同时运行更多循环? [英] Run more loops at the same time?
本文介绍了同时运行更多循环?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
首先，我必须说我是Python的初学者.这些是我创建课程的第一步.现在是我的问题.在那张图片上，我介绍了我的代码应该起作用.
- 启动程序(运行)
- 检查应打开哪些仪器.有三种 可能性，您可以在一个，两个或三个单元上供电 同时. (电源#A/B/C)
- 此外，每增加一个功率单元，您都可以打开 温度传感器(温度#A，B，C)
- 取决于涉及哪个单元来运行循环#A，#B，#C或 例如两个单元#B，#C或全部三个.这实际上是我的问题.怎么也能同时 同时运行两个或什至三个循环?
希望您能给我一些建议和帮助，以解决我的问题.
下面，我将放置我的代码，以便您可以参考并注意我可能会更改或改进的代码.

解决方案
一个可怕的简化示例，说明如何使用(和切换)并行运行的三个不同循环(在这种情况下)打印三个不同的单词.
使用Tkinters的after()方法，这些循环可以在主循环内部中运行:
from Tkinter import *
class MultiLoop:
def __init__(self):
self.master = Tk()
self.run1 = False
self.run2 = False
self.run3 = False
button1 = Button(text="Toggle Monkey", command = self.togglemonkey).pack()
button2 = Button(text="Toggle eats", command = self.toggleeats).pack()
button3 = Button(text="Toggle banana", command = self.togglebanana).pack()
# first call:
self.master.after(0, self.loop1)
self.master.after(0, self.loop2)
self.master.after(0, self.loop3)
self.master.mainloop()
# The three loops
def loop1(self):
if self.run1 == True:
print("Monkey")
else:
pass
# schedule next run
self.master.after(100, self.loop1)
def loop2(self):
if self.run2 == True:
print("eats")
else:
pass
# schedule next run
self.master.after(1000, self.loop2)
def loop3(self):
if self.run3 == True:
print("banana")
else:
pass
# schedule next run
self.master.after(2000, self.loop3)
# The toggle functions
def togglemonkey(self):
self.run1 = True if self.run1 == False else False
def toggleeats(self):
self.run2 = True if self.run2 == False else False
def togglebanana(self):
self.run3 = True if self.run3 == False else False
MultiLoop()
First of all, I have to say that I'm a beginner in Python. These are my first steps in creating a class. And now my question.On that picture, I presented what my code should work.
- Start the program (Run)
- Check what instruments should be power on. There are three possibilities and you can power one, two or all three Units at the same time. (Power #A/B/C)
- Furthermore, with each power unit additional you can turn on Temperatur sensor (Temp. #A,B,C)
- Depending on which units are involved to run a Loop #A, #B, #C or for example two units #B,#C or perhaps all three.This is actually my Problem and question. How can be able to simultaneously also at the same time, run two or maybe even three loops ?
I hope you can give me some advice and help in solving my problem.
Below I will put my code so you can refer and pay Attention what I could change or improve in my code.

A terrifyingly simplified example of how you can use (and toggle) three different loops, running in parallel, (in this case) printing three different words.
Using Tkinters's after() method, these loops can run inside the main loop:
from Tkinter import *
class MultiLoop:
def __init__(self):
self.master = Tk()
self.run1 = False
self.run2 = False
self.run3 = False
button1 = Button(text="Toggle Monkey", command = self.togglemonkey).pack()
button2 = Button(text="Toggle eats", command = self.toggleeats).pack()
button3 = Button(text="Toggle banana", command = self.togglebanana).pack()
# first call:
self.master.after(0, self.loop1)
self.master.after(0, self.loop2)
self.master.after(0, self.loop3)
self.master.mainloop()
# The three loops
def loop1(self):
if self.run1 == True:
print("Monkey")
else:
pass
# schedule next run
self.master.after(100, self.loop1)
def loop2(self):
if self.run2 == True:
print("eats")
else:
pass
# schedule next run
self.master.after(1000, self.loop2)
def loop3(self):
if self.run3 == True:
print("banana")
else:
pass
# schedule next run
self.master.after(2000, self.loop3)
# The toggle functions
def togglemonkey(self):
self.run1 = True if self.run1 == False else False
def toggleeats(self):
self.run2 = True if self.run2 == False else False
def togglebanana(self):
self.run3 = True if self.run3 == False else False
MultiLoop()
