  • 0

I have a number of variables which are set and later in my code I want to use these variables together as one single variable with a . separation.

For example

Release=1
Build=2
ServicePack=3
Hotfix=4

Directory=Release.Build.ServicePack.Hotfix

I understand that the above line will not work but I’m not sure how to join the variables together when declaring the last one.

In my example I would like the Directory variable to equal '1.2.3.4'.

Th end goal here is to use os.path to create a directory based on the value of Directory. Given this would a better alternative to use os.path.join and pass in the individual variables instead of a single one?

    Directory = '.'.join(str(x) for x in (Release, Build, ServicePack, Hotfix))

    Turn each variable into a string. Join them together with a ‘.’ in between. 

    os.path.join("path/to/base", Directory)

    will work fine, resulting in

    path/to/base/Release.Build.ServicePack.Hotfix

    If I were you, I’d either use all caps for those variables, meaning they’re constants, or all lower case, as specified in PEP 8.
