Python regular collection of camera image upload FTP server function

The first is a screenshot, which captures an image from the camera:

while 1:   # Test the existence of the camera 
    try:
        cam = Device()
    except:
        print "no webcam found!"
        continue
    break

Then upload the image to the FTP server:

remote = ftplib.FTP('127.0.0.1') # Login server 
remote.login()
file = open('%s.jpg'%cur_time,'rb')   # Name the picture by time 
remote.storbinary('STOR %s.jpg'%cur_time,file) # To upload pictures 
file.close()

Of course, delete the image at the end
Here's how to upload pictures from the camera to the local FTP every second:

<span style="font-family:  Song typeface , Arial; line-height: 15px; background-color: rgb(245, 247, 248); ">    </span><pre name="code" class="python">remote = ftplib.FTP('219.246.57.162')
remote.login()
while 1:
    try:
        remote.nlst("1.txt")
    except:
        print "not ready to start!"
        continue
    timex = time.localtime()
    cur_time = "%4d%02d%02d%02d%02d%02d"%(timex[0],timex[1],timex[2],timex[3],timex[4],timex[5])
    cam.saveSnapshot('%s.jpg'%cur_time)  
    #remote.dir()
    file = open('%s.jpg'%cur_time,'rb')
    remote.storbinary('STOR %s.jpg'%cur_time,file)
    file.close()
    os.system("del %s.jpg"%cur_time)
    #print "upload ok!"
    time.sleep(1)
remote.quit()</pre><br>
