find out whether a module exists (without importing it)

[Michael Poeltl]

in my opinion, "without importing it" makes it unnecessarily complicated.
You just want to know it module xyz exists, or better said can be found
(sys.path).

why not try - except[ - else ]

try:
    import mymodule
except ImportError:
    #  NOW YOU KNOW it does not exist
    #+ and you may react properly
??
