As the error message says, you are using non-ascii characters (the “ and ”) 
in your code.

But even if you were to read the linked document and would add the line

# -*- coding: utf-8 -*

at the beginning of your script you would run into the next SyntaxError.

You are trying to quote a string literal with

“...”

but Python only understands

"..."

or 

'...'

Change the os.system() call to

os.system("dcm2jpg.exe IM-0004-0004.dcm")

and your script should work.

An unrelated issue:

> exit

to call a function the () is required -- to end the script at an arbitrary 
point use

exit()

However, as execution also ends automatically when the last line of the 
script is reached it is better to remove the

> exit

line completely.
