Replaces print statement with built in function

[moriarty]

The print statement was removed with Python3, this change should work
for both Python2 and Python3.

The print(i),(ax) looks a little strange though.

I just ran an out-of-the-box sonar analysis on the project and found this: it wasn't actually causing me any issue.

After:

(note- ignore the unresolved in the "after" photo... the other project I have in sonar is the PointCloudLibrary)

I tried print(i, ax) and it gave me a different output

[moriarty]

test = { "hello", "world"}

for i, st in enumerate(test):
    print i, st

for i, st in enumerate(test):
    print(i, st)

for i, st in enumerate(test):
    print(i),(st)

[moriarty]

It's possible my test was wrong.

print(i),(ax) is a tuple of whatever is returned by print(i) (spoiler: None) and ax:

>>> print(1),(2)
1
(None, 2)

I've pushed a new commit with print(i, ax)

Strange, on my MacBook I get a different result, but it's also a different version of Python than on my server.

[ddemidov]

You are using print(...) version on python2 here, which (I guess) prints the tuple (i, st). The brackets are part of tuple in the second example.

>>> print('{} {}'.format(1, 2)) should give same results both for python2 and python3, but we don't support python2 anyway, so I don't see why would we want to be backward compatible.

[moriarty]

yes that print('{} {}'.format(1, 2)) doesn't look nice 😄
