Hi. Good day. I am new to Python but I have had experience with C/C++ and
Matlab. I've been reading How to Think Like a Computer Scientist and skimmed
Core Python to learn. Now I havent done the exercises because I wanted to
get down to the project I'm doing in my spare time. The project involves
taking pictures. I found a program called gphoto2 that can do what i need.
But it was in command line. And i wanted to access it with a program. So I
made a class that calls gphoto2 to control a camera. Here's the code.
class CamHandle(object):
def __init__(self):
import os
w = os.system('gphoto2 --auto-detect > CamHandleLog.txt')
test = os.system('gphoto2 --capture-image >> CamHandleLog.txt')
def captureImage(self):
import os
x = os.system('gphoto2 --capture-image >> CamHandleLog.txt')
def getAllImages(self):
import os
y = os.system('gphoto2 --get-all-files >> CamHandleLog.txt')
def deleteAllImages(self):
import os
z = os.system('gphoto2 -DR >> CamHandleLog.txt')
Now when I import the file to the interpreter and instantiate the class, it
works. Each function works. I havent done any error handling or exception
handling yet but it works for now. However, I am bothered with the import
statements in each function. Correct me if I am wrong but each "import os"
statement only exists in each method. Is there a way to only import the os
module once and use it in each method?
Thank you and have a nice day.
