  Now, "dt_expiry" exists in /two/ modules: In "scoping2" and in the
  current module (as a copy). To avoid this, "import scoping2" instead.

  This changes the variable "dt_expiry" in "scoping2", but not the
  copy (also named "dt_expiry") in the current module.

> >>> print(dt_expiry)
>1970-01-01 00:00:00+00:00

  This prints "dt_expiry" from the current module, not from "scoping2".

  To avoid this, replace "from scoping2 import *" by "import scoping2"
  and replace the "dt_expiry" in the two print statements by 
  "scoping2.dt_expiry".
