Python 'unexpected EOF while parsing' eclipse pydev run selected code

Question

If I select the following code and click "Run selected Code" in eclipse, it will give me an error.

class abc(object):
    def __init__(self):
        print 'base'

    def run(self):
        print 'run'

Error message:

class abc(object):
    def __init__(self):
        print 'base'

    def run(self):
        print 'run'
  File "<ipython-input-22-8e1ec627fd90>", line 1
    def run(self):
                  ^
SyntaxError: unexpected EOF while parsing

run

However, if I remove the space between the two functions then it will run Ok(see below), is this a bug in pydev? Any way I can over come this issue?

class abc(object):
    def __init__(self):
        print 'base'    
    def run(self):
        print 'run'

I think what you're seeing is the result of using the interactive console to run your code (i.e.: http://www.pydev.org/manual_adv_interactive_console.html).

The issue is that when you send the code to the console through that action, it won't do any edit to your code, and when the console sees a line with 0-width, it'll conclude that the Python block is finished.

So, there are some workarounds for that:

1. Don't right-trim your blocks (i.e.: leave spaces to the block indent instead of a 0-width line).

2. If you don't want to run just a section of your code, deselect all the code and execute the whole file with Ctrl+Alt+Enter.

3. Deselect the code, go to the first line and send the contents to the console line-by-line with F2 (F2 will send the current line and will move the cursor to the next line with contents and may even fix the indents, so, it should be easy to select the block you want to send to the console).

4. Don't use the interactive console and do a plain run with F9 (although in this case as it'll launch in a new non-interactive console, the symbols won't be available for inspection afterwards).

5. If you work using TDD (test driven development), then run the test code with Ctrl+F9 (see http://www.pydev.org/manual_adv_pyunit.html for details) -- again, in this mode it won't be using the interactive console.
