Greetings,
I have a query regarding running a python program. When I try and run and python program from the tutorial folder it shows me the following:
a@a:~/repos/ns-3-allinone/ns-3.26$ ./waf --pyrun first
Waf: Entering directory `/home/asayel_25/repos/ns-3-allinone/ns-3.26/build'

Can anyone help?

Unlike C++ examples, you need to specify the relative path to the python
program, and include the program full name with the .py suffix.

I believe that ns-3.26 release was the first one with the 'check-config'

option to Waf.
When you run './waf --check-config' (or when you view the configure
output), do you see Python bindings enabled or disabled? You need to see:
Python Bindings : enabled

It is disabled, how can I fix it?

You need to have Python development libraries installed (see the
> It is disabled, how can I fix it?
installation wiki) and then you need to have the correct version of
Pybindgen installed per your ns-3 version.
If you downloaded ns-3.26 release as part of the 'allinone' source
archive, then pybindgen is already there (one level up from ns-3.26), so
you probably need to just add python development libraries (e.g. sudo
apt-get install python-dev) for your system.
This documentation may also help:
