A)
B)
C)
D)
Explanation:
The code involves serializing a list (rec) into a file. The correct module for serializing and deserializing Python objects into a file is pickle.
Explanation:
-
Statement 1: To serialize and deserialize objects, we need to import the
picklemodule. -
Statement 2: The file mode should be
"wb"(write binary) since we are writing serialized data. -
Statement 3: To serialize and save the data to the file, the
pickle.dump()method is used. -
Statement 4: The file should be closed using
f.close().
Correct answer:
(C) pickle
