I do not know the background of your user, but here is my try:
Loading a Python module at runtime is like loading a song, picture, or
web page. An import statement is like a web page link. If the name of
the resource is misspelled, or if the resource is not available when
requested, it cannot be loaded and the requesting progran can only
report an error. ImportError is equivalent to http's "40x: not found"
message. A web link that works one time may not work another time.
