How Much Python Code is Used in Fedora ?

only you can answer that question!
look at what package the app belongs to, and see if that's a python program, if it depends on python etc.

why is it not enough for you to know that python is really, really important?

i mean, what would you like to do with the answer if you got one?

Just curious actually

Identify all the directories from which utilities can be/are run. For example: /usr/bin
For each of those directories

Code:

grep '#!.*python' /usr/bin/*

to see a list of the utilities using python, or

Code:

grep '#!.*python' /bin/* | wc -l

to get a count of them.

Essentially, look in each file to see if it contains a #! line containing python.

There's probably a much more elegant way to do that, including looking at only the first line of each file, etc.

On my CentOS desktop, there are 119 such utilities in /usr/bin

code golf!

Code:

IFS=:; for i in $PATH; do for j in $i/*; do [[ "$(head -1 "$j")" == "#!"*python* ]] && echo "$j"; done; done 2>/dev/null | wc -l

(probably requires bash)

I'm afraid, you will never get a correct answer. It depends on what is installed, what is used, and actually it will even [always] differ on two [almost] identical installations.
(and also you will never know which part of the python code found on your host was/is/will be in use).

Found below answer from another forum :

For Linux or the basic code, I would say zero.
Even the command line stuff (ls, cp cat....) are in C.

Some GUI stuff may be in C++.
dnf is, I believe in python.,

Most of gnome is in javascript. KDE is in C++ (QT based)

I don't think "most of" gnome is in javascript. As far as I know, it's primarily in C (i.e., the stuff listed in Platform libraries).

Yes, I need to agree. The base system does not need python at all, just probably you won't be able to use a few tools.
If I knew well gnome is written in C or C++, but you can add panels and other dialogs, gui elements in python.
Especially there is a package python-gnome2 (for example)

So we can safely assume that Fedora Distribution has dependency on Python but Python is not directly used in as a programming language?

that is correct.
but not safe to assume.

Not sure how the language used to write Yum and DNF could be described as "not directly used", but whatever.

One of the group member of fedora forum said that :

I would have to say that most of the Fedora/Redhat written applications are written in Python. I am pretty sure that anaconda (The installer application) was written in Python. I believe firewalld is Python as well.

too much.
