Formatting dashes into number

I have an id number (idnum)that is equal to 12345678. And is needs to be formatted to look like 123-45-678, which is equal to (new).

    newid = (int(idnum[:3]) + "-" + (int(idnum[4:6])) + "-" + (int(idnum[7:9]))

That is what I'm typing but its not working. The error I'm getting is "int not subscriptable."

You can't split an integer into its digits while maintaining it as an integer.

Your best option is to convert your number to a string and then manipulate it accordingly.

i.e.

idnum_str = repr(idnum) #number as string
newid = idnum_str[:3] + "-" + idnum_str[4:6] + "-" + idnum_str[7:9]
print(newid)
