Challenge: Exploring Object Memory

You are analyzing the memory behavior of a small data processing script. Your goal is to inspect reference counts, observe the integer cache, and measure object sizes using the tools covered in this section.

You are given the following list of transaction amounts:

transactions = [100, 200, 100, 300, 100, 200]

1. Import the sys module.
2. Store the integer 100 in a variable called small_int and store the integer 1000 in a variable called large_int.
3. Store the result of small_int is transactions[0] in a variable called is_cached — this checks whether the small integer cache is in effect.
4. Store the result of large_int is 1000 in a variable called is_large_cached.
5. Store the size of the transactions list in a variable called list_size, using sys.getsizeof().
6. Store the reference count of small_int in a variable called ref_count, using sys.getrefcount().
7. Print all four variables: is_cached, is_large_cached, list_size, and ref_count.
