try:
    import foo
except ImportError:
    foo = None

def function():
    if foo:
        return foo.func()
    else:
        do_something_else()



Or, alternatively:

try:
    import foo
except ImportError:
    import alternative_foo as foo  # This better succeed!

def function():
    return foo.func()
