[Tutor] importing strings

[Patrick]

I would like to import a string with a "placeholder" in it.

for example  "this is a %s"

I would then like to insert the value into it after importation, "this
is a %s" (test)

I have been able to import a string from another module threw a
dictionary but I can't seem to figure out how to do it so that I can
insert a value into the %s placeholder afterwards.

I can send over more code if this is an incomplete description.

Thanks in advance-Patrick
