Description

Object Bucket is a python package that allows you to store python objects permanently in a more user friendly way.

---

Installation

The object-bucket package can be installed by using pip.

pip install object-bucket

---

Usage

• Creating new bucket.

from object_bucket import Bucket

test_bucket = Bucket("name-of-the-bucket")

• Adding droplets to the bucket, droplets are considered as objects that you want to save permanently.

test_obj = [1, 2, 3, 4]
test_bucket.add_droplet("droplet-name", test_obj)

Trying to add a droplet with the same name will cause an error.

• Adding multiple droplets. To add multiple droplets you have to have a dictionary that contains all the names and objects of the droplet. To add the dictionary you can use the add_droplets method.

droplets = {
      "one": 1,
      "two": 2,
      "three": [2, 3, 4]
  }

  test_bucket.add_droplets(droplets)

• Modifying a droplet

new_obj = {1: "a"}
test_bucket.modify_droplet("droplet-name", new_obj)

Trying to modify a droplet that does not exists will cause an error.

• Saving a bucket

All the things mentioned above will not be added or saved permanently, to do so it is necessary to save the bucket.

test_bucket.save_bucket()

• Retrieving values from a bucket.

from object_bucket import Bucket
test_bucket = Bucket("name-of-the-bucket")
a = test.bucker.get_droplet("droplet-name")
print(a)  # {1: "a"}

Trying to get a droplet that does not exists will cause an error.

• Get all the runtime droplets

drop1 = [1, 2, 3, 4]
drop2 = "Hello"
drop3 = {1: "a", 2: "b"}
test_bucket.add_droplet("drop1", drop1)
test_bucket.add_droplet("drop2", drop2)
test_bucket.add_droplet("drop3", drop3)

# to get all the droplets
a = test_bucket.get_all_droplets()
print(a)

# output
{"drop1": [1, 2, 3, 4], "drop2": "Hello", "drop3": {1: "a", 2: "b"}}

• Deleting a bucket To delete the bucket and to clear the runtime storage of all the droplets.

test_bucket.delete_bucket()

• You can also delete a bucket using remove_bucket function

from object_bucket import remove_bucket
remove_bucket("name-of_bucket_to_be_removed")

Using the context manager.

It might be a hastle to remember to save to bucket, so you can use the context manager to avoid using the save_bucket method.

Note: Using Bucket().delete_bucket inside the context manager is useless as at the end the file will be saved automatically.

from object_bucket import Bucket

with Bucket("name-of-the-bucket") as b:
  # code to execute
  b.add_droplet("name", 1)
  # ...etc
  b.delete_bucket()  # wont work as the file will be again saved,
  # but the runtime contents will be cleared

Some more stuff

• You can use the if statement to check whether a bucket is empty or not

from object_bucket import Bucket
t = Bucket("name")
if t:
  print("Hello")  # -> does not print anything as bucket is empty

t.add_droplet("demo", 1)
if t:
  print("Hello 2")  # -> prints "hello 2" as the bucket has at least one droplet

• To get the number of droplets in a bucket you can use the len method

from object_bucket import Bucket
t = Bucket("name")
print(len(t)) # -> 0
t.add_droplet("demo", [1, 2, 3])
print(len(t)) # -> 1
