Set permnission with makedirs

[Gribouillis]

Should not only display the umask but also set it !?

I just wanted to show the default value of the umask on my system. I chose the value 0 at random. Choose the value that you actually need for your file operation.

In the linux console, the current umask can also be displayed by invoking the umask command without argument

Output:
λ umask
0002

You could perhaps try

os.umask(os.umask(0) & ~(0o005))

to make sure that the umask does not prevent the "others" permission 5, or even

os.umask(os.umask(0) & ~(0o0755))

to make sure that the umask doesn't disallow the mode 0755
