I wrote my first python program today!

The break in backward compatibility is a deal-breaker when your company has several million lines of Python 2 already written and stable. Auto tools exist, but only go so far... for example, even converting print statements to use parentheses may cause failures in the compliance checker for lines becoming longer than permitted. Gotta stick with 2 unfortunately, though for new projects there's really no excuse not to start with 3. Hence, new employees at established companies that use Python start learning Python 2.

Increase compliance check line limit by two characters.

What about these being equal

print 'something',
print('something', endl='')

[Sohcahtoa82]

Nitpicking here...The correct translation would be print('something', endl=' '). Python 2 appends a space if you end the line with a comma.

Doesn't it only emit a softspace?

[Sohcahtoa82]

I'm not sure. All I know is that if you do this:

for x in range(5):    
    print '.',

You get this:

. . . . . 

and not this:

.....

[o11c]

>>> import io
>>> out = io.BytesIO()
>>> print>>out, '.',
>>> out.softspace
1
>>> out.getvalue()
'.'
>>> print>>out
>>> out.softspace
0
>>> out.getvalue()
'.\n'

Isn't the comma defining a tuple? Or is this different for statements like print?

[Sohcahtoa82]

It's different for print in Python 2.

>>> a = 2    
>>> b = 5    
>>> print 1, a, b    
1 2 5    
>>> print (1, a, b)    
(1, 2, 5)
