Particularly since you're converting a remove to a copy...
I suppose if you're used to the sort of terse code filled with magic
characters that you find in bash, then the Python code might seem a bit
verbose. And I suppose you would be right :) But trying to do something
complicated in bash rapidly becomes *far* more verbose, unreadable and
clunky than Python.

Then write a helper function, and call that.
# Untested.
def copy(glb, destination):
if not isinstance(glb, str):
glb = os.path.join(*glb)
glb = glob.glob(glb)
for source in glb:
shutil.copy(source, destination)
