[英]Construct a list of integers from bigger to smaller in python
我正在尝试开发一个小鼠标控制器应用程序。 它应该得到(X,Y)坐标并使光标移动到那里。
问题是当它尝试进入小于当前坐标的X坐标时。
import win32con
from win32api import GetCursorPos, SetCursorPos, mouse_event, GetSystemMetrics
from time import sleep
def clickWithCursor(xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
def goAhead(x, y):
for x in range(min(xCurrent, xDesired), max(xDesired, xCurrent), 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
mouse_event(win32con.MOUSEEVENTF_LEFTDOWN,x,y,0,0)
mouse_event(win32con.MOUSEEVENTF_LEFTUP,x,y,0,0)
return goAhead(0, 0)
def main():
clickWithCursor(243, 184)
main()
以上只是一个非常糟糕的尝试,这不会给我我想要的结果。 我一直在寻找如何做到这一点,只是找不到正确的方法。
简而言之,我想构建一个列表,根据参数符号顺序,它将从逻辑上从大到小,或从更小到更大。
所以,如果我给出我希望得到的范围(4,1):[4,3,2]或范围(1,4),它就不会介意并以正确的方式构建它......
编辑:我根据答案重构了代码,并让其他用户更容易阅读。 注意MouseController类中的“sequence”方法:
from win32con import MOUSEEVENTF_LEFTDOWN, MOUSEEVENTF_LEFTUP
from win32api import GetCursorPos, SetCursorPos, mouse_event
from time import sleep
class CursorPositionPrinter(object):
"""docstring for CursorPositionPrinter"""
def print_cursor_pos(self):
print GetCursorPos()
def __init__(self):
super(CursorPositionPrinter, self).__init__()
class AutoClicker(object):
"""docstring for AutoClicker"""
def click(self, times):
xCurrent, yCurrent = GetCursorPos()
for i in xrange(times):
self.simple_click(xCurrent, yCurrent)
def simple_click(self, x, y):
mouse_event(MOUSEEVENTF_LEFTDOWN, x, y, 0, 0)
mouse_event(MOUSEEVENTF_LEFTUP, x, y, 0, 0)
def __init__(self):
super(AutoClicker, self).__init__()
class MouseController(CursorPositionPrinter, AutoClicker):
"""docstring for MouseController
Controlls your mouse magically!!!"""
def sequence(self, a, b, n):
mn, mx = a, b
step = -n if mn > mx else n
for value in xrange(mn, mx, step):
yield value
def click_with_cursor(self, xDesired, yDesired):
self.go_to_coordinates(xDesired, yDesired)
self.simple_click(xDesired, yDesired)
def go_to_coordinates(self, xDesired, yDesired):
xCurrent, yCurrent = GetCursorPos()
slope = float(yDesired - yCurrent) / float(xDesired - xCurrent)
for x in self.sequence(xCurrent, xDesired, 2):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(self.latency)
SetCursorPos((xDesired, yDesired))
def __init__(self, latency=0.02):
super(MouseController, self).__init__()
self.latency = latency
获得最小值和最大值后,取决于哪个值更大,取得-1或1的步长:
def up_down(a, b):
mn, mx = min(a), max(b)
step = -1 if mn > mx else 1
return range(mn, mx, step)
输出:
In [9]: list(up_down([4,5,5,7],[0,1]))
Out[9]: [4, 3, 2]
In [10]: list(up_down([0,1],[4,5,5,7] ))
Out[10]: [0, 1, 2, 3, 4, 5, 6]
如果min更大,我们需要一个消极的步骤,如果不是只使用1的步骤。
为了更明显地如何在您自己的代码中使用逻辑,您只需使用if / else:
def goAhead(x, y,n=1):
step = -n if xCurrent > xDesired else n
for x in range(xCurrent, xDesired, step):
y = int(slope * (x - xCurrent) + yCurrent)
SetCursorPos((int(x), y))
sleep(0.002)
如果你想改变的步长,你可以通过任何n
你想
lim1, lim2 = 10, 2
step = 1 if lim1<lim2 else -1
lst = list(range(lim1, lim2, step))
print(lst)
=> [10,9,8,7,6,5,4,3]
有:
lim1,lim2 = 2,10
=> [2,3,4,5,6,7,8,9]
此表格允许:
列表(范围(lim1,lim2,1如果lim1
range(a, b, -1 if a > b else 1)
