# "from __future__ import print_function" fails on Sage scripts

Hello, Sage Community.

I am trying to use the "print" function in a .sage script, so I have added the line

```
from __future__ import print_function
```

as the first line to be included in my .sage file. Unfortunately, when running `sage test.sage`

, Sage preparses the document and creates an auxiliary file "test.sage.py", which makes an import, then predefines some constants, and finally adds my preparsed code. As a consequence, the `from __future__ import print_function`

is not the first line, and I get the following error message:

```
File "test.sage.py", line 6
from __future__ import print_function
SyntaxError: from __future__ imports must occur at the beginning of the file
```

Here is a MWE. The file "test.sage" containing:

```
from __future__ import print_function
print(1+1)
```

is preparsed to "test.sage.py" containing:

```
# This file was *autogenerated* from the file test.sage
from sage.all_cmdline import * # import sage library
_sage_const_1 = Integer(1)
from __future__ import print_function
print(_sage_const_1 +_sage_const_1 )
```

Of course, I could manually add this line to the .sage.py file and then execute it, but this could be tedious in my case for two reasons: 1. I have a lot of files which I have to modify and rerun every 15 minutes. 2. I also need this process to be automatic to be able to execute it with automatically generated script and even sageTeX.

Thanks in advance for your answers!

Just use .py files. Preparsing is not really useful once you are used to sage.

The problem is that Sage executes .py files as purely Python files, so commands like

`plot`

are not recognized. Of course I can use Sage as a library an import it into the .py file, but unfortunately, the software I am working with require to first build .sage files.Then just import what you need. The command "import_statements" is very useful to find the required imports.

This seems like something that could be fixed in the .sage file preparser.

Do you need to include the line

`from __future__ import print_function`

?`print(x)`

should work fine without it.
