program called twice from the command line [on hold]

Let's say I have a (Python3) script of my own named myscript; for various reasons, myscript (not myscript.py) is stored in a sub-directory named bin :
mydir/
mydir/bin/
mydir/bin/myscript -rwxr-xr-x
myscript begins with the usual shebang line, namely :
#!/usr/bin/env python3
When I'm in mydir/, I call my script this way:
$ ./bin/myscript
The result is tantalizing (to me !), myscript being called twice ! I get something like:
sh: 1: myscript: not found
*** specific message defined in myscript ***
The first line is clearly a sign that the shell tries to find a command named myscript. The second line is what I wrote in myscript.
Why is my script called twice ?
shell command-line python command

@Kusalananda mentioned that it's possible your script is calling myscript using system(). When you call with system I would guess the containing directory of myscript is not in the $PATH variable of the shell at that point, so you would need to pass the full path of myscript, not the relative path.

You're 100% right... My script checks if it's already installed by calling...os.system(myscript --version)...
