Getting SyntaxError for print with keyword argument end

Question

I have this python script where I need to run gdal retile py  but I get an exception on this line  if Verbose     print  quot Building internam Index for  d tile s      quot    len inputTiles   end       The end     is invalid syntax  I am curious as to why  and what the author probably meant to do  I m new to python if you haven t already guessed   I think the root cause of the problem is that these imports are failing and therefore one must contain this import from   future   import print function try      from osgeo import gdal    from osgeo import ogr    from osgeo import osr    from osgeo gdalconst import   except     import gdal    import ogr    import osr    from gdalconst import

How about this    Only for use in Python 2 6 0a2 and later from   future   import print function   This allows you to use the Python 3 0 style print function without having to hand-edit all occurrences of print

Even I was getting that same error today  And I ve experienced an interesting thing  If you re using python 3 x and still getting the error  it might be a reason      You have multiple python versions installed  on same drive  And when   you re presing the f5 button the python shell window  of ver   lt  3 x    pops up   I was getting same error today  and noticed that thing  Trust me  when I execute my code from proper shell window  of ver  3 x   I got satisfactory results

First of all  you re missing a quote at the beginning but this is probably a copy paste error   In Python 3 x  the end     part will place a space after the displayed string instead of a newline  To do the same thing in Python 2 x  you d put a comma at the end   print  Building internam Index for  d tile s         len inputTiles

Try this one if you are working with python 2 7   from   future   import print function

It looks like you re just missing an opening double-quote   Try   if Verbose     print  Building internam Index for  d tile s         len inputTiles   end

For python 2 7 I had the same issue  Just use  from   future   import print function  without quotes to resolve this issue This Ensures Python 2 6 and later Python 2 x can use Python 3 x print function

In python 2 7 here is how you do it   mantra    Always look on the bright side of life  for c in mantra  print c    output A l w a y s   l o o k   o n   t h e   b r i g h t   s i d e   o f   l i f e   In python 3 x  myjob   hacker  for c in myjob  print  c  end       output  h a c k e r

I think the author probably meant   if Verbose     print  Building internam Index for  d tile s         len inputTiles   end        He s missing an initial quote after print    Note that as of Python 3 0  print is a function as opposed to a statement  if you re using older versions of Python the equivalent would be   print  Building internam Index for  d tile s         len inputTiles    The end parameter means that the line gets     at the end rather than a newline character  The equivalent in earlier versions of Python is   print  Building internam Index for  d tile s         len inputTiles      thanks Ignacio

Are you sure you are using Python 3 x  The syntax isn t available in Python 2 x because print is still a statement   print  foo    bar  end        in Python 2 x is identical to  print   foo    bar  end        or  print  foo    bar  end       i e  as a call to print with a tuple as argument   That s obviously bad syntax  literals don t take keyword arguments   In Python 3 x print is an actual function  so it takes keyword arguments  too   The correct idiom in Python 2 x for end     is   print  foo    bar     note the final comma  this makes it end the line with a space rather than a linebreak   If you want more control over the output  consider using sys stdout directly  This won t do any special magic with the output   Of course in somewhat recent versions of Python 2 x  2 5 should have it  not sure about 2 4   you can use the   future   module to enable it in your script file   from   future   import print function   The same goes with unicode literals and some other nice things  with statement  for example   This won t work in really old versions  i e  created before the feature was introduced  of Python 2 x  though

This is just a version thing  Since Python 3 x the print is actually a function  so it now takes arguments like any normal function   The end     is just to say that you want a space after the end of the statement instead of a new line character  In Python 2 x you would have to do this by placing a comma at the end of the print statement   For example  when in a Python 3 x environment   while i lt 5      print i      i i 1   Will give the following output   0 1 2 3 4   Where as   while i lt 5      print i  end            i i 1   Will give as output   0 1 2 3 4
