) and test it out. On my system, using Python 3.6.1, I get:
>>> test_time(1)
1.014032
>>> test_time(1)
1.014032
>>> test_time(0.1)
0.109204
>>> test_time(0.0001)
0.015601
>>> test_time(0.0002)
0.015601
>>> test_time(0.000000000001)
0.0156
>>> test_time(0.000000000001)
0.0156
>>> test_time(0.0000000000000000000000001)
0.015601
>>>
So the minimum resolution of time.sleep is somewhere around 0.0156 seconds on my machine. Your individual implementation may vary.
