Picamera图片命名

Question

我对picamera和python有点问题。我所要做的就是取一个变量名，然后用这个变量名和.jpg文件类型连接起来保存一张图片。

import picamera
import time


camera = picamera.PiCamera()

camera.vflip = True
camera.hflip = True
itemname = raw_input ('what is the item name? ')
time.sleep(6)
camera.capture(itemname,'.jpg')
time.sleep(2)
camera.close()
print "done"

Answer 1

这是正确的语法

import picamera
import time


camera = picamera.PiCamera()

camera.vflip = True
camera.hflip = True
itemname = raw_input ('what is the item name? ')
time.sleep(6)
camera.capture(itemname + ".jpg")
time.sleep(2)
camera.close()
print "done"
