Asumes Python 3 version of subprocess module

[Fernando Brucher]

Binary package hint: pydf

In line 63:
def get_terminal_width_resize():
    c = subprocess.getoutput('resize').split('\n')

The call to subprocess.getoutput() is valid only in Python 3.
But the 1st line is: #! /usr/bin/python
Thus assuming the system default Python version is 3.

There's another call to subprocess in line 293, which is also invalid.

I fixed my script by changing the 1st line to:
#! /usr/bin/python3

But the package dependencies only require python >= 2.2, so this is clearly not a valid fix.

Package erroneously wants to force install of Python 2 if only Python 3 is installed on system, the fix should rather be to remove the Python 2 dependencies.
