What I want to do is very simple but I can't figure out a good and not too complex solution for this. Basically I want to define some global variables that will be used for example as a folder name 

```
global folder = "C:\\TEMP\\" + foldername

```

And what I want is to set the foldername value as input when running the script, something like:

```
python myscript.py --folder somebeautifulfoldername

```

so when running my script, the folder will become C:\TEMP\somebeautifulfoldername
