How to take screenshot of the screen in Python?

Question

I would like to make a program that screenshots the screen ( screen photo) in Python.

I found the following code:

import pyscreenshot as ImageGrab

if __name__ == "__main__":
    # fullscreen
    im=ImageGrab.grab()
    im.show()

The code does nothing (apparently gets stuck)!

What does it mean: if __name__ == "__main__":?

First if you have not installed the module, install:

~$ sudo apt-get install python-pip && pip install pyscreenshot

_{Obs: The pip is a tool for installing Python modules.}

To use the pyscreenshot just do:

import pyscreenshot as ImageGrab

def main():
    imagem = ImageGrab.grab()
    imagem.save('screenShot1.jpg', 'jpeg')

if __name__ == "__main__":
    main()

The code above will generate an image JPEG and save her as screenShot1.jpg in the same directory as script.
