What is the argument order for dump?

Short answer. The object first, then the file object.

How many objects does one load() call read?

Exactly one.

Remember

dump(object, file)
load(file) reads one object

Save a list to a file and get a list back? Dump takes the object first, then the file. Load reads the same list back, roll one and marks eighty eight. Remember two things. Dump takes object, then file. Load reads one object.
