试图理解这个问题。首先让我们通过以下方式使该代码能够实际运行：
import pywinauto
import time
import sys
htmlpres = "zcuba.dk/2014"
chrome = "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"
class Presentation:
def __init__(self):
pass
def start(self):
app = pywinauto.application.Application()
app.start_(chrome)
pwa_app = pywinauto.application.Application()
while True:
try:
w_handle = pywinauto.findwindows.find_windows(class_name='Chrome_WidgetWin_1')[0]
window = pwa_app.window_(handle=w_handle)
window.TypeKeys(htmlpres, with_spaces = True)
window.TypeKeys("~")
window.TypeKeys("{F11}")
break;
except:
e = sys.exc_info()[0]
print e
time.sleep(1)
p = Presentation()
p.start()
现在它在这里工作，我找不到任何错误......对不起
代码的下一个调试版本，它看起来不像您的原始版本，并且有很多输出可以帮助您查明您的问题！
