This is a small platform-independent python script to take a screenshot of the entire screen. The code is in Python 2.7 and requires the wxPython library which is available in all platforms. By default, it takes an instant screenshot of the screen and saves it as screenshot.png in the same folder as the script. Two command line arguments can be passed as:
python sshot.py <delay in seconds> <filename to save in>
Delay delays the screenshot by the designated seconds so that you can arrange the screen or windows as required.
The filename argument will save the screenshot in the file <filename>.png . Note that the png suffix is assigned automatically.
