'pass' and 'continue' have two very different meanings.
'pass' means 'don't do anything'; it's useful when you _have_ to put a
statement but you _don't_need_ to put a statement.
You can use it everywhere you want, with no other damage then adding a
little weight to your code.
A stupid example:
if i == 0:
'continue', to be used in a loop (for or while) means 'ignore the rest
of the code and go immediatly to the next iteration'. The statement
refers to the nearest loop; so, if you have two nested loops, it refers
to the inner one; another stupid example:
for i in range(10):
for j in range(10):
if j < 5: continue
do_something(i, j) # called only if j >= 5
