I am automatically building a package. The automated script needs to get the version of the package to build.
I need to get the string of the python script main.py. It says in line 15

```
VERSION="0.2.0.4" #DO NOT MOVE THIS LINE

```

I need the 0.2.0.4, in future it can easily become 0.10.3.15 or so, so the sed command must not have a fixed length.
I found this on stackoverflow:

```
sed -n '15s/.*\#\([0-9]*\)\/.*/\1/p'

```

"This suppresses everything but the second line, then echos the digits between # and /"

This does not work (adjusted). Which is the last "/"? How can I save the output into a variable called "version"?

```
version = sed -n ... 

```

throws an error
