Saving the times a script is run to a file or ...

[3Pinter]

Hi,

I have a lot of scripts from which I'd like to know the amount of times it was run.

I coded a working version a long time ago plus I was even more a beginner than I'm currently. So I'll show you what I have, then perhaps you have a better understanding.

Scope:
- several .py-files
- on network location (local)
- multiple users run those files.
- all of these files run my "log" function at the end of the file.
- log function saves to a network .txt file (simple dump).

Function:

def log():   
    import __main__ 
    project_nummer = projectnumber()
    date = datetime.now().strftime("%d %B %Y")
    dyn_naam = os.path.basename(__main__.__file__)[:-10]
    
    log_path = "T:\\Folder1\\Folder2\\myscripts.log\\"
         
    bestand = log_path + "mylog.txt"
    
    input = dyn_naam + "\t" + project_nummer + "\t" + date + "\n"
    exists = os.path.isfile(bestand)
    
    if exists:
        with open(bestand, "a+") as f:	
            f.writelines(input)	
        return "Log: {} {}".format(log_path, input)
    else:
        print "No log file exists"

My questions:
- which is the better format? I now would say json due the library style
- what if two users run (different) scripts at the same time. Could the file be 'open' thus creating an error? If so: can I catch that?
- is this saving to a network location a good approach?
